Werma 645 Series Buzzer Unit, 24 V dc, AC, DC, IP65

Use this WERMA buzzer element to provide an effective warning signal in your industrial or commercial workspace. It offers a loud sound output of up to 85dB (decibels), ensuring it's clearly audible even in noisy environments. For versatility, you can choose between a continuous tone or a pulsing sound. The buzzer can act alone with a termination block as a purely audible warning signal, or you can pair it with visual signals from the KombiSIGN 71 series to create a customised signal tower. It's simple to mount this unit on a variety of different bases, giving you flexibility when setting up your warning system.
