DESCRIPTION
Leviton's High Bay Occupancy Sensors, Cat. No. OSFHU-ITW and OSFHU-CTW (cold storage), are specifically designed for high mounted areas such as warehouses, manufacturing and
other high ceiling applications. The OSFHB-xTW installs directly to an industrial luminaire or an electrical junction box. It is a self-contained sensor and relay that detects motion using the
passive infrared (PIR) to sense sources (such as a person entering a room) within its field-of-view (monitored space) and automatically switches lights ON. The controlled lights will remain ON
until no motion is detected and the scheduled time-delay has expired. The OSFHU-xTW is supplied with two, interchangeable lens rings that allows the user to select between a 360 degree
pattern or an aisle pattern.
Cat. No. OSFHB-ITW is UL listed, cUL listed and conforms to California Title 24 requirements. The Sensor's PIR lens is designed for 20 ft. to 40 ft. mounting heights for either symetrical
pattern or an aisle pattern which will provide coverage of 50' to 60' diameter (refer to Figures 4 and 5). The Sensor is sensitive to the heat emitted by the human body. In order to initially
trigger the Sensor, the source of heat must move from one zone of detection to another.
Note that occupancy sensors respond to rapid changes in temperature, so care should be taken not to mount the device near a climate control source (i.e. radiators, air exchanges, and air
conditioners). Hot or cold drafts will look like body motion to the device and will trigger it if the unit is mounted too close. It is recommended to mount the Occupancy Sensor at least 6 ft.
away from the heating or cooling ventilation source.
INSTALLATION INSTRUCTIONS
WARNING: TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE ELECTRICAL CODES AND REGULATIONS.
WARNING: IF YOU ARE NOT SURE ABOUT ANY PART OF THESE INSTRUCTIONS, CONSULT A QUALIFIED ELECTRICIAN.
WARNING: CONTROLLING A LOAD IN EXCESS OF THE SPECIFIED RATINGS WILL DAMAGE THE UNIT AND POSE RISK OF FIRE, ELECTRIC SHOCK, PERSONAL INJURY OR
DEATH. CHECK YOUR LOAD RATINGS TO DETERMINE THE UNIT’S SUITABILITY FOR YOUR APPLICATION.
OTHER CAUTIONS AND NOTES:
1. DISCONNECT POWER WHEN SERVICING LUMINAIRE OR CHANGING BULBS.
2. USE THIS DEVICE WITH COPPER OR COPPER CLAD WIRE ONLY. WITH ALUMINUM WIRE USE DEVICES MARKED CO/ALR OR CU/AL ONLY.
3. DO NOT ATTEMPT TO DISASSEMBLE OR REPAIR. CLEAN OUTER SURFACE WITH A DAMP CLOTH ONLY.
TO INSTALL:
NOTE: The OSFHU-xTW is supplied with two lens trim rings. The 360 degree lens (white color trim ring) is installed at the factory with the aisle lens (black color trim ring) in the carton. Change
the lens for use in aisle applications. See below for changing lens trim ring. The OSFHU-xTW Sensor mounts in a 1/2" knock out hole on the end of a luminaire or an electrical box. The
Sensor’s field-of-view may be partially obstructed by the luminaire housing (refer to Figure 1A). At higher mounting heights, the outer beams are not used. As long as the bottom of the sensor
is mounted within 1" from the bottom of the luminaire, the field-of-view will not be affected (refer to Figure 1B).
ADAPTER NOTE: For deep bodied luminaires or to clear other obstructions use Leviton's OSFOA-00W Adapter (refer to Figure 2A). The Adapter is designed to provide multiple mounting
positions to accommodate different mounting heights for optimum sensor positioning (refer to Figure 2B). Provided is a keyed, threaded snap-in nipple that holds the Adapter in place while
tightening the provided lock-nut. If the Adapter is needed, go to ADAPTER INSTALLATION section.
SENSOR INSTALLATION:
1. WARNING: TO AVOID FIRE, SHOCK, OR DEATH: TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND TEST THAT THE POWER IS OFF BEFORE WIRING.
2. The sensor comes with two lens rings, a white one for 360 degree detection (installed at factory) and a black one for aisle applications. NOTE: An optional peel and stick masking kit is
included. This circular adhesive label (with removable wedges) is applied to the OUTSIDE of the sensor lens. Use any number of wedges to alter field-of-view for your desired application.
