{"product_id":"kitronik-alarm-project-kit","title":"Kitronik Alarm Project Kit","description":"\u003cp\u003eThis kit can be used to make a shed or room alarm when mounted on the top of a door, drawers or any other object with a moveable opening. It can also be used by replacing the micro switch with a magnetic door contact.\u003c\/p\u003e\n\u003cp\u003eA micro switch acts as a trigger mechanism and is armed \/ disarmed by a seperate sliding switch. 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 title=\"key switch\" href=\"https:\/\/kitronik.co.uk\/products\/2001-key-switch\"\u003ekey switch\u003c\/a\u003e for arming \/ disarming or by replacing the micro switch with a \u003ca title=\"magnetic door contact switch\" href=\"https:\/\/kitronik.co.uk\/products\/2055-magnetic-door-contact-switch\"\u003emagnetic door contact switch\u003c\/a\u003e to activate it.
