GENERAL INFORMATION
The following general procedures must be observed in relation to the location and
installation of System One Home Communication components:
Stations are not to be installed back to back or in line of sight of each other, as this will
cause feed-back (squealing).
Where stations are to be fitted externally, appropriate measures to provide protection from
the weather are to be taken.
Avoid running intercom cable in parallel to electrical wiring.
The plugpack should be located in an area with sufficient space for heat dissipation.
Guidelines for maximum cable lengths as set out in this manual are to be observed to
avoid the possibility of operating problems due to excessive voltage drop.
The maximum number of stations on any system including the Master and Door Station is
generally limited to 20.
It is important that the power supply is properly matched to the size of the system.
CAUTION:
Failure to use specified cable may cause problems with the performance of the system
and will void warranty on the equipment.
IMPORTANT:
Responsibility will not be taken for problems that arise from the use of improper cable or
interference generated externally to the system.
Interference by light dimmers, fluorescent lighting and similar electrical products, must be
corrected at the source.
An aid to reducing the effects of this type of interference is to place stations and wiring no
closer than 30cm (12”) from any AC device or wiring.
The circuitry of the intercom has been designed to minimize the effects of Radio
Frequency Interference however total immunity to this type of interference cannot be
guaranteed where the levels of interference generated are extreme.
1

LOCATION OF EQUIPMENT
MASTER STATION
Where a Master has been purchased as part of the system, it is generally located above
the breakfast bar in the kitchen/family room at a suggested height of 1400 millimetres from
the floor to the centre of the unit. As all wiring from other stations is generally terminated at
the rear of the Master, the wall should be no less than 70 millimetres in depth. A timber
wall box should be inserted so as to allow for correct support of the Master station.
IMPORTANT:
The Master Station should be installed in a cavity wall and not a single brick wall in order
to facilitate the wiring behind it.
Where there is wall tiling around or near to the Master Station, ensure the Master Station
is mounted either completely within or completely clear of the tiled area as failure to do so
will result in the Master being affixed to an uneven surface.
ROOM STATIONS
Careful consideration must be given to present and/or future layout of furniture so as not to
locate stations in positions that will prove to be inappropriate.
To avoid audio feedback, Room Stations should be kept at least four to five meters away
from other stations. Never have more than one station in any one room and avoid
mounting stations in the same wall cavity (i.e. directly below and above one another in a
two-storey house).
A suitable height is generally 1400 millimetres from the floor to the centre of the unit.
Stations located on timber frame walls should be located adjacent to a stud to allow for
firm fixing.
Stations located on cavity brick walls will require the installation of wall boxes.
Stations installed on single brick walls will also require wall boxes however the cable will
need to be placed in conduit and chased into the brick wall. The rear of the brick wall will
need to be rendered or lined, as the depth of a Room Station is approximately the same as
a brick.
Where stations are required in bathrooms or laundries, they must be kept clear of water or
steam.
Where stations are mounted on a tiled surface, a wall box should be installed prior to
lining/tiling of the walls and the tiles will need to be cut to the inside dimensions of the wall
box.
Where Room Stations are mounted outside and are exposed to the weather, the fitting of
weatherproof covers will be required.
Stations must not be installed in saunas.
2

FRONT DOOR/GATE STATION(S)
These stations are best located adjacent to the front door or at the front gate at a
suggested height of 1400 millimetres and may require a wall box depending upon the
surface to which they are to be affixed.
Any station exposed to the weather will require the fitting of a weatherproof cover.
Where stations are to be installed in brick or concrete columns at a front gate, the cable
should be run in conduit from the stationto below ground level and back to the house.
POWER SUPPLY
The power supply is usually located no less than 1 metre and not more than 5 metres from
the Master (or from the Room Station that serves as a central connection point).
Suggested locations are kitchen cupboards, pantry, bedroom wardrobes etc.
The plugpack should be located with sufficient space to dissipate heat effectively.
It is desirable to have easy access to the power supply for occasions when power to the
system needs to be switched off and back on again.
AM AND FM ANTENNAS
The antenna arrangement is a critical part of the installation if quality radio reception is
required.
The AM and FM antennas should be located in the highest point of the roof and at least 2
meters away from any electrical or intercom wiring.
Because both the AM and FM antennas are directional, experimentation with positioning is
recommended to achieve the best possible result.
Where the roof is lined with foil insulation, or is of metal construction, it may be better to
have the AM antenna situated externally.
FM reception can be greatly improved in poor signal areas by connecting a specialized FM
antenna or by tapping into an existing TV antenna through a splitter.
AUXILIARY INPUT JACKS
The Auxiliary Input Jack is an optional accessory allowing music from an external source,
such as a tape deck, CD player, Walkman or computer, to be played throughout the
intercom system.
Two different types of Input Jack are used:
1) Wireless Audio Transmitter - only for use in systems with a Master
2) Input Jack Type B - for use in systems with or without a Master
The Input Jack Type B should be installed in a wall near the location where the external
music source is to be situated.
NOTE: An appropriate lead will be required to connect the music source to the Input Jack.
3

AUXILIARY/LOCK OUTPUT BOARD
The Auxiliary/Lock Output Board is an optional accessory allowing electronic door locks,
automatic gates, courtesy lights, etc to be controlled from the Master or any Room Station.
There are 2 outputs on each board, which can be individually programmed to time out or
toggle depending on the application.
4 of these boards can be fitted to any one system allowing a total of 8 auxiliary outputs in
total.
There is provision in the Master for the fitting of an Auxiliary/Lock Output Board on the
inside of the metal fascia.
Room Stations allow for the fitting of an Auxiliary/Lock Output Board in the side
compartment of the Room Station back housing.
NOTE: Additional wiring is required for this feature to operate.
WHERE TO RUN CABLE?
Cables can be run:
��In the roof space
��In false ceilings/bulkhead area
��Through and/or around external walls
��Under floors (subject to access being available)
��Underground in conduit
Intercom cables should be run as far away from AC wiring as practicality permits.
Avoid running intercom cable in parallel to AC or any other type of wiring.
(Running across at right angles is OK where necessary)
All antenna wires should be taken to the highest and most accessible point in the roof.
Allow additional cable at each station for the purpose of termination.
(At least 1 meter for the Master)
In the case of cavity brick walls, ensure the wires are pulled through one of the holes at the
rear of the wall box.
4

