Components of burglar alarm systems
The basic elements that make up a burglar alarm system are the sensors, control panel and siren.
Control Panel: This is often termed as the 'brain' of the system. It houses the processor, the communication modules and the back-up battery. It needs a constant supply of power. It monitors the sensors. When the sensor sends signals to the control panel and the alarm is armed, it sounds the siren. You can select zones that you wish to monitor and free zones that d not need monitoring.
Siren: This is the audible part of the burglar alarm system which is responsible for alerting the home owners about an intrusion. The siren is sounded when it receives a signal from the control panel to do so. The triggering of the sensors alerts the control panel. The siren needs a constant supply of power. It should be installed high up so that it cannot be tampered with. The piercing sound of the siren deters burglars and causes panic.
Sensors: There are different types of sensors that are available in the market. For instance a passive infrared sensor is capable of detecting body heat or movement. There are door or window sensors which can detect the opening and closing of doors or windows. There are shock sensors also which can detect a strike.
