DCP-DIMM | Hochiki's UL Approved Fire Detection

Dual Input Monitor Module | UL Addressable Fire Detection

DCP-DIMM Description 


DCP-DIMM (Dual Input Monitor Module) is designed for use on a UL-listed Fire Alarm Control Panel. It provides two independent contact monitoring circuits while only utilizing one address on the SLC loop.


Up to 127 devices can be placed on a single SLC loop. The device address is uniquely stored on an onboard EEPROM. The module can be programmed to monitor Normally Open (NO) or Normally Closed (NC) contact fire alarm and supervisory devices. The interrupt-driven Digital Communication Protocol (DCP) combines maximum communication reliability and fast response to emergency conditions. The module has a single bi-colored LED to indicate device status. It fits into a standard 4" square or double gang electrical back box.
