Principle Behind This Calling Bell Circuit. This circuit chiefly comprises two 555 timer clock ICs. First IC is worked in astable mode and the frequency of the second IC is tweaked by the first IC. For that, the output pin of the first IC is associated with the fifth pin of the second IC. The first IC is worked at a frequency of 1Hz.

Fig. 3: Circuit diagram for Multi-User Call Bell. Working of the circuit is simple. When, say, room number 1's switch S1 is turned on, its LED1 glows and DIS1 displays 1 besides sounding an alarm through piezo buzzer PZ1. The caller should switch off S1 after the call has been attended so that the system is ready to receive the next call. Fig.
