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.
