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.
