Dual Technology Presence Detector


UT-963 wall switch integrates passive infrared (PIR) sensor and ultrasonic sensor (US) technologies in it and takes advantage
of the best features of both sensors which PIR sensor is less affected by noise signal as well as airflow.
Ultrasonic sensor is of high sensitivity to ably detect small movement. The ultrasonic sensor doesn’t require an unobstructed
line-of-sight view between sensor and occupant, and dual technology detector can provide reliable performance to
minimize risk of false trigger.

  • Both PIR and ultrasonic sensors are integrated in the detector to minimize the risk of false trigger effectively and can strengthen the detection reliability.
  • High performance relay is built-in for controlling all kinds of lamps.
  • Versatile triggering methods, either only one technology (PIR or US) or both technologies (PIR and US) can be chosen for user’s flexible utilization. 
  • Considerate air current compensation function is provided to reduce the false triggering due to interruption of air flow.
  • Three operation modes ON / AUTO / OFF are available for user’s free and convenient application.
  • Fully compatible with the switch frame in dimensions of 56mm x 56mm.
