Product Details
The Edwards hazardous location fire bell, available in 6", 8", and 7" gong sizes, features low power drain for efficient operation over long wire runs and an adjustment-free self-compensating plunger, ensuring reliable performance. Constructed to be corrosion-resistant, this heavy-duty bell delivers a distinctive, clear ring free of mechanical clatter, producing a long, continuous ringing sound through its vibrating mechanism, with the striker rapidly striking the gong as long as current is applied. Designed for indoor applications requiring supervision of signaling circuit field wiring, it can also be utilized for unsupervised applications. The bell comes with a powder coat epoxy finished in red and mounts to any solid surface using two 3/8" (7 mm) bolts and washers. Each unit is equipped with wire leads and a sealing fitting for connection to 3/4" conduit. The 439DEX fire alarm bells are ideally suited for fire alarm applications in refineries, gasoline storage and dispensing areas, flammable liquid areas, paint spray booths, aircraft refueling areas, granaries, flour mills, coal mines, and other combustible dust areas.
