The GRAPHITE passive infrared detector detects movement in a protected area. The large coverage area (over 100 m2) has been achieved owing to the patented geometry of Fresnel lenses. Hence, fewer detectors are needed for effective protection, installation is simple, and investment costs are low.

Operation of the device is based on a digital motion detection algorithm. Digital temperature compensation ensures effectiveness of the detection by adjusting sensitivity to the temperature in the room. The sensitivity of detection is continuously adjustable, hence parameters of the detector can be adjusted precisely to the size of the room and the conditions prevailing in it.

A useful solution is switching remotely on/off the violation indicating LED (without opening the detector enclosure). As a result, the LED can be turned on e.g. when testing the alarm system, and turned off in the normal operation mode so as to make the detector less conspicuous.

The alarm memory signaling function allows you to check which of the detectors has initiated alarm, without having to watch the state of the control panel. Security of the detector operation is provided by monitoring the signal path and power supply as well as the tamper switch.
