The CMRB-PC-ADC Series combines the CMRB-PC On/Off Photocell sensor with the CMRB-ADC Automatic Dimming Control sensor to provide the industrys most intelligent control of lighting for daylight harvesting applications. Ideal for public spaces with windows like vestibules, corridors, or bathrooms; the sensors work by monitoring daylight conditions in a room, then controlling the lighting so as to insure that adequate lighting levels are maintained. The CMRB-PC-ADC Series sensors are line powered and can switch loads directly without the need for a Power Pack. The CMRB-PC-ADCs enclosure is specifically designed to mount on the end of a linear fluorescent fixture.
