1: Range for tangential movement on the ground
2: Range for radial movement on the ground
3: Range for typical movements at desks, e.g. torso movement
4: Range of fine detection at desks, e.g. mouse movements
*) 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 workplace 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 area. Interference sources can trigger the mo-
tion detector, e.g. heat sources such as heating units, outlets from ventilation openings or
air conditioners, copiers, printers, coffee machines, draughty doorways, animals etc.
The detection field can be limited in order to minimise the influence of interference
sources. For this, use the push-on cover (see Limiting the detection field using the push-
on cover) or switch off individual sensors (see Configuring device settings).
Aligning cover
The device has three independent sensors for motion detection. The arrangement of the areas
A, B and C is clearly evident under the decor ring (Figure 4).
