Product details
MMF-301 is a Fire-Lite miniature addressable monitor module that supervises one Class B (Style B) circuit of normally open contact devices on an intelligent SLC loop. Its small size lets it sit in a single-gang box directly behind the pull station, waterflow switch or other device it monitors. It can replace older M301 modules.
Key features
- Compact 1.3 × 2.75 × 0.65 in body mounts behind the monitored device
- Powered from the two-wire SLC; no extra power needed
- Tinned, stripped leads for quick wiring
- Rotary switches for direct address entry (01–159 on MS-9600 series panels)
- 47K end-of-line resistor included
