Setting the motion sensors
This is one of the most difficult operations — it requires patience and precision. First of all, adjust
the sensitivity of the sensor in order to have it react effectively to a person entering the staircase. The
second problem to solve is that the sensor should not react to a person coming down the stairs - that it
does not re-activate the fading lighting of the stairs. The best way is to cover the sensor hemispheres
respectively. Of course, the arrangement of the sensors is also very important — usually they are
placed on the right side of the stairs looking in the direction of movement (‘right-hand traffic’). Some
sensors have an additional adjustable parameter - the so-called ‘dead time’. It is the time measured
after an impulse, during which the sensor does not respond to the next person entering the field
of its operations. When the mentioned parameters are adjusted patiently, the sensors will function
properly, providing a satisfactory lighting of the stairs.
