Party Line Introduction and Operation

Party Line Operation

The Zeus III integrates 32 4-wire intercom ports (ports 1 – 32) with two (2) 2-wire intercom ports (ports 33 and 34), allowing
audio to pass between the 2-wire channels and 4-wire channels. Any 2-wire system can be connected directly to the Zeus III
without an SSA-324 or a DSI-2008, saving the space and expense of supporting two (2) units to convert the signal.
IMPORTANT: Channels must be configured the same between products. For example, a PS-4001 connected to CH1 of
the Zeus III must be set to BAL on both units.
