Switches and Lighting Controls, Occupancy Sensors, Adaptive TechnologyUltrasonic Ceiling Sensor, 2000 Square Feet Coverage, With Relay

Ultrasonic (US) technology senses occupancy by bouncing sound waves (32 kHz - 45 kHz) off of objects and detecting a frequency shift between the emitted and reflected sound waves. Movement by a person or object within a space causes a shift in frequency, which the sensor interprets as occupancy. While US occupancy sensors have a limited range, they are excellent at detecting even minor motion such as typing and filing, and they do not require an unobstructed line-of sight. This makes US technology sensors ideal for an application like an office with cubicles or a restroom with stalls.

  • Coverage 2000 sq. ft. (360°) with photocell and isolated relay, low voltage sensor
  • Minor motion detection
  • Digital, crystal controlled ultrasonic transmitter and receiver for coverage in each direction for superior sensing of movement
  • Office White ABS enclosure blends with ceiling tile
  • Relay to interface with auxiliary systems such as HVAC
  • Green LED indicates ultrasonic detection
  • "Install and Forget" operation. Auto-adjusting adaptive technology eliminates manual adjustments
