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
