Kidde - Edwards G4LFRF-H 520hz Low Frequency Horn

Product Description

The KIDDE - EDWARDS G4LFRF-H is a 520Hz low frequency horn designed for fire alarm notification applications. Low frequency audible devices operating at 520Hz are recognized for improved effectiveness in alerting occupants who may not respond to traditional 3100Hz tones, including those with certain hearing impairments. This unit is finished in red and carries fire alarm labeling, making it appropriate for life-safety notification systems. Licensed fire alarm technicians and electricians install this type of device as part of addressable or conventional fire alarm circuits.

The G4LFRF-H is suited for commercial and residential fire alarm systems where low frequency audible notification is required. It is typically installed in sleeping areas, corridors, or other occupancies where code or authority having jurisdiction (AHJ) mandates low frequency signaling. This device falls within the sound and strobe notification appliance category and is sold as an individual unit.
