Kidde | Genesis G4 High Fidelity 520 Hz Wall Mount Mass Notification Speaker-Strobe, White, Multi-Candela Amber Lens, 25 VRMS | G4HFWN-S2VMA

The Kidde Genesis G4HFWN-S2VMA is a 520 Hz high fidelity wall mount speaker-strobe built for mass notification and alerting applications in commercial sleeping areas. The low-frequency output meets NFPA 72 requirements for newly constructed dormitories, hotels, and assisted living facilities where standard 3 kHz tones fall short. Pair it with a compatible mass notification system or audio source and it drops onto standard 4-inch square boxes with no special hardware.

Built for the commercial installer

Genesis G4 housings install on a universal mounting plate that fits any standard North American 4-inch square box (2-1/8" deep minimum). Wattage and candela settings are field-selectable from switches accessible at the bottom of the unit - no need to pull the device off the wall to reconfigure. Wire connections are room-side for faster termination. The low-profile, tamper-resistant housing is UV-stabilized ABS plastic that won't yellow or fade on long deployments.

Key advantages

• 520 Hz high fidelity output meets NFPA 72 sleeping area requirements for commercial occupancies

• Universal mounting plate fits standard 4" square boxes - no proprietary backboxes required
• Amber lens, no FIRE marking - purpose-built for mass notification and alerting, not fire alarm
• Synchronizable strobes via GSA-CC1S, GSA-MCC1S, SIGA-CC2A, and compatible sync modules
• UL 464, UL 1638, UL 1971, UL 1480, ULC-S541 listed and ADA compliant

System requirements

Requires a 25 VRMS audio source (mass notification system, FACP with audio output, or standalone tone generator) and 16-33 Vdc regulated or FWR power for the strobe circuit. Supports #18 to #12 AWG wiring. Optional EG4B surface mount box available when flush mounting isn't practical.
