Lithonia Lighting CMRB-6 PIR Occupancy Sensor with 15 - 20-ft Range, 120/277-Volt AC, White

The Lithonia Lighting CMRB-6 is a passive infrared (PIR) occupancy sensor switch engineered to automatically control connected lighting loads based on detected room occupancy. Designed to install in place of a standard wall switch, the CMRB-6 offers a 15 - 20-ft PIR detection range suitable for typical rooms, offices, and hallways. It operates on 120/277-Volt AC power, giving installers flexibility across common commercial and residential voltage systems. Finished in White, the CMRB-6 Sensor Switch blends into standard wall plates and lighting layouts while providing automatic, energy-conscious lighting control for professional installations.

Key Features

  • Detection Range: 15 - 20-ft PIR detection range for accurate room-level occupancy sensing.
  • Dual Voltage Operation: 120/277-Volt AC rating allows installation on a variety of standard commercial and residential lighting circuits.
  • PIR Sensing Technology: Passive infrared detection automatically switches connected lighting on and off based on occupancy within range.
  • White Finish: Clean White housing coordinates with most wall plates and lighting layouts.
  • Sensor Switch Design: CMRB-6 model configured as a self-contained occupancy sensor switch for direct installation in place of a standard wall switch.
  • Automatic Lighting Control: Senses motion within its detection range and switches connected fixtures on and off, reducing energy waste from lights left on in unoccupied spaces.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Commercial Office Spaces
  • Restrooms and Break Rooms
  • Corridors, Hallways, and Stairwells
  • Storage and Utility Rooms
  • Energy-Code Automatic Shut-Off Requirements
  • Residential and Light Commercial Lighting Circuits

Why Lithonia Lighting?

Lithonia Lighting designs occupancy sensing controls like the CMRB-6 to provide dependable, automatic lighting operation across the 120/277-Volt AC range found in most commercial and residential circuits. The PIR-based 15 - 20-ft detection range, paired with a compact White wall-switch housing, makes the CMRB-6 an easy drop-in upgrade for standard switch locations. For contractors and facility managers looking to add energy-saving occupancy control without complex rewiring, the Lithonia Lighting CMRB-6 Sensor Switch delivers a straightforward, practical solution for everyday lighting control needs.

Lithonia Lighting CMRB-6 – Frequently Asked Questions

1) Will the Lithonia CMRB-6 occupancy sensor work on a 277V commercial lighting circuit?
Yes. The CMRB-6 is rated 120/277V AC, so it goes on either a standard 120V residential/light commercial circuit or a 277V commercial lighting branch without a different part number. That dual rating is why it standardizes well across a mixed-voltage facility where some areas are 120 and others are 277.
2) Can the CMRB-6 sensor replace an existing wall toggle switch, or does it need a separate control box?
It replaces the switch. The CMRB-6 is a self-contained PIR sensor switch built to install in place of a standard wall switch in the existing single-gang box, controlling the connected lighting load directly. No separate relay pack or control module is part of this design.
3) How big a room will the Lithonia CMRB-6 PIR sensor actually cover?
The detection range is 15 to 20 feet, which is room-level coverage: private offices, restrooms, break rooms, storage and utility rooms, and short corridor or stairwell runs. A large open-plan floor or a long hallway needs more than one sensing point, because passive infrared only sees motion within that range and within its line of sight.
4) Is PIR the right sensing technology for a restroom with stalls and partitions?
Understand the limitation before you spec it. The CMRB-6 uses passive infrared, which detects heat-in-motion within its 15 to 20 foot range and needs a clear view of the occupant. In a restroom with full-height stalls or an L-shaped layout, PIR can lose a seated occupant behind a partition. For those spaces, ultrasonic or dual-technology sensing, or multiple sensing points, is the better call. Open restrooms, offices, break rooms and utility rooms are where a wall-box PIR switch does its job.
5) Can I use the CMRB-6 to meet an automatic shut-off requirement for lighting?
Automatic shut-off of lighting in unoccupied spaces is one of the stated applications for the CMRB-6, which turns connected fixtures on and off based on detected occupancy. What it does not do is certify your project: the specific energy-code article your jurisdiction enforces, and any required documentation, is a decision for the electrical engineer of record.
6) Will the white CMRB-6 sensor match the switch plates already on my other openings?
The housing is white, and it is sized to sit behind standard wall plates, so it coordinates with the white decorator plates and devices typically already in place across an office or multi-family building. For a property manager standardizing a floor, white is the only color offered under the CMRB-6 model.
7) What exact Lithonia part number should I put on the purchase order for this sensor?
Order it as Lithonia Lighting CMRB-6. That is the full manufacturer part number for the 120/277V white PIR sensor switch, and it is sold as a single configuration, so there are no finish or voltage suffixes to add.
