The Edwards hazardous location fire bell stands out as the premier heavy-duty bell designed for hazardous environments currently on the market. It produces a unique, crisp sound devoid of mechanical noise. Unlike vibrating bells, which emit a prolonged, continuous tone, this bell's striker rapidly hits the gong as long as power is supplied. It is specifically engineered for indoor settings that necessitate oversight of signaling circuit field wiring, though it can also be utilized in unsupervised scenarios. Finished in a durable powder-coated epoxy red, it can be mounted on any solid surface using two 3/8" (10 mm) bolts and washers. Each unit comes equipped with wire leads and a sealing fitting for connection to a 3/4" conduit. The 439DEX fire alarm bells are perfectly suited for fire alarm systems in refineries, gasoline storage and dispensing areas, flammable liquid zones, paint spray booths, aircraft refueling sites, granaries, flour mills, coal mines, and other areas prone to combustible dust.
