Abus Wired PIR, duplex
Wired motion sensor with a PIR and a microwave sensor. An alarm is only triggered when both sensors detect a movement and there is great security against false alarms. While the PIR sensor responds to heat moving against it, the microwave sensor (like a radar) actively monitors the area of motion. The transmission frequency is 9.35 GHz. The optimal mounting location is directly in a corner, between 2-3 m above the floor. The possible direction of movement for an intruder should go across the detector. The angle of view of the motion sensor is 90 degrees and the detection range - depending on the mounting height - is up to 15 x 15 m. The sensitivity can be adjusted.
