The Edwards 878DEX, 879DEX, 888D and 889D Series are diode polarized, heavy-duty, high decibel, vibrating horn signals.

Two mounting brackets are provided on either side of the unit for wall mounting. The housing is tapped on one side for 3/4" (19mm) conduit to allow for field wiring installation.
