Model 350WBX (AC current) Vibratone® horn produces sound by the electro-mechanical vibration of a stainless steel diaphragm. The horn mechanism with diaphragm is attached to the grille. The water- and dust-tight backbox is ideal for indoor or outdoor use.
The Model 350WBX is available in 120 or 240VAC for 50/60Hz. Its sound output level is 100dBa nominal at ten feet (110dBa @ 1 meter).
This hazardous location horn accommodates surface, flush or semi-flush mounting on walls, panels, in cabinets.
The Model 350WBX features a die-cast zinc housing with a corrosion-resistant polyurethane finish. The rugged outer grille resists vandalism without reducing sound output. The 350WBX is fused and utilizes a terminal block connection. The 350WBX is approved for Class I, Division 2, Groups A, B, C and D; Class II, Division 2, Groups F and G; and Class III.
Capable of producing coded blasts or sustained tones, Federal Signal's Vibratone horns are excellent for general alarm, start/dismissal, coded paging and process control signaling in areas where their sound output exceeds ambient noise levels. Compact size and a variety of installation options make them ideal for institutional use.
