Lithonia Lighting CMR-9 PIR Occupancy Sensor with Relay, White

The Lithonia Lighting CMR-9 is a passive infrared (PIR) occupancy sensor with an integrated relay, designed to automatically control lighting loads based on detected motion within a room. Built for 120/277-Volt AC electrical systems, this white sensor covers a detection range of 10 - 20-ft, making it well suited for offices, restrooms, hallways, and other commercial spaces where automatic on/off lighting control improves energy efficiency. The built-in relay allows the CMR-9 to directly switch connected lighting loads without requiring a separate control panel, simplifying installation for electricians and facility managers alike. Its compact white housing blends into ceiling or wall installations while delivering dependable occupancy-based control.

Key Features

  • Detection Range: Senses occupant motion across a 10 - 20-ft range for reliable coverage of typical room sizes.
  • Electrical Rating: Rated for 120/277-Volt AC systems, supporting compatibility with a wide range of commercial electrical service configurations.
  • Integrated Relay: Built-in relay switches connected lighting loads directly, reducing the need for additional control hardware.
  • PIR Sensing Technology: Passive infrared detection automatically identifies occupant movement to trigger lighting control.
  • White Finish: Clean white housing designed to blend discreetly into ceiling and wall-mounted installations.
  • Model CMR-9: Part of the Lithonia Lighting sensor switch lineup for automated lighting control applications.

Lithonia Lighting CMR-9 – Frequently Asked Questions

1) Will the Lithonia CMR-9 occupancy sensor work on a 277-volt circuit, or is it 120V only?
Both. The CMR-9 is rated for 120/277-volt AC, so the same part number works on a 120V branch circuit in a small office and on a 277V circuit in a commercial lighting panel. That matters if you are standardizing one sensor across a building where some areas run 277V fluorescent or LED lighting and others run 120V.
2) Does the CMR-9 sensor need a separate lighting control panel or power pack to switch the lights?
No. The CMR-9 has an integrated relay that switches the connected lighting load directly, so you are not adding a remote power pack or a control panel to make it work. For an electrician that keeps the rough-in simple: sensor, line, and load.
3) How big a room will the Lithonia CMR-9 PIR sensor cover?
The CMR-9 detects occupant motion over a 10 to 20 foot range, which puts it in private offices, restrooms, break rooms, and corridor segments rather than large open-plan areas. For a big warehouse floor or an open bullpen you would be looking at multiple sensors or a longer-range coverage pattern instead of one CMR-9.
4) Is a PIR occupancy sensor like the CMR-9 the right choice for a restroom with stalls?
PIR sensing is line-of-sight: passive infrared picks up heat movement it can actually see, so partitions, stall walls, and tall storage block detection. The CMR-9 works well in open restrooms, hallways, and single offices where the sensor sees the whole space. In a multi-stall restroom or an L-shaped room, plan on more than one sensor or a technology that is not purely line-of-sight.
5) What exact part number do I order for the Lithonia CMR-9 occupancy sensor?
Order Lithonia Lighting CMR-9. It is a single catalog number with no voltage, color, or range suffix to specify, since one unit covers both 120V and 277V and is only offered in white.
6) Can the CMR-9 be used for an energy code retrofit in an existing office?
That is one of its intended uses. Because the relay is built into the sensor, the CMR-9 can be added to existing lighting circuits for automatic on/off control without new control wiring back to a panel, which is what makes it practical on occupancy-control retrofits in offices, corridors, and break rooms as well as new construction.
7) What color is the Lithonia CMR-9 and will it match white devices already in the building?
White. The CMR-9 housing is white, which is the standard device color in most commercial offices, so it blends with existing white wall plates and ceiling finishes on a retrofit. There is no other color offered under this model, so if your facility is standardized on ivory or black devices the sensor will not match.