WHAT CABLE TO USE?
GENERAL
System One is designed to operate using 8-wire cable. Operation however is also possible
using 6-wire cable, with the disadvantage that music will be muted at all Room Stations,
while private communication is in progress.
The system may be star wired from a central point or loop wired however the number of
stations on a loop is governed by the length of the loop.
(See section “Maximum Length For Cable Runs”)
Different cables have different characteristics hence it is recommended that Valet Cable be
used on all new installations. Many other cables will work acceptably however responsibility
cannot be taken for problems that arise from the use of other cables.
The proper use of shielded cable on VLC & TC terminals will prevent "clicks & pops"
caused by Control Voltage changes being induced onto audio lines.
Clearly tagging all cables at the Master or central wiring point is strongly recommended as
this can be extremely helpful in isolating damaged cables or other system faults.
POWER SUPPLY
If a power supply is being used with a standard cable already attached to it, any required
cable extension should not be added to the end of the existing standard cable.
Where the existing cable length needs to be extended, the existing cable should be cut to
a length of only 10cm.
A heavy duty "Figure 8" cable should then be properly connected to the end of the 10cm
cable from the Power Supply and run to the Master (or the Room Station serving as a
central connection point).
The total resistance of the power supply cable should not be greater than 0.4 divided by
the total system current.
i.e. 0.4
P o w e r S u p p l y C a b l e
R e s i s t a n c e ( i n o h m s )
T o t a l S y s t e m
C u r r e n t ( i n a m p s )
where the total system current = sum of the peak current of all the stations on the system
As a guide for cable resistance:
The typical return resistance of the standard wire attached to a plugpack is
approximately 0.17 ohm per metre.
The typical return resistance for "24 x 0.2 Figure 8" wire is approximately 0.05 ohm
per metre.
EXAMPLE
For a system with a maximum current draw of 2A, the maximum allowable power supply
cable resistance is 0.2 ohm (calculated by: 0.4 divided by 2A).
The maximum length for standard plugpack cable in the above example would be
approximately 1.2 meters (calculated by: 0.2ohm divided by 0.17ohm).
The maximum length for "24 x 0.2 Fig 8" cable in the above example would be
approximately 4 meters (calculated by: 0.2ohm divided by 0.05ohm).
5

AM AERIAL
The coaxial cable supplied with the Master is fitted with a plug at one end and a socket at
the other end, which allows for plugging together multiple lengths of coaxial cable for
extended runs.
The plug and socket is to be cut off at both ends of the coaxial cable run for connection to
the Master and the AM loop antenna.
The cable is to be run from the Master to the highest point in the roof where the loop
antenna must be connected to both the inner core and the outer shield of the coaxial
cable.
FM AERIAL
The 300 ohm FM ribbon antenna supplied with the Master is to be run from the Master to
the highest point in the roof.
If using coaxial cable to connect to an alternative 75 ohm antenna, be sure to fit a
300 ohm/75 ohm balun to the terminals at the Master.
AUXILIARY INPUT JACKS (OPTIONAL)
Two different Input Jacks are available:
Wireless Audio Transmitter
- Can only be used on systems incorporating a Master
- Requires no cabling between the Master and the Input Jack
Input Jack Type ‘B’
- For use with “Room Station Only” systems
- Can also be used for “Master” systems
- Run 6-core cable (or same wire as used for intercom wiring) from the Input Jack to the
Master (or the Room Station serving as the central connection point).
AUXILIARY/LOCK OUTPUT BOARDS (OPTIONAL)
An additional hook-up wire (13 x 0.13 or similar) is required between all Room Stations
(and Master if fitted).
Heavy duty "Figure 8" cable is to be run from each relay output (via the power source if
required) to the applicable auxiliary device.
To minimise the undesirable effects of cable voltage drop, the total resistance of the cable
connecting the auxiliary device, auxiliary board relay, and the power source, for the
auxiliary device, should be approximately 1/10 the resistance of the load represented by
the auxiliary device itself.
6

MAXIMUM LENGTH FOR CABLE RUNS
The system may be "star wired" from a central point or "loop wired" however the number of
stations on a loop wired run governs the overall length of the run.
The table below shows the relationship between the length of a cable run and the number
of stations permitted on the run.
A cable run is considered to begin at the station to which the power supply is connected.
Number of stations for a given cable run length
Cable run length No. of stations permitted
51 to100 metres 1 station
34 to 50 metres 2 stations
26 to 33 metres 3 stations
1 to 25 metres 4 stations
These maximum distances can be doubled where required by running a “figure 8” cable
(14 x 0.2 mm) in parallel with the POS & NEG wires.
It is vitally important that the POS and NEG wires are balanced in terms of the type of wire
and the number of wires used - i.e. if a Fig 8 wire and a Valet wire are used for POS, a Fig
8 wire and a Valet wire should also be used for NEG.

Note: The maximum length (in metres) of any individual wiring run = 100 divided by the number of stations on the run.
i.e. The maximum length for the cable run connecting the Master and Rooms 3,4 & 5, is
100m ÷ 3 stations = 33 metres in total.
(The master is not used in the calculation because it is the station to which the power supply is connected)
A Load Resistor is not required for systems using a Master unless older version VR101
Room Stations or VF101 Door Stations are being used. If these are being used, a 220K Load
Resistor must be fitted to the LOAD RES terminals and the indicated track below the LOAD
RES terminals on the termination PCB must be cut.

A Load Resistor is required on Room Station Only systems. In the examples
above, the Load Resistor should be fitted across the VLC and NEG terminals
of Room 1 (the Room Station to which the power supply is connected).

INSTALLATION OF VR102 ROOM STATIONS
ROOM STATIONS IN TIMBER FRAME WALLS
Cut hole in wall lining keeping one side of the cut out adjacent to a stud so as to allow for
firm fixing.
Fit Room Station housing into cut out and mark positions for wall fixing attachments.
Remove housing and cut out a 5 to 7 millimetre vee for the fixing point of the wing toggle
bolt.
Pull any cabling through the Room Station back housing and fit the back housing into the
cut out hole securing it with the fixing attachments provided.
Strip back the outer white covering of the cable (approximately 80 mm), then strip the
individual wires (approximately 6 mm).
Firmly fix all bare wires into the appropriate screw terminals. Ensure bare wire from one
terminal does not touch the bare wire of another.
Secure the front fascia onto the back housing using the four 12mm screws provided.
(It is suggested that these screws be only partially screwed in until system has been fully
tested)

For Room Station Only systems (Systems without a Master), a load resistor must be fitted
across the VLC and NEG terminals of the station to which the power supply is connected.
Although a 220K resistor is supplied with each Room Station, only one of these resistors is
to be fitted to a Room Station Only system.
When fitting a load resistor to a Room Station, take care that the legs of the resistor do not
short against the speaker when the fascia is attached to the back case.
Because Master Stations have a Load Resistor built in to the circuitry, the fitting of an
external Load resistor is generally not required for Master systems.

INSTALLATION OF VF103 DOOR STATIONS
These stations are best located adjacent to the front door or at the front gate at a
suggested height of 1400 millimetres and may require a wall box depending upon the
surface to which they are to be affixed.
Any station exposed to the weather will require the fitting of a weatherproof cover.
Where stations are to be installed in solid brick or concrete columns at a front gate, it is
required that the cable be run in conduit from the station to below ground level and back to
the house.
When using 8-wire cable to connect to the Door Station, do not connect the spare two wires
to the MUS1/MUS2 terminals at the Master Station (or Room Station) end of the cable.
The two spare wires from an 8-wire cable may be wired in parallel to the POS and NEG
wires to the gate station, to double the maximum cable distance to a length of 200 metres.
Where a Door Station is part of a wiring loop, the Door Station should generally be the last
station on the loop.

