Sensor Switch Cmr-Pdt-2P Passive Dual Technology Occupancy Sensor 2 Line Voltage Pdt Pir Daylight Control - White

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, two separate self-contained relays switch the loads �On�. The sensor is line powered and can switch a large range of line voltages. Each pole has an internal timer, factory set at 10 minutes, which keep the lights �On� during brief periods of no activity. These timers are each programmable at 2.5 minute increments from 30 seconds to 20 minutes, and are reset every time occupancy is re-detected. This state-of-the-art design requires no manual field adjustments. This series offers an Inhibit Photocell (-P) option of both poles separately for spaces with abundant natural light. Ideal for Automatic Bi-Level Lighting Control in public areas with windows like vestibules, corridors, or bathrooms; the -P option can inhibit the lights from turning on if there is sufficient daylight available. Once the lights are needed and turn on, however, they stay on until the occupancy sensor timer expires. In this option the set-point for each pole is independently programmable.
