The CM family of ceiling mount occupancy sensors provide a range sensor solutions for applications with finished ceilings (e.g. Ceiling tiles, sheetrock, plaster). CM family sensors utilize 100% digital Passive Infrared (PIR) detection and are available with several lens options, providing flexibility for multiple mounting height and coverage pattern requirements, Dual technology (PDT) occupancy detection can also be added as an option for applications where occupants are stationary for long periods of time.
