Kidde Edwards G4LFWF-HVM 520 Hz Horn Strobe White

Product Description

The KIDDE EDWARDS G4LFWF-HVM is a combination horn and strobe notification appliance designed for fire alarm systems. It operates at 520 Hz, the frequency required by NFPA 72 for sleeping area fire alarm signals, making it suitable for applications where occupants must be alerted while asleep. The unit features a white housing with a fire-rated label and is intended for wall-mount installation in commercial and residential fire alarm notification circuits. Licensed fire alarm technicians and electricians install this device as part of a supervised, listed fire alarm system.

This horn strobe is used in fire alarm notification appliance circuits (NAC) in buildings requiring both audible and visible alarm output. Typical applications include hotels, dormitories, healthcare facilities, and multi-family residential buildings where code mandates 520 Hz audible output in sleeping areas. The white housing is appropriate for installations where aesthetics or facility standards call for a white finish rather than red.

Key Features

• 520 Hz audible output meets NFPA 72 requirements for sleeping area notification
• Combined horn and strobe in a single unit simplifies installation and reduces device count
• White housing suits facilities with white or neutral interior finish standards
• Fire-rated labeling identifies unit as part of the life safety notification system
• Wall-mount design integrates with standard fire alarm backboxes

Compatibility

Designed as an OEM-style replacement or new-installation horn strobe for use in supervised fire alarm notification appliance circuits. Consult the system engineer or authority having jurisdiction to confirm compatibility with the installed fire alarm control panel before ordering.

Installation Notes

Installation must be performed by a licensed fire alarm technician or electrician in accordance with NFPA 72, local fire codes, and the authority having jurisdiction. Disconnect and lock out power to the notification appliance circuit before wiring the device. Verify polarity on supervised NAC circuits prior to restoring power. A full system functional test is required after installation to confirm proper audible and visual output.
