Horns
Vibrating
870EX Series
The 870EX Series vibrating horns are heavy-duty,
explosion-proof, high decibel horns designed for
use in hazardous locations.
Diode polarized versions are also available. They
are intended for use in hazardous locations
requiring electrical supervision of signaling circuit
field wiring. May also be used for unsupervised
signaling applications.
Two mounting brackets are provided on either
side of the unit for wall mounting. The housing is
tapped on one side for 3/4" conduit to allow for
field wiring installation.
