Encelium - Low Voltage Ceiling-Mounted Occupancy Sensors


Low Voltage Occupancy and Daylight Sensor

The Encelium Low Voltage Sensor Family is a single-technology Passive Infra-Red (PIR) sensors that are a cost-effective option for small and large spaces when major motion is available.

The multi-technology option adds an active Ultrasonic (U/S) sensor to the PIR sensor to increase minor motion sensitivity in critical applications like single-occupant offices and restrooms between 450 to 2,000 sq. ft.

Designed with easy ceiling mounting with low-voltage connection and a twist-lock attachment for 360° directional flexibility. Includes installer test mode with 6 seconds auto exit programming.


  • Adaptive Learning with Local Protected Memory - Sensor self-calibrates to optimize performance and retains settings during power interruptions
  • Avoid wasting energy when there is enough natural light with the integrated Daylight Hold-OFF Light Sensor
  • Auto-Adapting Mode - Sensor’s digital system continually analyzes and adjusts the sensitivity and time delay
  • Walk-Through Mode - Provides increased energy savings by decreasing the time delay to 2.5 minutes when someone momentarily walks through the monitored space
