Vibrating bells produce a long, continuous ringing sound. The striker continues to rapidly strike the gong as long as current is applied.

The bell has been designed for indoor applications requiring supervision of signaling circuit field wiring but may be used for unsupervised applications as well. Powder coat epoxy finished red.

Mounts to any solid surface using two 3/8" (10 mm) bolts and washers. Each unit is supplied with wire leads and a sealing fitting for connection to 3/4" conduit.

The 439DEX fire alarm bells are ideally suited for fire alarm appliations in refineries, gasoline storage and dispensing areas, flammable liquid areas, paint spray booths, aircraft refueling areas, granaries, flour mills, and coal mines and other combustible dust areas.
