Designed for T5 high-bay fixture control, the CMRB-50 provides individual control of fluorescents. The sensor detects changes in the infrared energy given off by occupants as they move within its field of view. CMRB-50 features a variety of control capabilities such as low temperature/high humidity and photocell for daylight override. The sensor mounts off the end of the fixture, and once mounted, directional viewing may be altered north or south or east and west by rotating the lens turret.
