Low-Voltage PIR/Photo Occupancy Sensors

Ceiling Mounted

Ceiling Mounted Occupancy Sensors

Key Features & Benefits

  • State of the Art Sensors: Passive Infra-Red (PIR) sensor and optional Ultrasonic (U/S) sensor afford a wide variety of space coverage while providing options for fine motion sensitivity. (450 to 2000 sq. ft., see Ordering Information table.)
  • Simple Installation: Easy ceiling mount with low-voltage connection and twist-lock attachment for 360° directional flexibility.
  • Flexible Timer Settings:
    Automatic – 30 seconds – 30 minutes. 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.
  • Low Voltage Operation: Uses ENCELIUM EXTEND PPK Series Power Pack with Class 2, 24 volt wiring. Multiple sensors can control single or multiple power packs.
  • Convenient AC Power Base Option: Make any ENCELIUM EXTEND low-voltage ceiling sensor a line-voltage sensor and avoid bulky external power-packs. (see PBA-015)
  • Integrated Daylight Hold-OFF Light Sensor: Avoid wasting energy when there is enough natural light.
  • 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.

Modern occupancy sensors use digital technology to ensure that the occupants in a room have light when they are present and that lighting energy is saved when the room is unoccupied.

Depending on the application, either single technology or multi-technology sensors are appropriate to maximize occupant and energy manager satisfaction.

ENCELIUM EXTEND single-technology Passive Infra-Red (PIR) sensors 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.
