Acuity Sensor Switch RMR 10 alarm system PIR 2463 sq ft White

Occupancy Sensor for Large Areas

The Acuity Sensor Switch RMR 10 is a passive infrared occupancy sensor designed for ceiling installation in commercial or residential spaces. It provides motion-sensing and dimming control for lighting circuits across a coverage area of 2463 sq ft at the suggested mounting height. The unit operates on hard-wired 120V AC or 277V AC supplies, making it suitable for standard building electrical systems. It targets installers who need automated lighting control in open-plan rooms.

White Finish and Adaptive Time Delay

The sensor features a white housing that blends with typical ceiling surfaces. Its time delay is adjustable from 30 sec to 20 min using an adaptive method that learns occupancy patterns, with a manual override option also available. The hard-wired communication method means the device connects directly to the lighting circuit without wireless pairing steps. This suits electricians who prefer a permanent, interference-free installation.

PIR Coverage and Voltage Limits

Passive infrared technology detects heat movement within the stated 2463 sq ft zone, so obstacles or high partitions can reduce effective coverage. The sensor only supports 120V AC and 277V AC inputs; other voltages are not compatible. Buyers needing wireless configuration, multi-zone control, or operation on low-voltage DC systems should look elsewhere.
