number of stations per cable, as shown in Figure 2.
Additional cables may be used to serve other stations
(see Figure 3).
Outside Stations
Run3conductor#22 twisted cable from the outside station
to the amplifier (Figure 3). The maximum cable length is
150' (45 m) and the maximum number of stations is two.
Music Input
Run2 conductor #22 shielded cable fromthe music input
source to the amplifier.
Door Release
IR704BD inside stations must be used if door release
functionis needed. Run 2 conductor#18cablefrom inside
station to inside station and to the amplifier. Run 2
conductor #18 cable from the door release location to
the amplifier. Keep cables away from station wiring.
