High-Performance Sensor Works in High Places to Save Energy and Time

Ideal for new installations or retrofits, whether factory or field installed, this feature-packed, fixture-mounted, high-bay sensor from Leviton and Graybar offers fast, easy installation and immediate energy savings by automatically activating lighting only during periods of occupancy.

Leviton OSFHP PIR High Bay Sensor

Looking for a fixture-mounted high bay sensor that can handle high ceilings – up to 40 ft. – in warehouses, manufacturing facilities, production floors, industrial areas and other high-ceiling applications? Leviton and Graybar have the solution: the versatile OSFHP & OSFHD PIR Fixture Mount High Bay Sensor with Integrated Light Sensor. It's specifically designed for high-ceiling applications, but also works in applications where daylighting, bi-level switching, low voltage (HVAC), 480V, safety/security lighting and cold storage are required.

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 min. – is user accessible without power, tools or disassembly; it also permits the ideal setting based on application requirements. Use the sensor for high-bay, low-bay or aisle mounting; the unit comes with lenses for each application.

These innovative sensors feature the unique Autocal function that performs automatic daylight level calibration. Once calibrated, the sensor requires no further adjustment and immediately enters daylight harvesting mode, actively switching the connected fixture load ON and OFF in response to occupancy and available natural light. The result: maximum energy savings through efficient light harvesting.

Value-added Features Include:

Rotating Light Sensor

Optimal for best performance in locating light measurements (up, down and side lighting). Use in open- and closed-loop applications.

Manual Calibration

Manually configure the daylighting set point to optimize energy savings and operation.

Auto Calibration

When 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 assure lights will not cycle during cloud cover or varying light levels.

Fast and Simple Setting

The OSFHP and OSFHD do not require power to set the time delay, saving valuable time during installation.

Fast and Simple Testing

The OSFHP and OSFHD will "Instant On" within five seconds. Upon initial power, relay is closed, resulting in labor-saving 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

The OSFHP and OSFHD sensors easily install on individual fixtures using standard 1/2 in. knockouts and the quicksnap feature. Simply make the electrical connections inside the ballast compartment, install the appropriate adjustable lens assembly included, and the sensor is ready. 42 in. wire leads reduce time and materials needed for connecting the ballast. Masking is provided for fine tuning the coverage pattern.

Zero Crossing Circuitry

Relay uses a zero crossing circuitry to provide reliable, long-life operation.
