Leviton High-Bay Fixture Mount Motion Sensor, Height & Aisle Lenses, PIR Tech, 120-347V

Basic Operation: The OSFHU Passive Infrared (PIR) Fixture Mount High-Bay Occupancy Sensor is specifically designed for high mounted areas such as warehouses, manufacturing and other high ceiling applications. The OSFHU installs directly to an industrial fluorescent luminaire or an electrical junction box. It is a self-contained sensor and relay that turns individual light fixtures ON or OFF based on occupancy in the detection zone. It comes with two interchangeable lenses for use in either a 360 high-bay or 360 low-bay general area or a mask for aisle way. The OSFHU provides reliable coverage up to 40 ft. mounting heights. The OSFHU is also available in a model for cold storage applications with temperatures as low as -40 F (-40 C). Installation: The OSFHU mounts directly to an industrial fluorescent fixture or an electrical junction box through a standard 1/2" knockout using the two provided lock-nuts. Wiring is connected inside the fixture body. Quicksnap: Built into the 1/2" nipple, this locking mechanism allows for the fastest and easiest mounting not requiring a threaded lock-nut. Fast, easy time delay setting: Can be set at any time without requiring power to the sensor; time delay is variable from 30s-20m. instant ON" closing relay fires lamps in under 5 seconds. Listings: UL and CUL Listed (OSFHU models), 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 Auto Temperature Calibration: Automatically adjusts the PIR sensitivity as ambient temperature rises to increase detection of heat movement through the field-of-view.
