The motion detector insert $ is mounted in a DIN 49073-compliant
device box.
The terminals of the insert must be directed downwards (wall
mounting) as otherwise malfunctions may result.
Together with the motion detector top &, the frame % is plugged
onto the insert.
An optimum detection is attained by mounting the top laterally to
the walking direction. Otherwise, a delayed detection must be
taken into account.

The mounting height generally amounts to 1.10 m.
The lens has a sensing range with an opening angle of 180 in
two levels.
The size of the sensing range amounts to approx. 12 x 12 m
related to an mounting height of 1.10 m. With other mounting
heights, the detection radius varies.
As a result of the right-angled adjustment of the upper lens level,
the sensing range is not subject to spatial limitations. Therefore,
even motions outside the defined sensing range may initiate
switching operations under certain circumstances (overreach).
Note: due to the almost horizontal adjustment of the upper sensing
level, the motion detector tops equipped with the 1.10 m lens
are basically suitable for indoor use only. If mounted in outdoor
areas, the sensore may be irreparably damaged by direct sunshine.
