Lithonia Lighting CMR-PDT-9 Dual Technology PIR/Microphonics Occupancy Sensor with Relay, White

The Lithonia Lighting CMR-PDT-9 is a dual technology occupancy sensor with relay, combining passive infrared (PIR) and microphonics (ultrasonic) detection methods to deliver dependable, code-driven lighting control for commercial spaces. Engineered for a 10 - 20-ft detection range, this sensor operates on 120/277-Volt AC and is finished in White to complement standard commercial ceiling and wall applications. The built-in relay allows the sensor to directly switch connected lighting loads, simplifying installation in offices, classrooms, hallways, and other occupied spaces. Pairing two detection technologies in a single White housing helps reduce false triggers and nuisance shut-offs common to single-technology sensors.

Key Features

  • Dual Technology Detection: Combines PIR (passive infrared) and microphonics (ultrasonic) sensing for accurate, reliable occupancy detection that helps reduce false triggers and missed detections.
  • Integrated Relay: Built-in relay lets the CMR-PDT-9 directly switch connected lighting circuits, streamlining installation and control wiring.
  • Detection Range: Rated for a 10 - 20-ft coverage area, suited to a range of room sizes and commercial layouts.
  • Dual Voltage Operation: Operates on 120/277-Volt AC, providing flexibility for installation across standard commercial electrical systems.
  • White Finish: Clean White housing blends easily with standard ceiling and wall finishes in commercial interiors.
  • Energy-Saving Control: Automatically switches connected lighting based on real-time occupancy, helping reduce unnecessary energy use in unoccupied spaces.
  • Sensor Switch Design: Configured as a self-contained occupancy sensor switch for straightforward retrofit or new-construction lighting control.

Lithonia Lighting CMR-PDT-9 – Frequently Asked Questions

1) Will the Lithonia CMR-PDT-9 occupancy sensor work on a 277V commercial lighting circuit?
Yes. The CMR-PDT-9 is a dual-voltage device rated 120/277V AC, so it drops onto either a 120V branch circuit in a tenant office or a 277V circuit common in commercial and institutional buildings. One part number covers both, which is useful if you are standardizing controls across a facility with mixed voltages.
2) Does the CMR-PDT-9 need a separate relay or power pack to switch the lights?
No separate power pack is needed for the load it controls. The CMR-PDT-9 has an integrated relay, so the sensor switches the connected lighting circuit directly. That keeps the control wiring to the sensor itself rather than running low-voltage back to a remote pack.
3) What size room does the CMR-PDT-9 occupancy sensor cover?
Coverage is rated at a 10 to 20 ft detection range. That suits private offices, classrooms, conference rooms, restrooms, break rooms, and corridor segments. For a large open-plan floor or a warehouse aisle you will need multiple sensors or a longer-range coverage product instead.
4) Why pick a dual technology PIR sensor over a plain passive infrared occupancy sensor?
A PIR-only sensor needs line of sight motion, so it can shut lights off on someone sitting still at a desk or behind a restroom partition. The CMR-PDT-9 pairs PIR with microphonics (ultrasonic) detection, so sound and minor activity hold the lights on after gross motion stops. That combination cuts both nuisance shut-offs and false triggers, which is why it is the usual choice for offices, classrooms, and restrooms rather than a single-technology unit.
5) Can the CMR-PDT-9 be used as a retrofit replacement for an existing wall switch?
It is built as a self-contained occupancy sensor switch, so it is intended for both retrofit and new construction lighting control. The relay is on board and it handles 120 or 277V, so replacing a manual toggle switch in an existing box is a direct line-voltage swap on the switch leg.
6) What color is the Lithonia CMR-PDT-9 sensor, and is another finish offered?
White only. The CMR-PDT-9 is supplied in a white housing to match standard commercial ceiling and wall-plate finishes. If your building is standardized on ivory or a dark finish, this part will not match.
7) Is CMR-PDT-9 the exact Lithonia part number to order?
Yes, CMR-PDT-9 is the manufacturer part number, and it is the dual technology PIR/microphonics configuration with relay in white. The PDT in the designation is the dual-tech sensing version, so if a drawing calls for a PIR-only Lithonia sensor it is a different catalog number.