3. To change lens, turn trim ring so that the two indented dots line up and and pull out by the finger tabs (refer to Figure 6A).
4. To insert the black aisle lens, line up the indented dots and indented tabs on underside of lens and insert into key openings and turn clockwise (refer to Figure 6B).
5. Line the finger tabs with the direction of the aisle. The lens will snap into indentation bumps to indicate the lens direction is at either 90 degree or 0 degree orientation.
6. Remove the lock-nut from the threaded nipple and insert the wires and the threaded nipple into a half inch hole of the luminaire body or the electrical box.
7. Slide the lock-nut over the wires and thread clockwise on to the threaded nipple to secure the sensor firmly in place making sure the lens is orientated towards the area to be monitored
(field-of-view) (refer to Figure 3).
8. Connect wires per Wiring Diagram as follows: BLACK lead to LINE (Hot); RED lead to LOAD; WHITE lead to LINE (Neutral). Twist strands of each lead tightly and, with circuit conductors,
push firmly into the appropriate wire connector. Screw connector on clockwise making sure that no bare wire shows below the connector.
9. Restore power at circuit breaker or fuse.
NOTE: Allow approximately 1 minute for charge-up. If the lights turn ON and the LED blinks when a hand is waved in front of the lens, then the Sensor was installed properly. If the operation is
different, refer to the Troubleshooting Section.
The Sensor is factory preset to work without any adjustments. If you desire to change the factory settings, refer to the SETTINGS section.
ADAPTER INSTALLATION:
1. Position one half of the Adapter body on the end of the luminaire to determine the appropriate mounting hole to be used on the Adapter that will position the sensor for optimum coverage.
The bottom of the sensor should be at or below the luminaire body (refer to Figure 2B).
2. Punch out the keyed hole of the Adapter half body to be mounted on the luminaire or electrical box (refer to Figure 1B).
3. Thread the provided lock nut part way on the keyed threaded nipple and insert through the keyed hole from the inside of the Adapter half body and snap into the half inch hole of the
luminaire or electrical box and tighten (refer to Figure 2A).
4. Punch out the non-keyed hole on the other Adapter body half and insert the wires and threaded nipple of the Sensor into the hole. Thread the provided lock nut on the nipple and tighten
positioning sensor towards the area to be monitored (refer to Figure 2A).
5. Feed the sensor wires through the keyed nipple attached to the luminaire or electrical box and connect per Wiring Diagram as follows: BLACK lead to LINE (Hot); RED lead to LOAD;
WHITE lead to LINE (Neutral). Twist strands of each lead tightly and, with circuit conductors, push firmly into the appropriate wire connector. Screw connector on clockwise making
sure that no bare wire shows below the connector.

together.
NOTE: To open the Adapter, use a small, flat blade screw driver and
carefully insert into slots and push tabs down while pulling the two halves
apart.
7. Restore power at circuit breaker or fuse.
NOTE: Allow approximately 1 minute for charge-up. If the lights turn ON
and the LED blinks when a hand is waved in front of the lens, then the
Sensor was installed properly. If the operation is different, refer to the
Troubleshooting Section.

SETTINGS
Time-Delay: Settings should be determined during the installation period.
This adjustment controls the amount of time the lights stay ON after the last
detected motion. You may select settings varying from 30 seconds
to 20 minutes and any time in between.
NOTE: After power is turned ON, allow two minutes for this unit to warm up
before performing Time-Delay settings.
TROUBLESHOOTING
• Lights will not turn ON
- Circuit breaker or fuse is OFF: Turn the breaker ON. Ensure the
lights being controlled are in working order (i.e., working bulbs, ballasts,
etc.)
- Sensor is wired incorrectly or may be defective: Confirm that the
sensor’s wiring is done correctly and inspect visually for problems.
- Lens is dirty or obstructed: Inspect the lens visually and clean if
necessary, or remove the obstruction.
• Lights will not turn OFF
- Sensor is wired incorrectly or may be defective: Confirm that the
sensor’s wiring is done correctly and inspect visually for problems.
- Sensor may be mounted too closely to an air conditioning or
heating vent: Move the sensor or close the vent.
- The line voltage has dropped: Perform the necessary tests to ensure
the line voltage has not dropped beneath 100V.
• Lights turn OFF and ON too quickly
- Sensor may be mounted too closely to an air conditioning or
heating vent: Move the sensor to another location or close the vent.
- Time delay set improperly: Adjust the TIME DELAY.
