Working Explanation

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, one PNP transistor, and a few resistors.

The “ON” button is used to turn on the bell in the respective room, while the “OFF” button turns it off. When a positive voltage is applied to the collector of the PNP transistor, the bell in that specific room is triggered.

The triggered signal is then sent to the head office, where a relay driver circuit system is set up. The relay is activated, and the bell starts ringing. The person in the room presses the green button, which turns off the bell and lights up the corresponding red LED in the head office circuit, indicating the location of the member who responded to the call. The red LED can be reset by pressing the reset button in the head office circuit.

Final Words

The Office Call Bell Network Circuit with LED Monitor is helpful for large offices or workplaces. It helps in quickly and easily communicating with employees in different rooms.

The circuit is easy to set up and can be customized to accommodate many rooms. The use of transistors, push buttons, and LEDs make the circuit both reliable and user-friendly. Try this circuit, and for any query, feel free to use the comment section. Happy building!
