Sources of interference
Moving heating air
Fig. 35: Movement detector malfunction source: moving heating air
Movement detectors react to infrared radiation (heat radiation). If the movement detector is
located in an area where warm air moves strongly, this can lead to undesired switching
operations of the movement detector. Such an area is e.g. above a heating system.
Place the movement detector in an area where the movement detector is not affected.
Open doors
Fig. 36: Movement detector malfunction source: open door
If the movement detector's detection range runs through an open door, this will result in
switching operations if a person crosses this range.
In this example, placing the movement detector opposite on the adjacent corridor wall would be
more suitable.
