c) Installing the ‘FAZ 3000-PIR-2’ PIR motion detector
One ‘FAZ 3000-PIR-2’ passive PIR motion detector is included in the set. Additional
detectors may be purchased separately.
1. Installation notes
• The detection lens of the ‘FAZ 3000-PIR-2’
passive PIR motion detector has 4 detection
levels with 9 upper, 8 middle and 5 lower
segments, as well as 2 additional creep zone
segments.
The main sensor at the front can attain a range
of up to 12m at a detection angle of 90°.
Please be aware that the detection area is
determined by the installation height of the motion
detector, as well as the adjustment of the lens
opening.
Therefore, the diagram on the right is only
intended as an example for the lens optics.
When mounted in a bracket the sensor can be
turned approx. 45°, which makes it easier to
adjust the detection area later on.
Figures 24 & 25
• For additional security, the PIR motion detector is equipped with so-called ‘creep protection’
so that an intruder cannot ‘creep’ under the detection area of the main lens. The creep zone
protection comprises an additional lens on the underside of the PIR motion detector which
is directed downwards. This mini dome lens with 17 segments covers an area of approx.
3.75m x 3.75m when the PIR motion detector is installed at a height of 2m.
A larger area can, of course, be covered, when the PIR motion detector is installed higher
up.
• In order to avoid household pets from setting off a false alarm, keep them away from protected
areas when possible. If this is not possible, try to change the detection area by adjusting
the height of the circuit board in the PIR motion detector.
If necessary, cover the creep zone protection or individual parts of the lenses. To do this
you can use non-transparent insulating tape. Bear in mind that household pets can also jump
up onto cupboards or chairs, for example, and can thus enter the detection area and activate
the motion detector.
• Select a suitable installation location, according to the local conditions, at a height of approx.
1.8m to 2m; if necessary, this can also be higher or lower.
