The ABUS BW8080 Xevox Pet MW Motion Detector is a motion sensor with one PIR and one microwave sensor so that an alarm is not reported to the alarm centre until both sensors detect movement. The Xevox Pet MW motion detector is an animal-immune motion sensor that can tell the difference between people and small animals such as pets.
Whereas people moving in the room are reliably detected, the sensor ignores pets up to 30kg. Despite the words "pet immune to 30kg", it is possible that animals with a lower weight trigger the detector - the risk of false triggering is particularly high when the animal moves, jumps, or flies in the vicinity of the detector.
The combination of passive infrared (PIR) and microwave (MW) ensures high protection against false alarms, the reason: an alarm is not triggered until both sensors – which use technically different detection methods – register movement. Whereas the PIR sensor reacts to moving heat, the microwave sensor actively monitors the surroundings for movement (similar to radar).
The transmission frequency is 9.35GHz, while the best place to install the sensor is in a corner, between 2.4 and 2.7m above the floor. The intruder's possible direction of movement should be at right-angles to the sensor. The viewing angle of the Xevox Pet MW motion detector is 90°, and the detection range – depending on installation height – up to 12 x 12m. You can vary its sensitivity by means of a jumper, this way you can define the number of pulses that have to be detected before the sensor opens the alarm relay.

AND-connection: In case of a simple motion detector the alarm is triggered as soon as the in-built sensor detects a movement. This can sometimes lead to false alarms. For this reason, in the case of detectors with an AND-connection the two sensors are interconnected in such a way that the alarm is triggered only when all the two sensors detect a movement.
