Lithonia Lighting CM-9 PIR Low Voltage Occupancy Sensor Switch, White

The Lithonia Lighting CM-9 is a PIR (Passive Infrared) low voltage occupancy sensor switch designed to automatically control connected lighting based on real-time room occupancy. Engineered for 12-24-Volt AC/DC low voltage systems, this White sensor switch detects motion within a 10-20-ft range and signals connected lighting circuits to turn on or off without manual operation. Because the CM-9 relies on passive infrared sensing rather than manual switching, it helps eliminate lights left running in empty rooms, supporting more efficient use of connected lighting loads. Its low voltage 12-24-Volt AC/DC input makes it a straightforward fit for lighting control wiring already common in commercial and residential low voltage systems.

Key Features

  • Detection Range: Covers 10-20-ft for reliable passive infrared occupancy sensing in typical room environments.
  • Low Voltage Operation: Operates on 12-24-Volt AC/DC power, compatible with low-voltage lighting control wiring and transformer-fed systems.
  • PIR Sensing Technology: Passive infrared detection triggers automatic lighting response to occupant motion, helping eliminate lights left on in unoccupied spaces.
  • Automatic Lighting Control: Combines PIR detection with low voltage switching to turn connected lights on and off without manual intervention, supporting more efficient lighting operation.
  • White Finish: Clean White housing blends with most ceiling and wall finishes for an unobtrusive installation.
  • Model CM-9: Purpose-built low voltage sensor switch engineered specifically for occupancy-based lighting control applications.

Lithonia Lighting CM-9 – Frequently Asked Questions

1) Can the Lithonia CM-9 occupancy sensor be wired directly to a 120V lighting circuit?
No. The CM-9 is a low voltage sensor that runs on 12-24V AC/DC, so it has to be fed from a low voltage lighting control system or a transformer. It signals the connected lighting circuit rather than switching line voltage itself. If your room has a standard 120V switch leg and nothing else, you need a line voltage wall switch sensor, not the CM-9.
2) How big a room will the CM-9 PIR sensor actually cover?
Coverage is a 10-20 ft detection range, which suits normal-size rooms: private offices, small conference rooms, restrooms, break rooms, storage rooms, corridors and common areas. For a large open warehouse bay or a high-bay space you would need multiple sensors or a longer-range unit, since one CM-9 will not see across it.
3) Will a PIR occupancy sensor like the CM-9 hold lights on for someone sitting still at a desk?
Passive infrared detects motion and body heat moving through its field of view, so it needs line of sight and some movement. That makes the CM-9 a good fit for restrooms, corridors, break rooms and storage areas where people move through. In a private office where someone works at a keyboard for long stretches, or anywhere the sensor's view is blocked by partitions or stacked shelving, mount it so the occupant's normal movement falls inside the 10-20 ft range.
4) What exact part number do I order for the Lithonia low voltage PIR occupancy sensor in white?
Order Lithonia Lighting CM-9. That single model number covers it: PIR occupancy sensor switch, 12-24V AC/DC, white housing. There are no separate finish or voltage suffixes to specify.
5) Can I add the CM-9 sensor to an existing low voltage lighting control system, or is it new construction only?
Both. Because the CM-9 operates on 12-24V AC/DC control wiring that is already common in commercial and residential low voltage systems, it drops into retrofit projects as well as new construction without reworking the line voltage side.
6) Will the CM-9 work on a 12V DC system, or does it need AC?
Either. The input is rated 12-24V AC/DC, so it runs on a 12V or 24V DC supply as well as 12V or 24V AC from a control transformer.
7) Is the CM-9 only offered in white, or can I get it to match ivory or black devices?
White only. The CM-9 ships with a white housing, which blends with most ceiling and wall finishes. If your building is standardized on ivory or black trim, this sensor will not match it.
