SYSTEM WIRING

Over 100 devices can operate on one network, but only 8 full-duplex conversations
can occur simultaneously.
The 2-wire network is connected by wiring intercoms in series. The positive network
wire of one unit is connected to the positive network wire of the second unit. The
negative network wires are connected similarly. Network wires between units must
remain paired in a 2 conductor or more cable. Twisted pair wiring is preferred but
not required for all installations. Both two unit wiring and multiple unit wiring are
shown below. The ends of a network are always completed with a terminator.
The following are recommendations for all installations:
(Also see Appendix A – Network Installation Tips).
• Use Belden 9463 Twinaxial cable when possible.
• Keep network wire pairs together at all times.
• Connect network units in series.
• Do not splice additional wires into network cable runs.
• Do not bundle excess network cable.
