Standard Range 360° Sensor - Ceiling Mount, Line Voltage, Dual Technology (PDT)


The CMR PDT 9 Series occupancy sensors combine the industry's leading Passive Infrared (PIR) technology with Microphonics for awesome detection in areas with or without obstructions. With an integrated line switching relay, the CMR PDT 9 is perfect for applications where locating a power pack is difficult. These attractive sensors are perfect for classrooms, private offices, or large restrooms.

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. This state-of-the-art design requires no field calibration or sensitivity adjustments.
