When used as a presence detector: Installation height should not be more
than 3.5 m, otherwise fine detection is not possible.
Selecting installation location
For use as a presence detector, the device is installed, for example, above a work-
place and monitors the surface below it. For use as a motion detector, the device is
installed, for example, in the hallway.
Select a vibration-free installation location. Vibrations can lead to unwanted
switching.
Avoid interference sources in the detection field. Interference sources, e.g.
heaters, ventilation, air conditioners, and cooling luminaires can lead to un-
wanted detections.
The detection field can be limited in order to minimise the influence of interfer-
ence sources. For this, use the push-on cover (see Limiting the detection field
with the push-on cover) or switch off individual sensors (see Limiting the de-
tection field).
Aligning the device
The device has three independent PIR sensors for motion detection (see figure 5).
