The ABUS BW8040 Xevox Triplex MW VdS Motion Detector is a motion sensor with two PIR sensors and one microwave element. An alarm is not triggered until all sensors detect movement.
The combination of microwave (MW) and two passive infrared (PIR) sensors ensures almost 100% protection against false alarms, the reason: an alarm is not triggered until all sensors – which use two technically different detection methods – register movement. Whereas the PIR sensors react to moving heat, the microwave sensor actively monitors its surroundings for movement - the transmission frequency is 9.35GHz.
The best place to install the sensor is in a corner, between 2 and 3m above the floor, while the intruder's possible direction of movement should be at right-angles to the sensor. The viewing angle of the Xevox Triplex MW VdS motion detector sensor is 90°, and the detection range - depending on installation height - up to 15 x 15m. 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.
The Xevox Triplex MW VdS motion detector sensor has an alarm memory - if the alarm center is disarmed following an alarm, the LED on the sensor that triggered the alarm lights up. Depending on the configuration, you can also see which sensor first triggered the alarm. Due to its reliability and high quality, the Xevox Triplex MW VdS motion detector sensor is VdS-certified.

Triplex 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 a Triplex-connection the three sensors are interconnected in such a way that the alarm is triggered only when all the three sensors detect a movement.
