Door Ajar Alarm Circuit electroschematics In this door ajar alarm beeper circuit, a bar magnet reed switch combination is used as the door sensor. When the door is closed, as per mechanical arrangement, the bar magnet near the reed switch close its switch contacts. Now the beeper circuit built around CD4011 (IC1) is disabled by the logic low state at its input terminals (pins 1&12). Door Ajar Alarm Circuit Engineering Projects Circuit Description of Door Ajar Alarm Circuit. The heart of the circuit is 14 stage ripple carry binary counter IC CD4060. The working principle of the circuit is very simple, when high input at reset pin (pin 12) is given all the output becomes low and vice versa. Door Ajar Alarm Circuit – Circuit Wiring Diagrams In this door ajar alarm beeper circuit, a bar magnet reed switch combination is used as the door sensor. When the door is closed, as per mechanical arrangement, the bar magnet near the reed switch close its switch contacts. Now the beeper circuit built around CD4011 (IC1) is disabled by the logic low state at its input terminals (pins 1&12). Door ajar alarm_Circuit Diagram World Door ajar alarm can senses to the door ajar. If the door ajar longer than 20 seconds, the alarm will beep alarm.
