The Werma 118.483.28 is a robust wall-mounted continuous-tone buzzer built for general signaling applications in control, facility, and industrial systems. Designed to operate directly on 230 VAC, it generates a consistent acoustic signal with an output of approximately 90 dB (A) at 1 meter — ensuring audibility in office, workshop, or light manufacturing environments. Encased in a durable grey PC/ABS housing, the buzzer features an integrated wall-mount bracket for fast, secure installation. Its flat-plug electrical connection simplifies wiring, making it easy to integrate into existing systems. The IP33 front protection rating offers limited resistance to dust and light water spray, making it best suited for indoor use. This model is particularly suitable for applications requiring continuous alerts such as machine start-up warnings, access control signaling, or process status notifications in low-noise areas.
