ACUITY 184F4A 120-277V CMR ADC Series Automatic Dimming Control Photo Sensor - Ceiling Mount Low Voltage, White

The CMR(B)-ADC Series of Automatic Dimming Control sensors provide continuous control of dimmable ballasts for daylight harvesting applications. Ideal for public spaces with windows like vestibules, corridors, or bathrooms; the CMR(B)-ADC works by monitoring daylight conditions in a room, then controlling a 0-10 VDC dimmable ballast so as to insure that adequate lighting levels are maintained. The CMR(B)-ADC sensors are line powered and therefore do not require a Power Pack. The CMR version sensors are ceiling mounted, while the CMRB versions are specifically designed to mount on the end of a linear fluorescent fixture. To add full On/Off switching to the dimming control provided by the CMR(B)-ADC sensor.FEATURES:• Line Powered, no Power Pack needed• Digital Set-Point Control• Programmable via simple Push-button commands• Dimming sinks up to 20 mA• Green LED Activity Indicator• 100 Hr Lamp Burn-in Timer Mode