WIRING VOLTAGE OUTPUTS
The Lock output (LK) and Chime voltage output (CH) will provide 12 Volt DC @ 50mA
which can be used to power up relays which in turn will switch voltage to the device being
used.
WARNING
Using these outputs to drive a load, with a resistance of less than 240 ohm, will damage
the output transistors.
Check coil resistance of relays to be used with a multimeter.

INSTALLATION OF AUXILIARY INPUT JACK - TYPE B
(For systems with or without a Master)
INSTALLATION IN TIMBER FRAME WALLS
Cut out the wall lining so as to allow the circuit board to be recessed into the opening.
Mark the mounting points and fit appropriate wall plugs.
Pull the cable through the opening, strip the required wires, and screw into the terminals of
the Input Jack as indicated on the diagram.
Screw the Input Jack to the wall.
INSTALLATION IN CAVITY BRICK WALLS
NOTE: A standard "HPM Stand Off Mounting Block" is recommended, as it may be
difficult to enlarge the hole in the brickwork to allow recessing of the
circuit board.
Drill through the brickwork to the cavity.
Pull the cable through the opening.
Drill and plug the brickwork at the mounting points for the "Stand Off Mounting Block."
Pull the cable through the mounting block and screw the mounting block to the wall.
Strip the required wires and screw into the terminals of the Input Jack.
Screw the Input Jack to the mounting block.
CONNECTION TO AUDIO SOURCE
The Input Jack Type B has two RCA sockets fitted to its front plate, which allows for
connection to an audio source such as a CD player, tape deck or computer.
A separate audio connection lead will need to be purchased with 2 x RCA plugs at one
end and a plug (or plugs) at the other end to suit the audio source being used.
Some common Audio Leads used are:
“2 x RCA plugs to 2 x RCA plugs” (for CD player, DVD player or tape deck).
“2 x RCA plugs to 3.5mm stereo plug” (for MP3 player, computer, portable stereo,
tape or CD walkman).
“2 x RCA plugs to 6.5 mm stereo plug” (for headphone output on stereo systems).

INSTALLATION OF WIRELESS AUDIO TRANSMITTER
(Only for systems fitted with a Master Station)
CONNECTIONS
Connect the plug pack to the Wireless Audio Transmitter.
Connect the audio output of a PC, CD player, TV, or any other device with an audio output,
to the 3.5mm stereo input jack on the Wireless Audio Transmitter.
Connect the plug pack to the power point and switch the power point on.
INSTALLATION OF AUXILIARY OUTPUT BOARD
FITTING AN AUXILIARY OUTPUT BOARD AT THE MASTER
On a VM102 Master Station, there are four mounting posts to the right of the speaker, on
the rear of the metal front, for the mounting of an Auxiliary Output Board.
Four M3 x 6mm screws are supplied in the Master kit bag for fitting the Auxiliary Output
Board to these mounting posts.
The 4-way wiring loom supplied with the Auxiliary Output Board connects the 4-way
header on the Auxiliary output Board to the 4-way header on the Intercom PCB which is
located directly above the Auxiliary Output Board.
The Master Station has a set of "13.8V O-P" terminals, which can be used to supply
power through the Auxiliary Output relay contacts, to the auxiliary device being used.
FITTING AN AUXILIARY OUTPUT BOARD AT A ROOM STATION
The Auxiliary Output Board will slide into the side compartment on the right hand side of
the back housing of any Room Station.
The 4-way wiring loom supplied with the Auxiliary Output Board connects the 4-way
header on the Auxiliary output Board to the 4-way header on the Intercom PCB which is
attached to the Room Station fascia.
It is recommended that power being switched through the Auxiliary Output Board relay
contacts, to the auxiliary device, not be taken from the POS and NEG terminals on the
Room Station, but rather from a separate power source. This is to prevent a voltage drop
at the Room Station while the auxiliary device is being powered.
NOTE: The relay contacts on the Auxiliary Output Board are Dry Contacts. They act as a
switch and do not output a voltage on their own.
IMPORTANT: For this feature to operate from all stations, the “AUX” terminal at each
station including the Master (if fitted), is to be linked by a single wire.
WARNING: This board is not designed to switch High Voltage directly. A separate
suitable relay can be used in conjunction with this board, where the switching of High
Voltage is required.

INSTALLATION OF POWER SUPPLY
A regulated 13.8V dc power supply is required to power the system.
For systems using a Master, it is imperative that a LINEAR regulated supply be used, as
SWITCH MODE regulated supplies will cause interference with AM radio reception.
NOTE: - Since some linear supplies also generate interference, it is recommended that
only power supplies recommended by a Valet Dealer be used.
- See sections "LOCATION OF EQUIPMENT" and "WHAT CABLE TO USE" for
important details on power supply location and cabling.
POWER SUPPLY CURRENT RATING
It is important to use a power supply with a current rating sufficient for the size of the system.
The power supply current rating is determined by the peak current requirement of the system
as a whole and can be calculated by adding the peak current requirement of each of the
stations making up the system.
The table on the right shows the current
consumption for each of the individual
components.
The following calculation example is for
a system made up of a Music Master,
6 Rooms and 1 Door.
1 x 0.45A for the Master = 0.45A
6 x 0.15A for six rooms = 0.9A
1 x 0.15A for the door = 0.15A
Total = 0.45A + 0.9A + 0.15A = 1.5A
System One Item Current
Master Station – Music 0.45A
Master Station – Secure 0.5A
Room Station 0.15A
Door Station 0.15A
Auxiliary Input Jack 0.1A
External Siren 1A
External Strobe 0.1A
The above system requires a 13.8Vdc linear regulated supply rated at 1.5 amp or better.
CONNECTION TO A MASTER SYSTEM
For a system fitted with a Master Station, the power supply is to be connected to the
Master Station.
The Master Station has a dedicated pair of terminals labelled "13.8V I-P" on the
termination PCB for the connection of the power supply.
Because a DC power supply is used, it is important that the positive lead of the power
supply connects to the POS terminal and the negative lead of the power supply connects
to the NEG terminal.
38

CONNECTION TO A ROOM STATION ONLY SYSTEM
For a system not fitted with a Master Station, the power supply is to be connected to a
Room Station.
Where the system is star wired, the power supply should connect to the Room Station to
which all other stations have been wired.
Where the system is loop wired, it is recommended that the power supply be located
centrally in the system, as shown in “Figure A” below, as the length of a run of cable is
calculated from the station to which the power supply is connected.
Figure A
Figure B
Total Cable From First Station to Last station = 100M
Room 1 Room 2 Room 3 Room 4 Door
Cable Run No. 1 = 50M
Total Cable From First Station to Last station = 100M
Cable Run No. 1 = 100M
Cable Run No. 2 = 50M
ACCEPTABLE
Room 1 Room 2 Room 3 Room 4 Door
UNACCEPTABLE
In Figure A, there are effectively two cable runs of 50M each, with two stations on each
run. This is acceptable because it is permissible to have two stations on a 50M run of
cable (see section " MAXIMUM LENGTH OF CABLE RUNS").
In Figure B, there is only one cable run of 100M in length, with four stations on the run.
This is unacceptable because it is only permissible to have one station on a 100M cable
run (see section " MAXIMUM LENGTH OF CABLE RUNS").
The power supply connects to the POS and NEG terminals of the applicable Room Station.
Because a DC power supply is used, it is important that the positive lead of the power
supply connects to the POS terminal and the negative lead of the power supply connects
to the NEG terminal.

