Kidde Edwards GCHFWF-S7VMCH Ceiling Speaker Strobe 70V 520hz

Product Description

The KIDDE EDWARDS GCHFWF-S7VMCH is a ceiling-mount speaker strobe unit designed for commercial fire alarm notification systems. It combines audible and visible alerting in a single device, producing a 520 Hz tone output at 70 volts and delivering strobe output in the 95 to 177 candela range. This combination makes it suitable for high-ambient-noise environments where both audible and visual notification are required. Licensed fire alarm installers and low-voltage systems technicians are the primary trades who specify and install this device as part of an addressable or conventional fire alarm system.

This ceiling speaker strobe is intended for commercial and institutional applications where a single notification appliance must meet both audible and strobe requirements per fire code. Typical installations include office buildings, schools, healthcare facilities, and other occupancies subject to NFPA 72 notification appliance requirements. The 70-volt audio line configuration integrates with standard 70V distributed audio fire alarm panels. The 95 to 177 candela strobe output range allows for flexible placement to meet photometric coverage requirements in larger or open ceiling spaces.

Key Features

• Ceiling-mount design combines speaker and strobe in one notification appliance
• 70-volt audio line operation for compatibility with standard fire alarm panel audio outputs
• 520 Hz tone output meets low-frequency alarm signal requirements
• Strobe output range of 95 to 177 candela for flexible code-compliant placement
• Single-device installation reduces conduit runs and junction box count

Compatibility

Designed as an OEM-style ceiling notification appliance for use with 70-volt fire alarm audio systems requiring combined speaker and strobe functionality.

Installation Notes

Installation must be performed by a licensed fire alarm technician in accordance with NFPA 72 and all applicable local codes. De-energize the fire alarm control panel and silence the audio circuit before making any wiring connections. Verify strobe candela placement meets the photometric spacing requirements defined by the authority having jurisdiction before final mounting. Do not apply power until all connections are inspected and the panel is configured for the correct audio output voltage.
