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).
