The Sensorswitch CMR 9 is a ceiling mount passive infrared (PIR) occupancy sensor designed for standard-range coverage in commercial and institutional spaces. Ideal for offices, classrooms, corridors, and open-plan work areas, it automatically controls lighting based on occupancy — reducing energy waste without requiring manual switching. The compact, low-profile design installs easily into a 3.5" octagon box, ceiling tile surface, or single gang box, making it a versatile fit for new construction and retrofit projects alike. With multi-voltage support from 120 V to 347 V, it's well-suited for Canadian electrical systems across a wide range of commercial applications.
