Leviton OSC05-RUW – Frequently Asked Questions

1) Can I wire the Leviton OSC ceiling occupancy sensor straight to a 120V lighting circuit?
No. The Leviton OSC ultrasonic ceiling sensor is a low-voltage device that runs on 24VAC/VDC, so it needs a 24V power supply or a lighting control panel to feed it. It does not switch line voltage itself; the output is a 1A 30VAC/DC isolated relay, which is meant to signal a control panel or drive a low-voltage load. If you need a sensor that switches the load directly at line voltage, this is the wrong part.
2) Which Leviton OSC model do I need for a 500 sq ft conference room versus a large open office?
Two coverage ratings are offered: the OSC05-RUW covers 500 sq ft and the OSC10-RUW covers up to 1,000 sq ft. For a 500 sq ft conference room the OSC05-RUW is sized for the space; for larger open work areas use the OSC10-RUW, or multiple sensors if the area exceeds 1,000 sq ft per unit.
3) Ultrasonic or PIR for a ceiling sensor in an office with partition cubicles?
The Leviton OSC ceiling sensor uses ultrasonic detection, which works by sound-wave reflection and therefore picks up motion in spaces with partial obstructions such as cubicle partitions. A passive infrared alternative in ceiling form is the Pass & Seymour CI305 Wattstopper low-profile ceiling PIR sensor, rated 360 degrees and 1200 sq ft; PIR requires line of sight to the occupant, so it favors open rooms and corridors over partitioned floors. If you want both technologies in one head, the Pass & Seymour DT300 Wattstopper dual technology ceiling sensor combines them at 24V, 360 degrees.
4) What is the closest ultrasonic ceiling sensor to the Leviton OSC10-RUW if I need more than 1000 sq ft of coverage?
The Leviton OSC ultrasonic ceiling sensor tops out at 1000 sq ft with the OSC10-RUW model, so for a larger open area the Pass & Seymour UT3053 Wattstopper ceiling mount ultrasonic sensor is the direct step up - it is also a 24V ceiling ultrasonic unit and is rated for 360 degree, 2000 sq ft coverage. Both use ultrasonic sensing and 24V control wiring, so the low-voltage infrastructure and power pack approach stays the same; you are changing the pattern size, not the system.
5) Does this Leviton ceiling sensor satisfy California Title 24 for automatic shutoff?
The OSC ultrasonic ceiling sensor is listed as Title 24 Compliant and NAFTA Compliant, and carries cUL/US certification. That makes it usable in energy-code-regulated jurisdictions for occupancy-based lighting control, though the overall control design still has to be laid out to meet the code sections for your space type.
6) Can I use the Leviton OSC sensor as a wall-mounted replacement switch?
No. It is built as a ceiling-mount sensor and has no line-voltage switching, so it will not drop into a wall switch box in place of a toggle. For a wall-mounted occupancy sensor, look at the Pass & Seymour PW-302 Wattstopper PIR dual-relay wall sensor instead.
7) What kind of load can I put on the relay output of this sensor?
The isolated relay is rated 1A at 30VAC/DC. That is a signalling contact, not a lighting contactor, so it is for telling a low-voltage lighting control panel or relay pack to switch. Feed ballast, driver, or fixture loads through the panel, not through the sensor contact.
8) Can I substitute a wall-mounted occupancy sensor for the Leviton OSC ceiling sensor?
No - they solve different openings. The Leviton OSC is a ceiling-mounted sensor intended for 8 to 20 foot mounting heights over the space it covers. The Pass & Seymour PW-302 Wattstopper is a PIR dual-relay wall occupancy sensor, mounted on the wall and switching two relay circuits, which suits rooms where you are replacing a wall switch rather than running low-voltage cable to a ceiling location. Choose the ceiling unit when the coverage pattern needs to come from overhead; choose the wall unit when the control point stays at the door.
9) Which ceiling occupancy sensor should I standardize on for a mix of private offices and small conference rooms?
For rooms in the 500 to 1000 sq ft range the Leviton OSC line covers both sizes with a single part family - OSC05-RUW for 500 sq ft and OSC10-RUW for 1000 sq ft - on 24VAC/VDC with a 1A 30VAC/DC isolated relay output and Title 24 compliance, so the wiring method and code documentation stay identical across the facility. Where a room runs larger than that, the Pass & Seymour UT3053 ultrasonic ceiling sensor is also 24V and covers 2000 sq ft, letting you keep ultrasonic technology across the whole building with only the coverage rating changing.
10) What ceiling sensor reduces false triggering from air movement compared with a straight ultrasonic unit?
The Leviton OSC is a single-technology ultrasonic ceiling sensor, which responds to changes in reflected sound waves. Where a space has strong HVAC airflow and you want a second confirmation before the lights switch, the Pass & Seymour DT300 Wattstopper is a dual technology ceiling occupancy sensor at 24V with 360 degree coverage, pairing two sensing methods in one head. A pure PIR option in ceiling form is the Pass & Seymour CI305, rated 360 degrees and 1200 sq ft.
11) Will the white housing match the other ceiling devices in my building?
The OSC sensors ship in Global White only, across both the 500 sq ft and 1,000 sq ft models, so a fleet of them across a floor will look consistent. There is no other color offered.
12) Is this sensor rated for an unconditioned space like a parking structure or a hot mechanical room?
Operating temperature is rated to 40 degrees Celsius (104 F), so it belongs in conditioned interior spaces. A mechanical room or an uncooled garage that routinely runs hotter than that is outside the rating. The unit is manufactured in Mexico.
