Vibratone® Horn produces a very loud horn tone by the electro-mechanical vibration of a diaphragm. Capable of reproducing coded blasts or sustained tones through the use of a number of control devices from a push button to a PLC. Vibratone® horn is excellent for general alarm, start and dismissal, coded paging and process control signalling in areas of high ambient noise levels. Vibratone® 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. A double projector accessory mounted on the front of the unit directs side sound output, optimizing signalling for long, narrow rooms or corridors. The Vibratone® 350 horn is enclosed in a zinc die-cast housing and sealed with grey powder-coat paint and features a stainless steel diaphragm. The rugged construction of the Vibratone® horn resists vandalism and the effects of harsh industrial environments. Compact size, loud output and heavy-duty construction make the 350 horn ideal for industrial and institutional signalling applications.
