Conventional Zone Input Module

DCP-CZM, the Conventional Zone Module is designed for use on an analog addressable Fire Alarm system. Up to 127 devices can be placed on a single SLC loop. The device address is uniquely stored on an onboard EEPROM

The module allows the panel to interface and monitor two-wire conventional detectors or pull stations. Each DCP-CZM transmits the status on one zone of devices (25 maximum per zone) back to the panel. It supervises the power supply as well as the entire zone of devices. Status conditions are reported as normal, open, or alarm. All 2-wire smoke detectors must be UL listed as compatible to be interfaced with the DCP-CZM.

The interrupt-driven Digital Communication Protocol (DCP) combines maximum communication reliability and fast response to emergency conditions. The module has a single bicolored LED to indicate device status. It fits into a standard 4″ square or double gang electrical back box.
