Kidde | Genesis High Fidelity 520 Hz Ceiling Speaker-Strobe, 70V Multi-Candela, White, Blue Lens | GCHFWN-S7VMB

The Kidde Genesis GCHFWN-S7VMB is a high fidelity 520 Hz ceiling-mount speaker-strobe built for commercial sleeping areas where NFPA 72 low-frequency signaling is required. The 70V speaker delivers crisp, intelligible voice audio from ¼ to 2 watts, and the blue-lens strobe provides field-selectable multi-candela output for mass notification applications - all in a low-profile package that fits flush on a standard 4-inch square box.

Built for the commercial installer

Mounts to any standard North American 4-inch square electrical box (2-1/8" deep) with no extension ring or trim plate needed. The shallow housing leaves room behind the signal for extra wiring, and #18 to #12 AWG screw terminals handle long runs and existing wire without re-pulls. Wattage and candela settings are accessible by unlatching the cover - no need to remove the device from the box - and switch positions stay visible through indicator windows after the cover is closed.

Key features

• Low-profile design: 30% slimmer than comparable signals, fits flush on standard 4" square boxes
