Lithonia Lighting CM-PDT-9 Dual Technology Low Voltage Occupancy Sensor Switch

The Lithonia Lighting CM-PDT-9 Dual Technology Low Voltage Occupancy Sensor Switch combines Passive Infrared (PIR) and Microphonics sensing technologies to deliver dependable, energy-saving lighting control for commercial and institutional spaces. Engineered for a 10 - 20-ft detection range, this White sensor switch operates on 12 - 24-Volt AC/DC low-voltage power, making it a versatile fit for automated lighting control systems that rely on low-voltage wiring. By pairing two distinct detection methods, the CM-PDT-9 helps minimize false triggers and premature shut-offs that can occur with single-technology sensors, supporting more consistent, occupancy-based lighting performance throughout the day in offices, corridors, and other commonly occupied commercial areas.

Key Features

  • Dual Technology Detection: Combines Passive Infrared (PIR) and Microphonics sensing in a single low-voltage sensor switch for accurate, reliable occupancy detection.
  • Coverage Range: Detects occupancy across a 10 - 20-ft range, supporting consistent lighting control coverage in typical rooms and open work areas.
  • Low Voltage Operation: Operates on 12 - 24-Volt AC/DC power, compatible with low-voltage lighting control systems commonly specified in commercial buildings.
  • Sensor Switch Design: Functions as an integrated occupancy sensor switch, automatically controlling connected lighting loads based on detected room occupancy.
  • Reduced False Triggers: Dual-technology sensing helps reduce nuisance activations and premature shut-offs compared to single-technology occupancy sensors.
  • Finish: White housing coordinates with most ceiling and wall finishes for a clean, unobtrusive installed appearance.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Office and Conference Room Lighting Control
  • Corridor and Hallway Occupancy Sensing
  • Restroom and Break Room Automatic Lighting
  • Commercial and Institutional Buildings
  • Energy-Efficient Lighting Retrofits
  • Low-Voltage Lighting Control Systems

Why Lithonia Lighting?

Lithonia Lighting CM-PDT-9 – Frequently Asked Questions

1) Can the Lithonia CM-PDT-9 occupancy sensor be wired directly to a 120V lighting circuit?
No. The CM-PDT-9 is a low voltage sensor, rated 12-24V AC/DC, so it has to be powered from a low voltage lighting control system (a power pack or control panel supplying that range). It does not take line voltage directly. If your job has no low voltage control gear in the ceiling, you need a line voltage wall or ceiling sensor instead.
2) What size room will the CM-PDT-9 sensor actually cover?
Detection range on the CM-PDT-9 is 10 to 20 ft, which suits private offices, conference rooms, restrooms, break rooms, and corridor segments. For a large open office or warehouse bay you would need multiple sensors spaced within that range, or a longer-range sensor.
3) Do I need anything besides the CM-PDT-9 to switch my lights?
Yes. Being a low voltage sensor, the CM-PDT-9 does not break the line voltage load itself. It reports occupancy on 12-24V AC/DC, so the circuit needs a low voltage power pack or a lighting control panel/relay to supply the sensor and switch the connected fixtures. Plan that device into the order if the ceiling does not already have one.
4) What does dual technology mean on this Lithonia sensor, and is it worth it over a plain PIR?
Dual technology here means Passive Infrared plus Microphonics in one head: it looks for body heat movement and listens for sound. The practical difference is fewer nuisance shut-offs in spaces where someone sits still (a desk, a restroom stall, a conference room with one person typing) because sound keeps the lights held on after motion stops. A PIR-only sensor in those rooms is the classic lights-go-out-on-you complaint.
5) What is the exact part number to specify for this Lithonia dual tech low voltage sensor?
Order it as Lithonia Lighting CM-PDT-9. That is the manufacturer part number, and it is a single configuration: dual technology PIR/Microphonics, White, 12-24V AC/DC.
6) Is the CM-PDT-9 suitable for an energy code retrofit in an existing office building?
It is built for exactly that kind of work: automatic occupancy-based control in offices, corridors, restrooms, and break rooms, including energy-efficient lighting retrofits. The one condition is the wiring. Because it runs on 12-24V AC/DC, the retrofit only works where low voltage control wiring and a power pack can be run to the sensor location.
7) Will the CM-PDT-9 match the other sensors and devices already in my ceilings?
The housing is White, which is the standard finish for commercial ceiling-mounted sensor heads and generally reads clean against white tile and painted drywall. If your existing devices are black or an architectural color, it will not match.
