The Kidde Genesis G4 Series EG4SRF is a wall-mount fire alarm speaker that delivers clear, intelligible audio across commercial spaces while barely adding an inch to the wall profile. Field-selectable wattage taps (1/4, 1/2, 1, or 2 watt) let you dial in output without removing the device - set it during install, adjust it after final inspection, no callbacks.
Built for the commercial fire installer
The sealed-back 4-inch mylar cone produces 80 to 89 dBA (UL 1480 rated at 10 ft) depending on wattage tap, with a frequency response of 400 to 4,000 Hz optimized for voice intelligibility. Available for 25 VRMS or 70 VRMS audio circuits, both with a built-in DC blocking capacitor for electrical supervision. Red housing with FIRE marking and room-side wiring plate included. UL and ULC listed (File Number S2813), MEA and CSFM approved.
