Installing the PIR Detector
Positioning the PIR
●
Position the Wirefree PIR Detector within
range of the Receiver, taking into consideration
any reduction in the 200m maximum range
caused by any objects in between. Avoid
mounting the unit on or near large metal
objects.
●
The recommended mounting height for
the detector is 2.5m. At this height, the
detector will have a range of approximately
12m. Mounting the detector higher will
increase the detection range but it will be
less sensitive to movement at the
extreme range and also may not be able
to detect movement very close to it.
Tilting the detector head up and down
will have the same effect.
●
Mount the detector on a firm stable
surface where the logical path of a
person would cut across the detection
pattern. The detector is more sensitive
to movement across its detection pattern
than to movement directly towards it.