POWERING UP THE SYSTEM
For the VM102-S with wireless security, remove the shunt from the 2-way header at the
bottom of the security PCB, located in the top left hand corner of the Master fascia
(looking from the rear).
For the VM102-S with wireless security, ensure that the 12V battery is not connected.
For all systems, ensure all the stations and accessories have been installed and correctly
terminated.
Plug the power supply into a power point and turn the power point on.
If the power supply is fitted with its own power switch, turn the switch on.
If the system is fitted with a Master, the radio/clock should illuminate.
For a Room Station only system, press the house talk button at any Room Station,
checking that the green L.E.D. turns on while the button is being pressed.
With a multimeter, measure the DC voltage, at the terminals to which the power supply are
connected.
The measured voltage should be between 13.2 and 14.2 Volts DC.
If the voltage measures low, or the displays and L.E.D.s are not working, turn the power
supply off immediately. Identify and correct the fault before proceeding any further.
If everything appears to be in order, and the system is fitted with a VM102-S Master with
security, connect the battery ensuring that the polarity is correct.
The small lamp on the left side of the termination PCB may glow dimly indicating that the
battery is being charged.
If the lamp glows very brightly, there is a problem that needs to be rectified.

VM102 MASTER STATION PROGRAMMING
To access the following programming options, the Master must be in PROGRAM mode.
To enter PROGRAM mode, press the PRIVACY and MONITOR buttons simultaneously.
When all the program options have been entered, press the CANCEL/CLEAR button to
exit PROGRAM mode.
MASTER STATION CODING
For the purpose of Select Calling (calling individual or grouped stations), the Master must
be allocated either a Single Digit or Double Digit number. If the same number is allocated
to other stations besides the Master, the Master and the Room Stations having the same
number will form a group. Allocating a number to the Master is done by means of keypad
programming as outlined below.
Single Digit Coding
Single Digit format is the default programming setting intended for systems requiring up to
8 select call channels.
This format offers the convenience of calling individual or grouped stations by pressing
only one button.
NOTE: Single digit format is compatible with the previous VR101 Room Stations.
If not previously programmed, the Master will be in the default setting of Single Digit
format, where in program mode, the red L.E.D. will repeatedly flash a string of 1 to 8
flashes representing the (Single Digit) programmed number (default number = 1).
Enter a number between 1 and 8 by pressing the corresponding button.
The red L.E.D. will now repeatedly flash the newly programmed number.
Exit program mode by pressing the “CANCEL/CLEAR” button, or remain in PROGRAM
mode to program more options.
Double Digit Coding
Double Digit format is a programming option intended for systems requiring from 9 to 24
select call channels.
This format requires that two buttons be pressed in sequence to call individual stations.
NOTE: Double Digit format is not compatible with the previous VR101 Room Stations.
If not previously programmed, the Master will be in the default setting of Single Digit
format, where in PROGRAM mode, the red L.E.D. will repeatedly flash a string of 1 to 8
flashes representing the Single Digit programmed number (default number = 1).
Press the “AUX” button to toggle to Double Digit Mode.
In Double Digit mode the red L.E.D. will repeatedly flash the following information.
- 2 quick flashes representing Double Digit Mode
- 1 to 3 flashes representing the first digit (default = 1)
- 1 to 8 flashes representing the second digit (default = 1)
42

Enter a Double Digit number in the ranges of, 11 to 18, 21 to 28, or 31 to 38
(24 possibilities in total).
The red L.E.D. will repeatedly flash the following information.
- 2 quick flashes representing DOUBLE DIGIT Mode
- 1 to 3 flashes representing the first digit of the new number
- 1 to 8 flashes representing the second digit of the new number
Exit PROGRAM mode by pressing the “CANCEL/CLEAR” button or remain in PROGRAM
mode to program more options.
NOTE: - SINGLE and DOUBLE DIGIT format cannot be mixed in one system.
- Each station is to be individually programmed to the same format.
- Repeated pressing of the “AUX” button, while in PROGRAM mode, will toggle
between SINGLE and DOUBLE DIGIT formats.
KEYPAD BACKLIGHTING
The VM102 Master has keypad backlighting, which can be toggled on and off, by pressing
the “DOOR” button while in PROGRAM mode.
SIX WIRE OPERATION
Although System One is designed to operate optimally using 8-wire cable, it will also
operate using 6-wire cable if required.
On 6-wire systems, music is interrupted at all stations during private communication
whereas with 8-wire systems, music is only interrupted at the stations involved.
Selecting Six Wire Mode
Where the Room Stations on a 6-wire system are programmed to the “6-wire” option, the
Master on a 6-wire system, must be left programmed to the “8-wire” option.
Selecting 6-wire mode at the Master is done with two wire links and a jumper.
In accord with the cable termination diagrams for VM102 Masters using 6-wire telephone
cable, ensure the following:
��COM1 terminal is linked (with wire) to the MUS1 terminal
��COM2 terminal is linked (with wire) to the MUS2 terminal
Fit the shunt provided, across the link labelled “L1” on the audio interface PCB, situated on
the bottom right hand corner, on the rear side of the Master fascia.
In PROGRAM mode, ensure the green L.E.D. is on (8-wire mode).
If it is not, press the “HOUSE” button to select “8-wire” mode (green L.E.D. on).
Press the “CLEAR” button to exit PROGRAM mode, or leave in PROGRAM mode, to alter
other programming options.

