The Kidde G4LFRF-HVM is a high-performance, low-frequency horn strobe designed to meet the latest fire and life safety standards, particularly in sleeping areas where enhanced alerting is critical. Emitting a 520 Hz square wave tone, it is proven to be more effective at waking individuals, especially those with hearing impairments. The unit features a bright visual strobe and a loud audible output, all housed in a bold red casing clearly marked with “FIRE” for easy identification. Engineered for use in hotels, dormitories, hospitals, and residential buildings, this Genesis G4LF Series device operates at 24VDC and delivers dependable, code-compliant emergency signaling in both new installations and retrofit projects.
