The CMR 10 Series incorporates passive Infrared (PIR) technology into an attractive and economical line powered sensor to provide maximum viewing from the ceiling. When mounted at 9 ft (2.74 m), this sensor views up to 28 ft in all directions. Its circular coverage pattern is designed for walking motions; making It ideal for T-shaped intersections in corridors or other areas where wall mounting a sensor is not practical. Low ceiling heights are also best covered with the CMR 10. For example, when mounted at only 7 ft, the height of pick aisles in many distribution centers, the CMR 10 provides a 32 ft Dia pattern of coverage, for detection of minor motion is also required, the CMR PDT 10 Series dual technology sensor is recommended.