VM102 MASTER STATION ADJUSTMENTS
SETTING PRESET INTERCOM AUDIO LEVELS
Set the slide volume controls at all Room Station to approximately level "4."
Disconnect speaker at Door Station.
Adjust VR2 at Door Station so that the chime rings at an acceptable level at the Room
Stations.
Reconnect Speaker at door.
Adjust VR1 on the Door Station, so the chime rings quietly at the Door Station.
Adjust the blue hand fitted trim pot on Master Intercom PCB (above and to the right of the
Master speaker) so the chime rings at the same level at the Master as it does at the Room
Stations.
MICROPHONE GAIN
Microphone Gain is adjusted by means of a miniature trim-pot on the Intercom PCB, which
is the PCB above and to the right of the speaker, on the rear of the Master fascia.
The trim-pot is labelled VR2 and is located towards the top of the PCB.
This pot is normally set to 50% and will rarely require adjustment.
Adjustment will only be necessary on larger systems (15 to 20 stations) where the
accumulated loading effects of all the Room Stations will result in lower communication
levels.
Where adjustment is necessary, use the correct flat bladed screwdriver with a blade width
of between 2 and 2.5mm to avoid damaging the pot.
There are no detectable start and stop positions on this pot, which means that it can be
unknowingly rotated past maximum, where it immediately returns back to minimum.
The best way to adjust this pot to maximum is by measuring its resistance with an ohmmeter,
with power to the system turned off.
The resistance can be measured across the bottom two pins of the pot.
The resistance reading of the pot in the standard 50% position is typically between
2200 and 2300 ohm.
While measuring the two bottom pins of the pot, rotate the pot clockwise until its resistance
reads between 10 and 100 ohm. This position represents maximum microphone gain.
NOTE: Where this pot requires adjustment, the same adjustment is normally done at all
other stations on the system, including the Door Station.

START UP
VM102-Secure restarts by powering down and powering up the system (including battery),
by removing and refitting the shunt on the back of the security PCB, or by a system reset
caused by possible electrical interference.
When the unit is restarted it briefly allows entry into PROGRAM mode (refer to section
“PROGRAMMING”). Following this, the unit enters the previous operational mode. If the
unit was in ARMED, HOME, or HOME 2 mode, it will show the mode on the display for 30
seconds. During this period triggers from the main PIR are ignored, allowing it time to
settle. After this, the unit resumes normal operation in the mode displayed. This process
will occur silently, without the usual arming sounds.
USER MODES
The system can be in one of four user modes, DISARMED, HOME, HOME 2 and ARMED.
From the DISARMED mode, pressing "ON" enters ARMED mode, a second "ON" press
enters HOME mode, and a third "ON" press enters HOME 2 mode (provided devices are

ALARMS
Intruder Alarms
Following this type of alarm the internal and external sirens sound and strobe flashes.
The siren will turn off after the programmed siren time and the strobe will flash for 1 hour.
The "OFF" button cancels any alarm and puts the VM102-Secure into the DISARMED
state.
When disarming after an alarm, the VM102-Secure will indicate an alarm has occurred.
The strobe flashes and siren will beep rapidly for 5 seconds (both internal and external,
even if external chirps are disabled).
This warning may indicate that an intruder is still present.
The source of the alarm is then displayed for 5 minutes. Intruder alarms are not indicated
when the system is in ARMED, HOME or HOME 2 modes.
A time stamp is appended to each of the following alarm messages when displayed.
For example, if the alarm occurred within 24 hours, the time stamp would be appended
as: ... < XX HRS < XX MIN < AGO.
If the alarm event was older than 24 hours, the time stamp would be appended
as: ... < X DAY < XX HRS < AGO.

54

ENTRY & EXIT DELAY
EXIT DELAY is the time, between pressing the "ON" button and the system being
ARMED, during which detector activations are ignored. The siren will chirp once when the
"ON" button is pressed to indicate the start of EXIT DELAY and chirp once at the end of
exit delay to indicate the system being ARMED.
A warning tone at the end of EXIT DELAY indicates an unsealed reed switch, specified as
displayed.
ENTRY DELAY is the time between the activation a detector and the system being
DISARMED, during which, detector activations do not cause an alarm. During ENTRY
DELAY the siren will chirp once a second. When the "OFF" button is pressed the siren
chirps 3 times to indicate DISARMED. If the "OFF" button is not pressed within the ENTRY
DELAY, the siren sounds and strobe flashes.
ABORT DELAY
When an alarm event occurs, the siren sounds when ENTRY DELAY expires. The alarm is
sent to the monitoring station only after ABORT DELAY expires. ABORT DELAY
commences immediately after ENTRY DELAY expires. This gives the user time to abort
the sending of an accidental alarm by pressing the "OFF" button within the ABORT DELAY
period.
ABORT DELAY is a programmable option. If ABORT DELAY is programmed to 0, then an
alarm will be sent at the expiry of ENTRY DELAY, i.e. user CANCEL cannot be sent. If the
"OFF" button is pressed before ABORT DELAY expires, a user CANCEL message will be
sent. (CANCEL is a non-actionable event for the monitoring station, but it makes the
monitoring station aware that the system had been briefly triggered before a user cancel.)
LOCKOUT
Alarm lockout inhibits multiple activation’s of the same alarm (excluding panic) i.e. the
external siren will not sound again until the "OFF" button is pressed (alarm cleared). The
internal siren will always sound if the option is OFF. If the option is "ON" both the external
and internal sirens will be locked out (as required by AS2201.1)
RUNAWAY
Runaway limits the number of times an alarm from a particular device will be sent to the
monitoring station. After 3 alarms have been sent, no further alarms for that device will be
sent to the central station until the system is DISARMED and ARMED again.
This feature prevents a large customer phone bill being incurred if, for example, a door
protected by a reed switch is left unlatched and swings open and shut many times.
Runaway is permanently enabled.
55

PROGRAMMING
VM102-SECURE uses a common “LEARN” mode to listen for programming messages
from new devices. The installer does not specify a slot number instead the unit allocates
the next available slot when a device is accepted.
Learning New Devices
1. On the VM102-Secure Master, remove and replace the 2-way shunt on the security PCB.
2. The software revision number is displayed briefly.
3. If unit has no keys programmed, it will display LEARN / KEY 1 until a key is programmed,
otherwise the unit flashes LEARN and waits 10 seconds to receive a radio key message:
��If "OFF" is pressed on a programmed key, the unit enters PROGRAM mode,
displaying the first programmed key.
��If "ON" is pressed on a programmed key, the unit enters PROGRAM mode,
flashing READY and listening for a LEARN message from a new device (key or
detector).
��If a LEARN message is received from an unprogrammed key, the unit will add
the key to the next available slot and display the new slot number, then allow the
user to configure the new key.
��If none of the above occur after 10 seconds, the unit enters OPERATE mode.
(This is only the case if there is at least one radio key already programmed.)
4. To cause a device to send a LEARN message:
Device Mode Learn Procedure
Key Encrypted Hold down PANIC button for approximately 8 seconds.
Sensor Encrypted Disconnect and reconnect battery.
If the device is successfully programmed, VM102-Secure will give a "BEEP, BEEP,
BEEP, BEEP." The unit will add the new device to the next available slot, display the
new slot number, and allow the user to configure the new device. If the key or device is
already programmed an error sound "BBRRRR" will occur.
This also applies if the method of programming an encrypted key or device is incorrect.
For example, if you try programming in an encrypted key by pressing the "OFF" button
three times, the error sound "BBRRRR" will be heard.
Press "OFF" to return to LEARN.
Press "ON" to flash READY and learn another device.
Or press "OFF" to step through devices and program options.
56

