The Fire-Lite MMF-301 is an addressable mini monitor module designed for compatible Fire-Lite intelligent fire alarm control panels. It provides an addressable interface for monitoring normally open dry-contact initiating devices, allowing conventional initiating devices to communicate with the fire alarm control panel over the Signaling Line Circuit (SLC).
Its miniature design allows installation inside a standard single-gang electrical box directly behind the monitored device, making it an excellent solution for retrofit applications and locations with limited installation space. This product is intended exclusively for commercial fire alarm installations.
The MMF-301 operates directly from the compatible Fire-Lite 15–32 VDC Signaling Line Circuit (SLC) and requires no separate operating power supply. Rotary decimal switches provide simple field addressing.
The initiating device circuit is supervised using the supplied 47 kΩ end-of-line resistor and supports up to 1,500 Ω of wiring resistance. The module is intended for concealed installation without rigid mounting inside a standard single-gang electrical box.
The MMF-301 is designed to fit inside a standard single-gang electrical box located behind the monitored device. Its compact dimensions allow installation where conventional monitor modules may not fit.
The module includes factory-installed wire leads to simplify wiring and eliminate the need for rigid mounting hardware, making installation faster while maintaining reliable system supervision.
Suitable for monitoring:
Compatible with:
Always verify compatibility with the installed Fire-Lite fire alarm control panel, SLC protocol, firmware version, and monitored initiating device before installation. The MMF-301 is functionally equivalent to the MMF-300 but is housed in a smaller enclosure for concealed installations.
