Switching Detectors with Lux Level Sensing

These presence detectors have built-in adjustable lux sensors which will keep the lighting switched off if there is sufficient natural light.

All ceiling mounted PRM detectors can be set up from ground level using our simple programming handsets. A time delay can be set to avoid nuisance switching with constantly varying lux levels.
