Mounting
The eectiveness of the detection procedure
depends on the temperature dierence between
the moving object and the relevant background.
It is not possible to detect temperature dierences
through glass.
The detector responds best to movement across
the detection range, i.e. past the motion
detector. The device is least sensitive to direct
movement towards or away from it.
When mounting the motion detector, please
ensure that it is not installed directly on or in the
vicinity of large metal objects (heaters,
aluminium clad walls, etc.), as this would reduce
the wireless range.
To reduce the risk of a false alarm being
triggered, the motion detector must not be
exposed to direct sunlight, car headlights, etc.,
nor must it be mounted in the vicinity of a heat
source (above a heating appliance, for example).
The detection ranges must be aligned against a
wall or the floor, but not directly on a window,
heater or other heat source.
