The Bogen PCMZPM module provides three zones of paging to the PCM2000 system. Up to three PCMZPM modules can be used in a basic system to provide up to nine zones of paging. Additional modules can be combined with a PCMCPU module in a satellite system when more than nine zones are required. Each PCMZPM module lets you set the talkback option (on or off) and background music options for each zone. Each zone can be connected or disconnected from the background music bus.
