Add to Cart:

  • Units in Stock: 18
A daylight harvesting occupancy sensor which measures the Lux level in the room and adjusts the signal to the LED driver to automatically adjust the LED brightness to achieve the required LUX level.
These need connecting to LED lights with 1-10v signal dimmable drivers to allow the automated control.
The unit can be used as either a presence detector or an absence detector.
The max rated load is 1600W for resistive loads like halogen lights and 800w for capacitive loads like LED lighting.
Powers consumption less than 0.5 watts.
Maximum detection range is 6m but adjustable in intervals 10% / 50% / 70% / 100%.
The hold time which is the time the LED light is on for is adjustable to the following times 2s / 30s / 1min / 5min / 10min / 15min / 20min / 30min.
After someone leaves the room the lighting can then be dropped to a stand by level for a period of time before turning off completely.
The stand by time is adjustable to the following levels 0s / 10s / 1min / 5min / 10min / 30min / 1h and infinite.
The stand by dimming levels are 10% / 20% / 30% / 50%.
The daylight threshold is adjustable in the range 50 ~ 500Lux of this can be disabled.
TO use as an absence detector then a momentary switch in wired into the unit which is pushed to turn the lights on and then the lights will automatically turn off as programmed.
The units are best programmed using the hand held remote control HRC-11. This means that the units do not have to be removed from the ceiling or accessed for setting.
