The Federal Signal 350-120-30 Vibratone Horn is a compact, heavy-duty electronic horn designed to deliver loud, clear signaling in industrial and institutional environments. Operating at 120 VAC, this horn produces a sound level of 100 dBA at 10 feet (110 dBA at 1 meter), ensuring audibility even in high ambient noise conditions. Its electro-mechanical diaphragm vibration mechanism allows for both coded and sustained tones, making it versatile for various signaling applications such as general alarms, start and dismissal notices, coded paging, and process control signaling. The horn is housed in a durable zinc die-cast enclosure with a gray powder-coated finish, providing resistance to harsh environments and potential vandalism. Mounting options include surface, flush, or semi-flush installations on walls, panels, cabinets, 4-inch square outlet boxes, or in concrete and deep wall constructions. When installed with the optional panel mount gasket kit or weatherproof back box (Model WB), the horn achieves a Type 4X enclosure rating, suitable for wet and corrosive environments. With an operating temperature range of -65°F to 150°F, the 350-120-30 is built to withstand extreme conditions, ensuring reliable performance across diverse operational settings.
