Alarm Sensors are the devices which detects/Senses any intrusion and sends signal to the control panel which in turn activates alarm and informs the concerned people about the intrusion.Some of most commonly used sensors for burglar alarm are listed below.
Surface Mount Switch:
These are the switches that sense the opening or closing of a door or window. The switch is mounted to the surface of a door or window, the switch has a contact, which is closed by magnetic field generated by magnet. When the door or window moves away from the magnet, the switch opens and it is sensed by the alarm control panel.
Recessed Mount Switch:
These are the switches that sense the opening or closing of a door or window. The switch and the magnet are recessed into the door or window. A small, usually circular hole is drilled into the door or window frame and in a corresponding point on the door or window. When the door or window moves away from the magnet, the switch opens and it is sensed by the alarm control panel.
Shutter Switch:
Shutter switch are used for supervising opening of garage shutter. The switch has got a contact, which is closed by magnetic field generated by magnet. If one of the elements is moved away from the other one, then, information is transmitted on to the alarm control panel.
PIR Motion Detector:
PIR can detect movement or motion in a large room. It detects Movement by sensing infrared radiation, and in addition, by using microwaves.
Panic Switch:
It is used to send an immediate, discreet alarm/call for help up on the press of a Switch during emergency situations.
Vibration Sensor:
The Sensor helps in detecting an intruder that is using force to pound through a wall, roof or other area of the structure.
Glass Break Detectors:
The detectors are designed to constantly listen for the sound of breaking glass. When it detects sound pattern of glass break it sends signal to alarm control panel.
Beam Sensor:
It consists of two separate components: a transmitter and a receiver. The light beams only travel one way (from the transmitter to the receiver).when the lights beams are obstructed by an intruder, it signals the alarm control panel.
Boundary Detector:
It detects the intruder and signals the alarm control panel whenever your property’s boundary is compromised. Boundary Detector creates a multi-layered, horizontal barrier that detects intruders.
