TWINSENSE Dual Technology Presence Detector


UT-962i 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 and 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 the 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. 
  • The swivel mounting base design enables both ceiling and wall installations for user’s flexible application. 
  • The IR remote control is available for quick and convenient setting (Note: IR remote control is for optional purchase).
  • Applications: corridor, hotel lobby, classroom, large conference room, storage room, staircase, etc.
