In the case of larger rooms, it may be necessary to use several Presence Detectors. The
detection ranges should overlap approx. 0.5 m - referred to an "Operating height" of 1 m.
When installing as a constant light controller, care must be taken that only reflected daylight
and constant light are detected.

4.3 Adjustment of the Detection Range

A pre-punched masking strip, which can be affixed to the four-element lens, is supplied with
the Presence Detector. This masking strip is divided into wide and medium/close-range
segments. Prior to installing the device, proceed as follows:
• Before peeling it off the backing, cut the masking strip,
if necessary, to suit the circumstances prevailing in the
room.
• Peel the masking strip off in segments.
• Carefully affix the masking strip to the area to be
masked. Ensure that the area to be masked is com-
pletely covered.
