Notifier FMM-4-20 Analog Input Module

The Notifier FMM-4-20 is an intelligent addressable analog input module that allows the NFS2-3030 fire alarm control panel to monitor industry-standard, linear-scale, 4–20 mA protocol sensors. The module converts the sensor output to a communication protocol that can be interpreted by the FACP for monitoring and display.

Compatible with a wide range of 4–20 mA sensors — including gas, temperature, and air speed sensors — the FMM-4-20 provides versatile functionality for fire safety and environmental monitoring. The external power supply is isolated from the SLC, and a 500 mA current limiter with cutoff circuit protects against short circuits. The module features rotary address switches, a panel-controlled bi-color LED, SEMS screw terminals accepting 12 to 18 AWG wire, and mounts in a standard 4-inch junction box. It operates exclusively in FlashScan mode.
