But if somebody opens the door, the circuit is opened, and electrical energy can not flow. This triggers an alarm. In an open-circuit system, opening the door closes the circuit, so electricity begins to flow. Also in this method, The Alarm is triggered when the circuit is completed. Magnetic sensor A magnetic sensor in a closed circuit consists of a handful of basic elements. - a battery powering a circuit - a spring-driven metal switch built into a door frame  - a magnet embedded in the door, lined up with the switch  - a separately-powered buzzer with a relay-driven switch.
