Kidde Edwards G4HFWN-S7VMB Wall Speaker Strobe 70V

Product Description

The KIDDE EDWARDS G4HFWN-S7VMB is a combination wall-mount speaker and strobe unit designed for fire alarm notification systems. It operates on a 70-volt audio circuit and produces a 520 Hz tone, which is the required frequency for sleeping area fire alarm audibility per NFPA 72 guidelines. The white housing suits standard commercial and residential interior installations. This unit is installed by licensed fire alarm technicians and low-voltage electricians as part of a listed fire alarm control panel system.

This speaker strobe is intended for wall-mount applications in commercial buildings, multi-family residential occupancies, schools, and healthcare facilities where both audible and visible notification is required by code. It combines audio output with a synchronized strobe flash in a single device, reducing the number of devices needed per notification zone. Typical installations follow NFPA 72 placement requirements for both audible and visible coverage.
