The Edwards B-N-8546 AC and B-8526 DC Series are designed for use where a loud and distinctive signal is needed. The sound mechanism of the signal starts and stops instantly with current impulse. The projector is connected to the heavy duty die cast aluminum housing by a cast aluminum, threaded ring.

Two mounting lugs are provided on either side of the unit for wall mounting. The housing is tapped on one side for 1/2" (13mm) conduit to allow for field wiring installation.

Used where directional sound dispersion is required or specified. Applications include timing, scheduling, paging, and general alarm at construction sites, textile and paper mills, lumber yards, and shipping docks.
