Installation

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.
