System Wiring
The maximum line length for the complete system, while still maintaining maximum output signal, is
15,000 feet for a system with less than ten stations. This is based on No. 18 AWG wire, the stations
spaced equidistantly, and one station in the talk mode at a time. For each station in talk mode, the signal
level reduces by half. For systems with more than ten stations refer to Figure 7 for the maximum line
distance.
