Additional Features


The CMR-PDT Series occupancy sensors combine the industry's leading Passive Infrared (PIR) technology with Microphonics™ for awesome detection in areas with or without obstructions. These attractive ceiling mount sensors are perfect for large restrooms and are an ideal solution for retrofitting classrooms with concrete ceilings. Simply install one CMR-PDT per switch and you’re covered. Additionally, the CMR-PDT Series is line powered, therefore it requires no external Power Packs which can be difficult to hide.



Sensor Operations


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.

Installation Notes

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.
