System Wiring

The maximum line length for the complete system, while still maintaining maximum output signal, is

4.5 km/15,000 feet for a system with less than ten stations using 1 mm

wiring, with 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.