Configuring Devices and Options
In PROGRAM mode, the display remains steady when displaying devices (programmed
keys and detectors) and system options (EXIT TIME etc). The display flashes when
displaying the current programmed value for each device or option. Various beeps give
audible feedback during the programming process.
��Press "OFF" (on a programmed key) to step through the devices and options.
��Press "ON" to view the value for that option (flashing). Press the "ON" button again
to step through alternative values (non flashing).
��Press the PANIC button to store the displayed value (causing it to flash).
��Press "OFF" to step to next device/option.
Programming Notes
Program stepping requires a programmed key.
Each time a programming change is made, the new value will be flashing and is stored
immediately in non-volatile memory.
A programmed device can be erased, by selecting ERASE. The display will then show
LEARN, giving the user the option of reprogramming a new device into this particular slot.
This allows a faulty device to be replaced while keeping the same slot number.
VM102-Secure will flash FULL if an attempt is made to program a device when there are
no more slots available. It will allow programmed devices to be viewed in sequence and
erased if desired.
A key cannot be used to erase itself. A device cannot be programmed more than once.
The VM102-Secure will give a long warning beep if either of the above is attempted.
The VM102-Secure will automatically exit PROGRAM mode after 10 minutes of inactivity.

PROGRAMMING RADIO DIALLER
Local Programming
1. Ensure Radio Dialler is powered up. The Radio Dialler only needs to be powered off and
on if a different Client Account Number is to be programmed into VM102-SECURE.
2. Power up VM102-SECURE and press "OFF" to enter PROGRAM mode.
3. To program the Radio Dialler, the VM102-SECURE must have at least the PHONE1
option set to a value other than the default value of “-”.
4. Finish programming the VM102-SECURE and exit PROGRAM mode. If PHONE1 has
been programmed, and if data transfer to Radio Dialler has not been successful within
a short period of time, VM102-SECURE will display a system alarm indicating a radio
link failure with the Dialler.
After VM102-SECURE has been operating continuously for 30 days, the Options CLIENT,
PHONE1 and PHONE2 will no longer appear in PROGRAM mode and therefore cannot be
changed locally. They may be changed using the up/download facility at any time and local
programming of them can be re-enabled using up/download.
Remote Programming
1. Ensure Radio Dialler is powered up. Radio Dialler does not need to be powered off and on.
2. Remove and replace the 2-way shunt on the VM102-S security PCB and press "OFF"
to enter PROGRAM mode. The Radio Dialler will now be ready to answer incoming
calls for the next 5 minutes. If the Dialler answers a call but does not verify within 30
seconds it will hang up. Once a connection is established, the Dialler will hang up
unconditionally after 5 minutes or when a "hang up" is requested sooner from the
remote end.
3. Once a connection is established, program the VM102-SECURE RADIO DIALLER
system as required.
4. VM102-SECURE will exit PROGRAM mode when the up/down connection is
terminated, or when the VM102-SECURE PROGRAM mode timer expires, whichever
occurs first. If PHONE1 has been programmed and if data transfer to Radio Dialler has
not been successful within a short period, VM102-SECURE will raise a system alarm
indicating radio link failure with the Dialler.
Supervision
VM102-SECURE transmits supervision messages to Radio Dialler every hour. A system
alarm is raised if the Dialler does not acknowledge the message after the programmed
number of hours in the SUPERVIS option.
58

Alarms
VM102-SECURE places alarm events for transmission to the Radio Dialler on a queue.
When it transmits, it transmits the next message on the queue. If an "acknowledge" is not
received from the Dialler, the VM102-SECURE re-transmits the message for a total of 10
attempts. If still unsuccessful, the VM102-SECURE ceases transmitting until a new event
occurs and raises a system alarm.
The oldest messages on the queue are sent first. If the queue is full (10 messages), a new
message will overwrite the oldest message.
Dialler Status
Dialler status is sent to the VM102-SECURE when a condition changes, and VM102-
SECURE raises a system alarm as required.

DIALLER
The Radio Dialler will allow a correctly configured VM102-Secure, to report alarms to a
central monitoring station via the telephone line.
It also provides remote programming of VM102-Secure, using a PC with “Up/download”
software and a modem.
Alarm Reporting
This reporting is used to transmit alarms from a customer’s site to a central monitoring
station via the telephone.
There are 2 phone numbers, a primary number PHONE1 and a secondary number
PHONE2. Reports are usually sent on the primary number but if the dialler is unsuccessful
in connecting, it will dial the secondary number. Telephone numbers must be programmed
into the system.
The monitoring company allocates a unique client account number to each customer for
identification. This client account number must be programmed into the system.
New alarms initiate a dial out report. Pressing the "OFF" button on a programmed key will
deem the new alarm as having been restored.
Alarms are reported to the central monitoring station by the dialler in "Contact ID" format.
Contact ID Reporting
This reporting is used to transmit alarms from a subscriber’s site to a central monitoring
station via the telephone line.
The transmission is done using DTMF tones. An alarm message consists of 15 digits plus
an error check digit (8 bytes). The format is as follows:
SSSS 18 Q XYZ GG CCC E
SSSS 4 digit Client Account number
18 Uniquely identifies this format as Contact ID
Q Event qualifier (1 = New alarm or Open; 3 = Restore or Close)
XYZ Event code
GG Group code (always 00)
CCC Sensor/key ID and offset or Type number
E Error check

IMPORTANT NOTES:
To place the VM102-SECURE into program mode simply remove and replace the shunt on
the rear of the security PCB. The display will show the version number for 0.5 seconds
then flash “LEARN” for 10 seconds. During the 10 seconds the display is flashing
“LEARN”, pressing the “ON” button on any programmed key, will enable the VM102-
SECURE to receive signals from radio devices (both keys and devices). “READY” will be
flashing on the display.
The VM102-SECURE programs the device or key into the next available position. For
example, if there are already 4 sensors programmed, the next device will be programmed
as sensor 5. If a sensor or key is deleted, the next sensor or key will be programmed in the
erased position.
Programming details
��Programming Supervised / Encrypted PIR’s: With “READY” flashing on the display of
the VM102-SECURE, connect the 9 volt Lithium battery to the PIR. The VM102-
SECURE will respond with “BING-BING - BING-BING." The display will flash the
sensor number programmed (eg. “SENS 2”). If you try to program the sensor into the
VM102-SECURE by triggering the sensor the VM102-SECURE will respond with
“BING – BING – BBRRRR” invalid tone.
��Programming Encrypted Radio Keys: With “READY” flashing on the display of the
VM102-SECURE, press and hold the PANIC button. This sequence takes
approximately 8 seconds. The VM102-SECURE will respond with a “BING” when the
panic message is received, then “BING-BING - BING-BING." The VM102-SECURE will
flash the key number programmed (eg. “KEY 2”).
��Programming Supervised / Encrypted Reed switches With “READY” flashing on the
display of the VM102-SECURE, connect the correct lithium battery to the reed switch.
The VM102-SECURE will respond “BING-BING - BING-BING." The display will flash
the sensor number programmed (eg. “SENS 2”). If you try to program the sensor into
the VM102-SECURE by triggering the reed switch, the VM102-SECURE will respond
with “BING – BING – BBRRRR” invalid tone.
��Programming Supervised Panic Buttons: With “READY” flashing on the display of the
VM102-SECURE, connect the correct lithium battery to the panic button. The VM102-
SECURE will respond with “BING-BING - BING-BING." The display will flash the key
number programmed (eg. “KEY 6”). If you try to program the panic button or door bell
into the VM102-SECURE by pressing the front button, the VM102-SECURE will
respond with “BING – BING – BBRRRR” invalid tone.
NOTE: Panic buttons are recognised as KEYS.
��Programming Door Bells: With “READY” flashing on the display of the VM102-
SECURE, press and hold the BELL button. This sequence takes approximately 6
seconds, The VM102-SECURE will respond with a “BING” when the Bell message is
received then “BING-BING - BING-BING." The VM102-SECURE will flash the door bell
number programmed (eg. “KEY 7”).
NOTE: Door bells are recognised as KEYS.
72

