1901A SERIES MOTION SENSOR

SAVES ENERGY AND MEETS FEDERAL ENERGY REGULATIONS

  • Specifically engineered for installation in walk-in coolers and freezers
  • Uses electronic components to allow for reliable operation in extreme temperatures
  • Features a gasketed water-tight enclosure which prevents moisture and dust from entering the sensor and affecting occupancy detection
  • Operation: Passive infrared sensor detects motion and turns lights on at temperatures below freezing. Uses DIP switches to set time delay and PIR sensitivity
  • Low Bay Sensor: High density optic lens set covers a 20 ft (7.3 m) diameter with ceiling height up to 20 ft. (6.1 m)
  • High Bay Sensor: Same as the low bay sensor except with ceiling height from 20 ft. (6.1 m) to 40 ft. (12.2 m)
