The Kidde Genesis GCHFWA-S2VMCH is a high fidelity 520 Hz ceiling speaker-strobe built for commercial sleeping areas, dormitories, and hotels where NFPA 72 requires low-frequency audible signaling. The white housing with ALERT marking supports mass notification applications, and the multi-candela high cd strobe (selectable 95/115/150/177 cd) covers a wide range of room sizes from a single SKU.

Built for the commercial fire installer

This device mounts flush to any standard North American 4-inch square electrical box (2-1/8" deep) or 960A-4RF round flush box - no extension ring or trim plate required. The low-profile design sits just 1" off the ceiling, 30% slimmer than comparable signals. Wattage taps (1/4W, 1/2W, 1W, 2W) and candela settings are field-selectable without removing the device - open the cover, adjust the switches, and close. Settings remain visible through front windows after installation.
