When deciding on the height of the mounting site, remember to
take the possible blind spot into consideration. The blind spot
underneath the device enlarges proportionally to the height of the
mounting site.
Mount the sensor:
o
In a position such that an intruder would normally move across
the PIR’s field of view.
o
In a corner to give the widest view.
o
Where its field of view will not be obstructed e.g. by curtains,
ornaments etc.
o
For a small 3 to 5m room, install between 1.9 to 2m above
ground.
If you have pets, for the best performance of the sensor,
remember to adapt the mounting height of the sensor to the
height of the tallest animal.
Mount where the animals cannot come to the detection area by
climbing on furniture or other objects.
Don’t aim the detector at stairways the animals can climb on.
Suitable location: restrictions
Do not position a pir to look directly at a door protected by a door
contact. This could cause the door contact and pir radio signals to
be transmitted at the same instant when entering, cancelling each
other out.
Do not install the PIR completely exposed to direct sunlight.
Avoid installing the PIR in areas where devices may cause rapid
change of temperature in the detection area, i.e. air conditioner,
heaters, etc.
Avoid large obstacles in the detection area.
Do not point the sensor directly at heat sources , for example a
fireplace, boiler, and not above radiators.
Avoid pointing the sensor to an area with moving objects, for
example curtains, etc.
