Passive Infrared Fixture Mount High Bay Occupancy Sensor, Fixture Mounted, Cold Storage, Alternating Dual Relays, Selectable Time Delays: 1st relay 30s-30m, 2nd relay 30s-infinity. Interchangeable Adjustable 360° Lenses, Blue Low Bay

• 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

• Manual calibration: optimize energy savings and operation by manually configuring 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).

• Fast and simple setting: the OSFHD do not require power to set the time delay saving valuable time during installation - Load 1 = 30s-30m  - Load 2 = 30s-infinity (starts after load 1 expires)

• Fast and simple testing: OSFHD will “instant ON” within 5 seconds. Upon initial power, relay is closed enabling labor savings testing in seconds.

• Power interruption state: for energy savings and safety, if power is lost to device, device will return to last known state

• Fast, simple installation: sensors easily installs on individual fixtures using standard 1/2” knockouts and the quicksnap feature which eliminates the time to tighten the lock-nut. The 42” wire leads reduce time and materials for connecting the ballast. Simply make the electrical connections inside the ballast compartment, install the appropriate adjustable lens assembly included, and the sensor is ready. Ideal for use in warehouses, manufacturing, cold storage and other high ceilings.

• Zero crossing circuitry: relay uses a zero crossing circuitry to provide reliable, long-life operation

• Range and coverage: the 360° high-bay PIR lens provides a 2:1 spacing to mounting height coverage under 25 ft. mounting and a 1.5:1 for heights up to 40 ft. mounting. The 360° low-bay lens provides 2:1 spacing to mounting height coverage for 8 ft. to 20 ft. mounting.

• LED: super bright green LED indicates occupancy detection and can be seen at 40 feet

• False detection protection: Energy saving technology is designed into the OSFHD to assure your lights are on only when needed
