The RM-10 Series incorporates Passive Infrared (PIR) technology into an attractive sensor that recess mounts into a 4 x 4 junction box. When mounted at 9 feet, this sensor views up to 28 feet in all directions. Its circular coverage pattern is 56 feet in diameter and 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. A long hallway for example may require a HW-13 Series Hallway sensor at each end, with RM-10s mounted in the center to fill in the distance. Low ceiling heights are also best covered by the RM-10. For example, when mounted at only 7 feet, the height of pick aisles in many distribution centers, the RM-10 provides a 32 foot diameter pattern of coverage. In applications where detection of minor motion is also required, use the RM-PDT-10 Series Dual Technology sensor.
