If possible, the Presence Detector should be mounted directly above the workplace in each
case. The recommended mounting height is 2.5 m. With mounting heights > 2.5 m, the
detection range increases - at the same time, the detection density and sensitivity are
reduced.
The distance to the lighting should, in the case of lamps which generate a high degree of heat,
be at least 1.5 m. High objects such as, e.g., movable partitions in open-plan offices, can
reduce the detection range; an additional Presence Detector should be installed if necessary.
In the case of larger rooms, it may be necessary to use several Presence Detectors. The
detection ranges should overlap by approx. 0.5 m (see Master/Slave Mode, Chapter 6.2).
4.3 Adjustment of the Detection Range by means of the Masking strip
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.
