This Office Call Bell Network Circuit with LED Monitor is a system designed for offices to communicate with each other easily. It consists of three identical modules containing two NPN transistors.

Electrical and Electronics How Does A Calling Bell Work?

The circuit implementation of the proposed office call bell monitor network can be done by using a group of set/reset flipflops as may be witnessed in the following diagram: Circuit Diagram. The circuit above illustrates an example wiring for three office rooms which may be extended to any desired numbers simply replicating the stages. How it Works

Electric Bell Circuit Diagram

Let's Build our Simple Tone Generator. Here we present a simple and low-cost tone generator circuit, a ding dong bell suitable for calling bell purposes. It is made around IC 8021. It is an 8 pin IC but only four pins are shown here. 8021 has an in-built circuitry to produce ding dong sound each time its pin 3 is pulled low.

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.
