Kidde Edwards GCHFRF-S7VMCH Ceiling Speaker Strobe

Product Description

The KIDDE EDWARDS GCHFRF-S7VMCH is a ceiling-mount combination speaker and strobe unit designed for fire alarm notification systems. It delivers audible tone output at 520 Hz and visual strobe notification across a candela range of 95 to 177 candela, making it suitable for wide-area or high-ambient-noise environments. The unit operates on a 70-volt audio distribution circuit, which is the standard voltage level used in commercial fire alarm speaker wiring. Licensed fire alarm technicians and low-voltage contractors are the primary installers for this type of device. Note that this part has been marked as discontinued by the manufacturer and is no longer in active production.

This ceiling speaker strobe is intended for use in commercial fire alarm and mass notification applications where both audible and visual signaling are required by code. Typical installation environments include office buildings, schools, healthcare facilities, and other occupancies subject to NFPA 72 requirements. The unit mounts to a ceiling surface or a standard electrical box and combines two notification functions into a single device, reducing installation hardware and labor time.
