• Addressable Monitor Module

The Fire-Lite MMF-302 Interface Module is intended for use in intelligent, addressable systems, where the individual address of each module is selected using built-in rotary switches. This module allows intelligent panels to interface and monitor two-wire conventional smoke detectors. It transmits the status (normal, open, or alarm) of one full zone of conventional detectors back to the control panel. All two-wire detectors being monitored must be UL compatible with the module. The MMF-302(A) can be used to replace M302(A) modules in existing systems.


  • Supports compatible two-wire smoke detectors
  • Supervises IDC wiring and connection of external power source
  • High noise (EMF/RFI) immunity
  • SEMS screws with clamping plates for ease of wiring
  • Direct-dial entry of address: 01 - 159 on MS-9600 series
  • panels, 01 - 99 on other compatible systems
  • LED flashes during normal operation
  • LED latches steady to indicate alarm on command from
  • control panel
