360°Ceiling Mount Fixture Motion Sensor




Please Contact our Sales Department for more information

Passive Dual Technology in a Line Voltage occupancy sensor that fits in the palm of your hand! The CMRB-PDT incorporates the industry’s leading Passive Infrared (PIR) technology with Microphonics™ for awesome detection in areas with or without obstructions. Capable of being mounted to pendant or surface mounted fixtures utilizing the 1/2" knockouts, the CMRB-PDT runs on line voltage and switches loads directly without the need of a Power Pack.

Typical Applications


Exhaust KitsRestroom with Stalls

Exhaust KitsClassrooms (Multiple Sensors)

Exhaust KitsStorage Rooms with Shelving

Exhaust KitsConcrete/Drywall Ceilings

Best choice for small motion (e.g. hand movements) detection
• Viewing angle of 56º in a 360º conical shaped pattern
• Provides 12 ft radial coverage when mounted to standard 9 ft ceiling
• 8 to 15 ft mounting heights provide 10 to 20 ft radial coverage
• Microphonics™ detects normal human activity up to 20 feet, but will
detect greater distances in spaces with hard floors or very
quiet rooms with little or no background noise

Sensors with Passive Dual Technology (PDT) first “See” motion using Passive Infrared (PIR) and then engage Microphonics™ to “Hear” sounds that indicate continued occupancy. This patented technology uses Automatic Gain Control (AGC) to dynamically self adapt a sensor to its environment by filtering out constant background noise and detecting only noises typical of human activity. When occupancy is detected, a self-contained relay switches the lighting “On. The sensor is line powered and can switch line voltage (see specifications). An internal timer, factory set at 10 minutes, keeps the lights “On” during brief periods of no activity. This timer is push-button programmable from 30 seconds to 20 minutes, and is reset every time occupancy is re-detected. If needed, a 10 second grace period also allows the lights to be voice reactivated after shutting off.

Spec Sheets



Exhaust KitsPlace the sensor along the entrance door wall to prevent it from viewing out into the hallway, ensuring the sensor can view the entire room from this position.

Exhaust KitsPassive Infrared sensors detect motions crossing the beams much stronger than when entering the beams. The outer beams used for initial detection should be aligned for maximum coverage.

Exhaust KitsHeat producing sources controlled by the sensor must not be in the view pattern of the sensor. If sensor cycles or appears to continually stay "On", move sensor or mask lens segments that view the source.

Exhaust KitsAvoid locating sensor near HVAC air diffusers because the "noise" generated from air flow will decrease the sensitivity of the Microphonics™ sensor.
