How Does a Home Alarm System Operate?Sensors are the most vital part of the system; they act like the eyes and ears of a home alarm system by monitoring break in points and interior areas. The typical sensors, which are usually two magnets, are generally installed on doors and windows such that one magnet is connected to the door or window and the other is connected to the door or window frame. When the door or window is opened, one magnet is removed from the surrounding area of the other and the sensor registers that the door has been opened. More advanced home alarm systems may also contain vibration sensors to detect when glass has been broken by measuring the vibrations caused by the breakage. Also, many systems use motion sensors that compute the proximity of a room’s walls by producing infrared beams and measuring the time required for them to bounce back; if a beam comes back sooner than expected, it likely bounced off of a person and the sensor registers motion. When the alarm system is installed, each sensor is registered with the control panel either through wires or wirelessly. The control panel also interfaces with keypads and other input devices used by the home owner to control the system. The control center keeps track of the status of the sensors and reports activity through LCD displays and other output devices. Moreover, when activity takes places, such as the opening of a window, the sensors report the activity to the control center and the center registers that a disturbance has occurred. In managed alarm systems, the control panel also checks the sensors to verify that they are still operational; if a sensor fails to reply, the center alerts the home owner of an out of order sensor.
