Notifier FMM-4-20 Analog Input Module

The Notifier FMM-4-20 is an intelligent addressable analog input module that lets the NFS2-3030 monitor industry-standard 4-20 mA sensors such as gas, temperature, and air speed devices. It converts the sensor output into a communication format the panel can interpret, supports both 2-wire and 3-wire sensor configurations, and includes built-in short-circuit protection for reliable operation. Key Specifications: Type: Intelligent addressable analog input module Core Function(s): Interfaces 4-20 mA sensors to the fire alarm control panel for monitoring and display Loop/Protocol: Notifier SLC; FlashScan operation Power: 15 to 32 VDC from SLC; 700 uA max standby at 24 VDC. External power supply 12 to 28 VDC; 10 mA standby nominal (module only); 500 mA maximum external sensor current Indicators/UI: Panel-controlled bi-color LED; rotary address switches Sensor Support: Accepts both 2-wire and 3-wire 4-20 mA sensor configurations Protection Features: 500 mA current limiter, cutoff circuit, isolated external power supply, and transient/noise filtering Mounting: Mounts in a standard 4-inch junction box Wiring: SEMS terminals accept 12 AWG to 18 AWG System Compatibility: Designed for use with the NFS2-3030 fire alarm control panel with compatible firmware supporting FMM-4-20 analog input functions and programmable thresholds.
