The Kidde FX-RLY provides a programmable relay output on the SLC loop, giving installers direct control of external appliances, HVAC shutdown, or notification circuits without dedicated control wiring back to the panel. Rotary address switches and low standby current (125 A) keep commissioning fast and loop loading minimal.
Built for the commercial fire installer
UL and ULC listed. The FX-RLY connects to any Kidde FX Series Intelligent FACP via the Signaling Line Circuit and occupies a single address. The Form C dry relay contact handles pilot-duty loads up to 30 VDC at 2A or 125 VAC at 0.5A (60 W / 62.5 VA max), covering most ancillary control scenarios on a commercial fire job. It mounts in standard 4-inch square electrical boxes installers already have on the wall.