��Programming the VM102-SECURE Radio Dialler: Program the CLIENT, PHONE 1
and PHONE 2 options into the VM102-SECURE. Once the above is done continue
through the program options until P-EXIT is on the display. At this point, power up the
radio dialler with both mains and battery. The Radio Link light will double flash. Exit
VM102-SECURE program mode by pressing “ON” on a programmed radio key. This
will drop VM102-SECURE out of program mode and download the customer and
central station information to the Radio Dialler. The Radio Dialler will respond by
flashing out the signal strength on the indicator lights as well as beeping the signal
level. For testing purposes only, place a shorting link on J6 of the radio dialler. This will
allow you to hear the dialler call and respond to the central station tones, and then
hang up after sending the message. Don’t forget to remove the link on J6 after
completing this test. To test the "VM102-SECURE to Radio Dialler" signal strength
from this point on, simply put the VM102-SECURE into program mode. Cycle through
until P-EXIT is on the display then press the “ON” button on any programmed key to
exit program mode and the Radio Dialler will display and beep out the signal strength.
��You may find that sometimes when you remove and replace the reset shunt on the rear
of the security PCB that nothing happens. This is because the capacitors need more
time discharge. If you encounter this, wait a little longer (10-15 seconds) before
replacing the shunt.

VR102 ROOM STATION PROGRAMMING
To access the following programming options, the Room Station must be in PROGRAM mode.
To enter PROGRAM mode, press the PRIVACY and MONITOR buttons simultaneously.
When all the program options have been entered, press the CANCEL/CLEAR button to
exit PROGRAM mode.
ROOM STATION CODING
For the purpose of Select Calling (calling individual or grouped stations), each station must
be allocated either a Single Digit or Double Digit number. If the same number is allocated
to more than one station, the stations having the same number will form a group.
Allocating a number to a station is done by means of keypad programming as outlined
below.
Single Digit Coding
Single Digit format is the default programming setting intended for systems requiring up to
8 select call channels.
This format offers the convenience of calling individual or grouped stations by pressing
only one button.
NOTE: Single digit format is compatible with the previous VM101Master and VR101 Room
Stations.
If not previously programmed, the station will be in the default setting of Single Digit format
where, in program mode, the red L.E.D. will repeatedly flash a string of 1 to 8 flashes
representing the Single Digit programmed number (Default number = 1).
Enter a number between 1 and 8 by pressing the corresponding button. The red L.E.D. will
now repeatedly flash the newly programmed number.
Exit PROGRAM mode by pressing the “CANCEL/CLEAR” button, or remain in PROGRAM
mode to program more options.
Double Digit Coding
Double Digit format is a programming option intended for systems requiring from 9 to 24
select call channels.
This format requires that two buttons be pressed in sequence to call individual stations.
NOTE: Double Digit format is not compatible with the previous VM101 Master and
VR101 Room Stations.
If not previously programmed, the station will be in the default setting of Single Digit format
where, in program mode, the red L.E.D. will repeatedly flash a string of 1 to 8 flashes
representing the Single Digit programmed number (Default number = 1).
Press the “AUX” button to toggle to Double Digit mode.
In Double Digit mode the red L.E.D. will repeatedly flash the following information.
- 2 quick flashes representing Double Digit mode
- 1 to 3 flashes representing the first digit (default = 1)
- 1 to 8 flashes representing the second digit (default = 1)
Enter a Double Digit number in the ranges of, 11 to 18, 21 to 28, or 31 to 38
(24 possibilities in total).
74

The red L.E.D. will repeatedly flash the following information.
- 2 quick flashes representing Double Digit mode
- 1 to 3 flashes representing the first digit of the new number
- 1 to 8 flashes representing the second digit of the new number
Exit program mode by pressing the “CANCEL/CLEAR” button or remain in PROGRAM
mode to program more options.
NOTE: - Single and Double Digit format cannot be mixed in one system.
- Each station is to be individually programmed to the same format.
- Repeated pressing of the “AUX” button, while in program mode, will toggle
between Single and Double Digit formats.
KEYPAD BACKLIGHTING
The VR102 Room Stations have Keypad backlighting, which can be toggled on and off by
pressing the “DOOR” button while in PROGRAM mode.
SIX WIRE OPERATION
Although System One is designed to operate optimally using 8-wire hook-up cable, it will
also operate using 6-wire hook-up cable if required.
The trade off in using 6-wire cable is that music will mute at all stations during private
communication where as with 8-wire cable, music only mutes at the two stations involved
in communication.
Selecting Six Wire Mode
In PROGRAM mode, press the “HOUSE” button to select “6-wire” mode (green L.E.D. off).
Press “CLEAR” button to exit Program Mode or leave in program mode to alter any
programming options.
The station will toggle between 6-wire mode (green L.E.D. off) and 8-wire mode (green
L.E.D. on) each time the “HOUSE” button is pressed while in program mode.
NOTE: - Music lines (MUS1 and MUS2) are omitted.
- No wire links are required at Room Stations
75

VR102 ROOM STATION ADJUSTMENTS
MICROPHONE GAIN
"Microphone gain" is adjusted by means of a miniature trim-pot VR2 located towards the
top of the Room Station PCB.
This pot is normally set to 50% and will rarely require adjustment.
Adjustment will only be necessary on larger systems (15 to 20 stations) where the
accumulated loading effects of all the Room Stations will result in lower communication
levels.
Where adjustment is necessary, use the correct flat bladed screwdriver with a blade width
between 2 and 2.5mm to avoid damaging the pot.
There are no detectable start and stop positions on this pot, which means that it can be
unknowingly rotated past maximum, where it immediately returns back to minimum.
The best way to adjust this pot to the maximum gain position is by measuring its resistance
with an ohmmeter, with power to the system turned off.
The resistance can be measured across the bottom two pins of the pot.
The resistance reading of the pot in the standard 50% position is typically between
2200 and 2300 ohm.
While measuring the two bottom pins of the pot, rotate the pot clockwise until its resistance
reads between 10 and 100 ohm. This position represents maximum microphone gain.
NOTE: Where this pot requires adjustment, the same adjustment is normally done at all
other stations on the system including the Master (where fitted) and the Door
Station.

