Leviton OSFHS-ITW - PIR Surface/Recess Mount High Bay Occupancy Sensor - Interchangeable lenses - High Bay - 120/230/277/347VAC - White

Leviton OSFHS-ITW

Brand Features

The High Bay Occupancy Sensor is designed simply to automatically turn lights ON or OFF. The sensor utilizes Passive Infrared Technology (PIR) combined with Fresnel lenses to determine when an area is occupied. This is determined when a heat source is detected and moves from one facet in the lens to another. The sensor recognizes this as a motion and provides power to the light fixture. Simultaneously a timer is started and restarts with each motion, once expired, the lights will turn OFF. The high bay sensor maximizes energy savings, incorporating false detection algorithms to eliminate false ONs by nuisance tripping or background environmental conditions. The sensor also optimizes energy savings and safety concerns during power loss scenarios by assuming a return to last known state of operation

Features and Benefits

Multiple mounting options:

Quicksnap: built into a 1/2” nipple, this locking mechanism allows for the fastest and easiest installation

Keyhole: added flexibility for surface mount applications

Recess: mounts directly into a luminaire using slotted side clip design

Reduce time and materials: easily reach the ballast at either end of the fixture without requiring more wire or connectors with the included 42” wire leads

Fast, easy time delay setting: can be set at any time without requiring power to the sensor; time delay is variable from 30s-30m

Instantly verify fixture operation and wiring

connections: “instant ON” closing relay fires lamps in under 5 seconds

High Inrush Stability (H.I.S. Technology): Zero crossing circuitry optimizes relay operation for reliable, long-life operation

Robust mechanical latching relay is durable for all load types

Auto temperature calibration: automatically adjusts the PIR sensitivity as ambient temperature rises to increase detection of heat movement through the field-of-view

Return to last state: for safety and energy savings, the OSFHS 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

False detection intelligence: for increased energy savings and to mitigate nuisance tripping, the super bright LED indicates advanced detection has been activated and the lights will only turn ON when true occupancy has been determined
