• The detection lens of the Homematic wireless
infrared motion detector operates on multiple
detection levels, each of which has 12 segments.
This means that, with an aperture angle of 90°,
a range of up to 9 m can be achieved. The total
possible detection range is illustrated in the
figure on page 37.
• To avoid the detector being triggered inad-
vertently by pets, for example, keep them away
from the detection range if at all possible. If
you cannot do this, try to align the detection
area accordingly by adjusting the height of the
detection lens.
• The effectiveness of the detection procedure
depends on the temperature difference between
the moving object and the relevant background.
• It is not possible to detect temperature diffe-
rences through glass.
• The detector responds best to movement across
the detection range, i.e. past the motion sensor.
The Homematic wireless infrared motion detector
outdoor is least sensitive to direct movement
towards or away from it.
• Select an appropriate mounting location at a
height of between 2.0 and 2.5 m.
• When mounting the wireless motion detector,
