Overview
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.
