To make the best use of the systems, all areas should be surveyed for suitability. Using the wrong type of controls is another common error. Variable lighting control systems only work in a narrow range of applications that can make use of available daylight. Trying to use them in other applications will result in building occupants bypassing the system. Care must be taken when selecting occupancy sensors.
Different systems have different ranges of coverage.
Trying to use one that does not provide adequate coverage for the area will result in the system switching the lights off while the area is occupied. Using one that is too sensitive will result in the system turning the lights on when the area is unoccupied. Equally important is proper location of the sensor. Sensors cannot see around corners or through furniture. They must be placed properly if they are to sense occupancy accurately.
