Signalling Bell
Corrosion-resistant signalling device for indoor and outdoor use

• Multi-stroke and single-stroke signalling bell
• Slow-stroke signalling bell with adjustable stroke rate between 200/min. and 30/min.
• Various flat domes

The signalling bells are used for clear calling, reporting and warning purposes as a high-pitched bell sound stands out clearly against ambient noise. Different dome sizes enable ideal signalling. The drive system of the multi-stroke signalling bell consists of a single-coil electromagnet. In the AC variant a diode in the circuit enables a current flow in half period, so that the striker oscillates in time with the supply frequency. The DC types are equipped with a non-wearing electronic contact breaker. The stroke rate is approx. 50 strokes/sec.

The AW 1 multi-stroke AC versions work with half-wave DC current. The contact-breaker system in the AW 2 DC versions produces an intermittent direct current. Thus, when planning the supply lines and fuses, it should be considered that the given values are mean current values and the peaks are higher. The correct polarity of the connection line must be observed.

The Single-stroke Bells AW 3 and AW 4 are each equipped with an electromagnet system that drives the striker against the bell dome only once per current-on transition. The maximum permissible duty cycle is 5 min.
