The Notifier FMM-101 is a miniature intelligent addressable monitor module designed to supervise a single Style B (Class B) dry-contact initiating device circuit (IDC). Its compact form factor allows it to be mounted inside a single-gang box directly behind the monitored device, making it ideal for retrofit and space-constrained installations.

The module communicates over the SLC loop using Notifier’s FlashScan protocol (or CLIP mode where applicable). It reports device status (normal, open, short) to the fire alarm control panel and uses rotary switches for direct-dial address setting.

The FMM-101 is powered directly by the two-wire SLC loop and does not require additional external power.
