The detector is used for human motion detection in the interior of a building. Thanks to the combination of motion and microwave detection, the detector is highly resistant to false alarms. When motion is sensed by the PIR detector, the MW detector is activated to confi rm the triggering of the PIR. Only after receiving a confi rmed alarm signal from the MW unit, the detector sends an alarm report to the control panel. The detection characteristic may be optimised by using alternative lenses JS-7904 LONG HALLWAY, JS 7906 PET or JS-7901 CURTAIN. It is addressable and occupies one position in the alarm.
