Wiring the System
Depending on distance, use twisted pair, 14-22 AWG audio cables when wiring the Wired Intercom System,
components. Figure 7 shows an overview of the cable types and number of conductors required for each unit.
Table 1 shows wire gauge required for different distances between components. We recommend installing a
separate power supply transformer (3M part number 78-8095-0910-8), for each Station Selector located over 100
feet from the Communications Controller,
Note:
The RS 485 cable carries DC power for the Station Selectors, requiring a larger gauge wire.
