Kidde - Edwards 879DEX-G1 Explosion Proof Horn Strobe

Product Description

The KIDDE - EDWARDS 879DEX-G1 is a supervised Adaptahorn horn strobe designed for 24 volt DC operation in explosion proof applications. This device combines audible and visual alerting in a single unit rated for use in hazardous classified locations where flammable gases, vapors, or combustible dust may be present. Licensed fire alarm and electrical contractors install this unit as part of a supervised notification appliance circuit, where the supervision feature confirms continuous circuit integrity for code-compliant life safety systems.

The 879DEX-G1 is intended for hazardous location environments such as petrochemical facilities, refineries, industrial processing plants, grain handling operations, and similar classified areas. Its supervised design integrates into fire alarm control panel notification circuits where end-of-line supervision is required. This unit is sold individually and is suited for both new construction and retrofit projects in industrial settings requiring explosion proof rated notification appliances.
