The detection of an intrusion attempt occurs only when both IR sensors are
stimulated. Figure 2 graphically summarizes how the detector operates.
Sensors can be horizontally adjusted from 45 to 135 degrees. The detection area is
set to 90 degrees and it can be masked. The coverage area of the lower sensor can
be vertically adjusted.
Figure 3 shows the coverage diagram (side view) for the 5 sensor inclination
positions when the detector is positioned at 1 meter height.
WARNING! The coverage distance of the detector is defined by the
coverage provided by the lower IR sensor.
