Kidde | Genesis High Fidelity 520 Hz Ceiling Speaker-Strobe, Red, FIRE Marking, 25V, Selectable 95/115/150/177 cd, Clear Lens | GCHFRF-S2VMCH

The Kidde Genesis GCHFRF-S2VMCH is a high fidelity ceiling-mount speaker-strobe that delivers 520 Hz low-frequency signaling alongside field-selectable high-candela strobe output. Built for commercial fire alarm notification on 25V NAC circuits, it mounts directly to a standard 4-inch square box with no extension ring required.

Built for the commercial installer

The Genesis platform synchronizes flash and tone with compatible sync modules (GSA-CC1S, SIGA-CC2A, EG1M-RM, and others), keeping your notification circuits UL 1971 compliant without manual timing workarounds. UL 1638, UL 1971, and ULC-S541 listed. CSFM approved. Speaker-strobes comply with ADA Code of Federal Regulation Chapter 28 Part 36 for accessible audible and visible notification.

Key features
