Leviton HB011-PDX High-Bay Fixture Mount Motion Sensor w/Daylight Harvesting PIR Tech 120-277V HB011-PDX 

Basic operation whether factory or field installed new installation or retrofit leviton fixture mounted sensors provide fast easy installation and immediate energy savings by automatically activating lighting only during periods of occupancy. Reliable passive infrared (pir) technology detects occupancy and the variable time delay-up to 30 minutes-is user accessible without power tools or disassembly and allows the ideal setting based on application needs. Included with the sensor are lenses for high-bay and low-bay allowing one unit to cover a variety of applications. The innovative autocal feature performs an automatic daylight level calibration. Once calibrated the sensor requires no further adjustment and immediately enters daylighting mode actively switching the connected fixture load on and off in response to occupancy and available natural light maximizing energy savings through efficient light harvesting. Installation the hb011 installs directly to an industrial fluorescent fixture or an electrical junction box through a standard 1/2" knockout using the provided lock-nut. Wiring is connected inside the fixture body. Rotating light sensor optimal for best performance in locating light measurements (up down and side lighting). Auto calibration set to auto-calibration light sensor measures lowest light level of facility with all lights on for 24 hours to determine the daylighting set point performance daylighting enhanced design algorithms to assure lights will not cycle during cloud cover or varying light levels. (no more daylight load will turn off in +/- 5 minutes daylight returns load will turn on +/- 1 minute). Listings ul 916 csa 22.2 no. 205 m1983 fcc certified can be used to comply with 2016 title 24 part 6 occupancy sensing requirements return to last state for safety and energy savings the osfhu contains a latching relay so that in the event power is lost to the device the device will return to the last known state of the relay
