The 2.20 m lens
Mode of operation of the 2.20 m lens
Sensing range of the 2.20 m lens
The lens has three ranges of sensing levels, so that the sensing range is
divided into near, medium and distant range.
The sensing levels of the 2.20 m lens arranged from the top to the bottom
The mounting height generally amounts to 2.20 or 1.10 m.
If a mounting height higher than 2.20 m is selected, please note
that under certain circumstances the energy radiated by a more
distant heat
signal source is not sufficient to release the motion
detector top.
The lens has a sensing range with an opening angle of 180° in
three levels. The three levels are directed from top to bottom.
The size of the sensing range equals
• For a mounting height of 2.20 m: approx. 12 m x 12 m
• For an mounting height of 1.10 m: approx. 6 m x 6 m
Avoidance of sources of interference
In order to avoid unintended switching operations, the following
instructions should be complied with during installation:
• As a result of the thermal radiation from the lighting or an in-
sufficient distance between the motion detector and the lamp,
an undefined switch-on operation may be initiated.
• When selecting the mounting location, it should be ensured
that no sources of interference, e.g. lamps or heaters are po-
sitioned within the sensing field. If this is not possible, a plug-
on blind should be used.
Use of the plug-on blind
Using the plug-on blind, sources of interference can be sup-
pressed by narrowing the sensing range. The blind covers 90°
of the left or right sensing range.
