5.2.1 Selection of installation place
The PIR lens of the device can be rotated variably in an angle of 360°, and tilted.
Observe the following preconditions for selecting a suitable installation place:
• Weatherproof, free from direct sun radiation, other heat sources, and car head-
light beams.
• The detection range is up to 12 metres. The detection angle is 90°. The figure
shows the full detection range (see fig 3 page 3).
• Recommended installation height: approx. 2 to 2.5 m
• Unintended triggering caused by pets cannot be excluded. In order to reduce
that risk, align the detection range by varying the height of the detection lens.
• Please observe the general safety notes (see „Safety notes“ page 23).
• The detection performance depends on the temperature difference between
the moving object and the respective background. It is impossible to detect
temperature differences through glass panes.
• The highest sensitivity is reached by a movement in transversal direction
through the detection range. Direct movement towards the motion sensor or
from the sensor away will result in the lowest sensitivity.
