Vibratone® Horns produce 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. Each Vibratone® horn is enclosed in a zinc die-cast housing and sealed with grey powder-coat paint. The Model 450 utilizes an aluminium diaphragm and heavy duty contacts. The rugged construction of the Vibratone® horns resists vandalism and the effects of harsh industrial environments. Compact size, loud output and heavy-duty construction make the VibraTone horns ideal for industrial and institutional signalling applications.
