The CMRB-PDT-2P Series is a Dual Technology occupancy sensor that is capable of controlling 2 Line Voltage Loads. The CMRB-PDT-2P incorporates the industrys 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-2P is powered from line voltage and switches loads directly without the need of a Power Pack. Private offices, conference rooms, or storage rooms with shelving can be controlled by just one CMRB-PDT-2P.
