Hazardous location DC single stroke bells produce a distinctive, loud,
and clear individual note that is free of mechanical clatter. When cur-
rent is applied, the striker hits the gong once and stops. Current may
be coded to cause the striker to hit the gong intermittently. Ideal for
use with momentary initiating contacts.
Mounts to any solid surface using 3/8" (10mm) fasteners. Units fitted
with a sealing fitting for 3/4" (19mm) conduit and wire leads for power
connections.
Used for coded signal applications such as paging. Also specified for
timing, scheduling, and general alarm applications in refineries,
gasoline storage and dispensing areas, petrochemical manufacturers,
spray paint areas, aircraft hangers, grain dust areas in graineries and
flour mills, and industrial firms using flammable liquids.
