UT-974i

Dual-Technology Presence Detector


Specification

UT-974i integrates passive infrared (PIR) sensor and ultrasonic sensor (US) technologies in it and takes advantage of the best features from both sensors which PIR sensor is immune to noise signal and airflow  whereas ultrasonic sensor’s high sensitivity allows to detect small movement and it doesn’t require an unobstructed line-of-sight view between the sensor and occupant. 
The dual technology detector can provide reliable performance to minimize the risk of  false trigger.

Features
  • 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. 
  • Versatile mounting methods of ceiling surface mount, ceiling flush mount with spring clamp as well as ceiling flush mount with European junction box are feasible.
  • Can be connected with slave detector to enlarge the detection coverage for wide space application. 
  • The IR remote control is available for quick and convenient setting (Note: IR remote control is for optional purchase).
  • Applications: partitioned open-plan office, classroom, large conference room, multi-stall restroom, etc.
