The device has a detection area of 360°. The diameter of the detection area depends on the
installation height and the direction of motions of persons in the detection area (Figure 4).
The detection area becomes larger the greater the installation height, while the detection
density and sensitivity are reduced at the same time.

When used as a presence detector: Installation height should not be more than 3.5 m,
otherwise fine detection is not possible.
Selecting the installation location
For use as a presence detector, the device is installed, for example, above a workplace and
monitors the surface below it. For use as a motion detector, the device is installed, for example,
in the hallway.
o
Select a vibration-free installation location. Vibrations can lead to unwanted switching.
o
Avoid interference sources in the detection area. Interference sources, e.g. heaters,
ventilation, air conditioners, and cooling light bulbs can lead to unwanted detections.
