Ceiling Mount Occupancy Sensor

The Acuity Sensor Switch CM 9 is a ceiling mounted occupancy sensor designed for indoor lighting control. It uses passive infrared technology to detect motion within a coverage area up to 452 sq ft from a maximum mounting height of 15 ft. The unit operates on 12 to 24V DC and provides 0-10V dimming output for compatible ballasts or drivers. Hard wired communication ensures a reliable connection to the lighting control system.

Suited for Commercial Lighting Retrofits

This sensor suits installers adding occupancy based control to fluorescent, incandescent or LED fixtures in offices, hallways or classrooms. The white finish and included self tapping screws support standard ceiling installation. Projects requiring wireless communication, line voltage switching without a separate control unit, or coverage beyond 452 sq ft will need a different solution. The sensor is compliant with BAA, CA Title 24 and RoHS standards for regulated projects.

0-10V Dimming Output

The defining specification is the 0-10V dimming interface which requires a compatible dimmable ballast or driver to function. Without a matching control unit the sensor cannot switch the load directly as the load rating at 120V AC is dependent on that external unit rating. Verify the lighting system accepts a 0-10V control signal before specifying this model.

Questions about this item

How large an area does the 452 sq ft coverage handle once installed?

The sensor detects occupancy across up to 452 sq ft when mounted at the recommended height, suitable for open offices, classrooms or corridors.

What does the 0-10V dimming interface actually control in practice?

The hard-wired 0-10V output adjusts compatible fluorescent, incandescent or LED drivers smoothly from minimum to full brightness.

What hardware is needed to mount the unit on a ceiling?

Two self-tapping screws are included; the sensor fits a standard ceiling opening and mounts directly to the surface.
