The Model 350WB Vibraton horn produces sound by the electro‑mechanical vibration of a stainless steel diaphragm. The horn mechanism with diaphragm is attached to the grille. Indoor or outdoor use is made possible by the water and dust tight backbox.
Model 350WB Vibratone features die‑cast aluminum rear housing sealed with a gray enamel finish. The rugged outer housing resists vandalism without reducing sound output. Model 350WB Vibratone is fused and utilizes a terminal block connection.
