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.
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.

hallway, ensuring the sensor can view the entire room from this position.
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.
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.
locating sensor near HVAC air diffusers because the "noise" generated from air
flow will decrease the sensitivity of the Microphonics™ sensor.
