The ABUS motion detector has a PIR and microwave sensor. The combination of passive infrared (PIR) and microwave (MW) provides high security against false alarms. An alarm is triggered only when both sensors with separate detection methods detect a movement. The PIR sensor reacts to moving heat, the microwave sensor actively monitors the environment (Doppler effect). With the MW transmission frequency of 24.15 GHz, the detector can be used in all EU countries. Optionally, only one type of monitoring can be activated.

Passive infrared motion detector (PIR) with microwave element (MW) for indoor use
Dual detector: PIR sensor and MW sensor combined in one detector
Pet-immune optional: Ignores animals up to approx. 15 kg
Monitors entire rooms (detection area approx. 12 x 12 m)
Microwave frequency in the 24 GHz range (EU-wide approval)
No blind spots thanks to anti-creep protection
AND- or OR-linked PIR and microwave element
Time-saving installation thanks to preconfigured, common resistor combinations for alarm and tamper monitoring on the detector, conveniently adjustable via jumpers (plug-in jumpers)
