The Genesis G4LF wall-mount horn delivers a 520 Hz low frequency tone that meets NFPA 72 requirements for sleeping area notification. Drop it onto a standard 4-inch square box, wire into the existing NAC, and the job is done - no special mounting hardware, no adapter plates.

Built for fire alarm installers

UL 464 and ULC S525 listed. The G4LF runs on 16-33 VDC (filtered or FWR), pulling from the same NAC circuit as the rest of the Genesis notification appliance line. Temporal Code 3 pattern is built in - no external coding needed from the FACP. White housing with no "FIRE" marking for applications where the AHJ or building owner wants a clean aesthetic.