PROGRAMMING AND ADJSTMENTS FOR VF103 DOOR STATION
DOOR STATION ADJUSTMENTS
There are 3 adjustments on the Door Station that may require fine-tuning after installation.
A flat bladed screwdriver with a blade width between 2mm and 2.4mm is required for these
adjustments. Using the wrong screwdriver will damage the pot.
Speaker Volume
Speaker volume at the Door Station is adjusted by means of a miniature trim pot (VR1)
located in the centre of the circuit board.
Turning this pot will vary the speaker volume.
This adjustment can be made while someone is communicating to the Door Station from
one of the internal stations or while the chime is activated.
Chime Volume
Chime volume is adjusted by means of a miniature trim pot (VR2) situated at the bottom of
the circuit board as indicated below.
Turning this pot will vary the chime volume throughout the entire system.
This pot should be adjusted so the chime volume comes through at an acceptable level at
an internal Room Station with its slide volume control set to around level 4 or 5.
Microphone Gain
The microphone gain pot (VR3) is generally set half way and would rarely require
adjustment.
The microphone level can be turned down where the Door Station causes feedback in a
Room Station due to close proximity or can be turned up if the communication level from
the Door Station is too low - see "Adjustments for VR102 Room Stations" for more detail.

SETTING UP INPUT JACK TYPE B
If the Input Jack has been wired into an 8-wire system, ensure the jumper has been
removed from the two link pins labelled "L1".
If the Input Jack has been wired into a 6-wire system, ensure the jumper has been fitted
across the two link pins labelled "L1".
The volume control on the Input Jack should be adjusted for the desired volume at the
intercom stations with the Room Station volume controls adjusted to approximately 3/4 of
maximum.
The tone control should be adjusted 1/2 way or to personal preference.
SETTING UP WIRELESS AUDIO TRANSMITTER
Turn on the intercom radio and press the MUSIC button at the Master, to enable MUSIC
mode.
Tune the intercom radio to one of the FM frequencies listed in the table below that is not
being used by a commercial FM radio station.
If a clear frequency cannot be found, use one that is picking up only a weak radio signal.
Store this frequency into the memory of the intercom radio, as a "preset" station.
Using the table below, program the four miniature programming switches on the Wireless
Audio Transmitter to correspond with the FM frequency chosen.
The output of the audio device should now be audible through the intercom Master.

SETTING UP AUXILIARY OUTPUT BOARD
The fitting of an Auxiliary Output Board to the System One intercom allows devices such as door
strikes, automatic gates, alarm panic circuits, courtesy lights etc. to be controlled from the Master
or any Room Station.
Each Output Board provides two sets of "normally open" and "normally closed" dry relay contacts
(RELAY 1 and RELAY 2).
Four Output Boards can be used on a system providing a total of eight outputs.
The outputs can be set to toggle on and off with each activation, or time out after being activated
by means of bridging the appropriate jumper pins (M1 and M2).
The time-out duration can be adjusted from 1 to 45 seconds by means of adjustable trim pots
(VR1 and VR2).
The time-out duration can be extended up to approximately 10 minutes by adding a 330uF low
leakage electrolytic capacitor to position C2 for output 1 and position C8 for output 2.
The outputs are activated by pressing the AUX key on the intercom, followed by the number
(1 to 8), of the output to be activated.
DIP switches, are used to set the number that the output will respond to. Output 1 can be set to
respond to numbers 1, 3, 5 or 7 using DIP Switch 1 (DS1). Output 2 can be set to respond to
numbers 2, 4, 6 or 8 using DIP Switch 2 (DS2).
The board is located in the side compartment of any Room Station and is connected to the main
board of the Room Station by means of a 4-way Loom (power to be turned off and speaker to be
removed to make this connection).
NOTE: The relay contacts act as a switch and do not output a voltage on their own.
IMPORTANT: For this feature to operate from all stations, the “AUX terminal at each station
including the Master (if fitted) is to be linked by a single wire.
WARNING: This board is not designed to switch High Voltage directly. A separate suitable relay
can be used in conjunction with this board where the switching of High Voltage is required.

CHECKLIST FOR 6-WIRE INSTALLATION
All the information required for a 6-wire installation is contained in the various sections of
this manual.
Below is a summary of items that need to be addressed for 6-wire operation.
1. Fit wire link between COM1 and MUS1 (at Master only).
2. Fit wire link between COM2 and MUS2 (at Master only).
3. Fit shunt across jumper “L1” on Audio PCB in Master labelled “AUXILIARY INPUT
BOARD”.
4. Leave Master programmed to “8-wire”.
5. Program each Room Station to “6-wire” as follows:
- Enter Program Mode by pressing the “PRIV” and “MON” buttons at the same time.
- Toggle between 6-wire and 8-wire modes by pressing the “HOUSE” button.
- Green L.E.D. on indicates 8-wire mode.
- Green L.E.D. off indicates 6-wire mode.
- Press “CAN” (CANCEL) button to exit program mode and lock in selection.
6. Wire Auxiliary Input Type B (if fitted) according to 6-wire instructions and ensure
shunt is fitted so as to bridge Link “L1”.
89

TROUBLE SHOOTING
Fault: Volume Control at Master does not adjust music level on a 6-wire system.
Fix: The conversion to 6-wire at the Master is achieved not by programming, but by fitting
wire links between the COM1 to MUS1 and COM2 to MUS2 terminals. Ensure Master is
programmed to 8-wire.
Fault: On a 6-wire system Music mutes when the talk button is pressed but returns as
soon as the talk button is released.
Fix: For 6-wire systems, music is transmitted on the same cables as communication
therefore music must be muted throughout the system whenever communication takes
place. To achieve this, ensure the jumper is fitted to both the link pins labelled L1 on the
Master Audio Interface PCB or the Auxiliary Input Jack for Room Station only systems.
Fault: House and door talk functions work correctly but no communication using numerical
private dialling.
Fix: Ensure Room Stations have been coded correctly and all stations are set to either
single digit or double digit dialling format.
Fault: Music and monitoring is not being received at certain Room Stations although
communication is being received okay.
Fix: Ensure that all stations are correctly programmed to either 8-wire or 6-wire
(Master must be programmed to 8-wire in all cases).
Fault: No communication or chimes, on a "Room Station Only" system.
Fix: - Ensure load resistor is fitted to system.
- Make sure the load resistor is not shorting against the speaker when the fascia is
attached to the Room Station.
- At all stations, ensure the VLC and TC wires are in the correct terminals and have
not been reversed.
- At all stations, ensure that there are no exposed wires at any terminals.
Fault: No communication or chimes on a "Master" system.
Fix: - At all stations, ensure the VLC and TC wires are in the correct terminals and have
not been reversed.
- At all stations, ensure that there are no exposed wires at any terminals.
