Detection Range Adjustment
Slide the moving PIR to the desired
position, see figure 6.
The range of the lower detection area
determines the detection range.
The upper PIR is fixed and its detection
area is parallel to the ground at all times.
The lower detection area changes from
2m to 12m depending on the location of
the moving PIR. Therefore, the detection
range is established according to the
location of the lower PIR since both the
upper and the lower PIR should be
triggered in order to activate an alarm.
