The door’s movement is detected by a micro switch mounted onto a door or object with a lid. A timer provides an entry delay during which the system can be disarmed by the slide switch, whilst a separate timer silences the alarm after two minutes. Both of these timers are implemented via a 556 dual timer IC.\u003c\/p\u003e\n\u003cp\u003eThe alarm can be further enhanced by using a simple \u003ca href=\"https:\/\/kitronik.co.uk\/products\/2001-key-switch\" title=\"key switch\"\u003ekey switch\u003c\/a\u003e for arming \/ disarming or by replacing the micro switch with a \u003ca href=\"https:\/\/kitronik.co.uk\/products\/2055-magnetic-door-contact-switch\" title=\"magnetic door contact switch\"\u003emagnetic door contact switch\u003c\/a\u003e to activate it.
