Installation of motion sen-
sors in order to work properly
is extremely difficult. The visu
-
alization presented here may
be helpful.
We recommend the sensor
to be tilted down, so it „sees”
only a portion of the first step.
The top of the Fresnel lens sho
-
uld be covered with an opaque
material. If the motion sensor
does not have a built-in light
sensor, at least a small, steady
source of light over the sensor
should be added to light up the
field observed by the sensor.

NOTE: The knob „Time” in the sensors must be set to the minimum position!
