Intermatic IOS-DDR-WH Commercial Grade Dual Load In-Wall PIR Occupancy/Vacancy Sensor, No Neutral Required, White

The passive infrared sensors work by detecting the difference between heat emitted from the human body in motion and the background space. The sensor switch can turn a load ON and hold it as long as the sensor detects occupancy. After no motion is detected for the set time delay, the load turns OFF automatically. The IOS-DDR has two relays (equal to Dual Load Switch).


  • Passive Infrared (PIR) sensing for presence detection
  • Coverage: 180º, 1200 ft2 with non-obstructed views
  • Independent load control for each circuit
  • Zero-crossing technology for long life and performance
  • Incandescent/Fluorescent/CFL/LED compatible
  • IOS-DDR-WH does NOT require a neutral
  • Fits standard decorator wall plate (included)
  • Time delay OFF ranging from 15 seconds to 30 minutes
  • Two ON/OFF push buttons allow control of two loads independently
  • Multiple configurations (e.g. auto ON-manual ON, auto ON-auto ON) for primary and secondary loads


  • Indoor Sensing Control
