The Model B-874-120 Vibrating Horn produces a very loud horn tone through the electro-mechanical vibration of a diaphragm.  Capable of reproducing coded blasts of sustained tones, Bridgeport's Vibrating Horns are excellent for general alarm, start and dismissal, coded paging, and process control signaling in areas of high ambient noise levels.  The unit produces 100db @ 10 feet.

Mounting options provide for surface, flush or semi-flush mounting on walls, panels, in cabinets, on 4-inch square outlet boxes, or in concrete and deep wall constructions.

Each Vibrating Horn is enclosed in a zinc die-cast housing and sealed with gray powder-coat paint.  The unit features a stainless steel diaphragm.  The rugged construction of Bridgeport's horns resists vandalism and the effects of harsh industrial environments.

Compact size, loud output and heavy-duty construction make Bridgeport's horns ideal for industrial and institutional signaling applications.
