.1 Presence detection
The ideal mounting height is 2,0 - 3,5m. The sensitivity of the detector de-
creases with increasing mounting height. The detection ranges of multiple
detectors should overlap in their fringe zone. Ensure the horizontal installa-
tion of the detector.
Because of the virtually horizontal detection of compact passage to both
directions, the detection range of tangential (t) movements of persons is
different to the range of radial (r) movements towards the detector.
