Leviton Ceiling-Mount PIR Occupancy Sensor, 450 Sq Ft, 24VAC/VDC

The Leviton is a low-voltage, ceiling-mounted occupancy sensor built for automated lighting control across coverage areas up to 450 sq ft. Operating on 24VAC/VDC with true PIR (passive infrared) detection, this sensor pairs with a 1A 30VAC/DC isolated relay to switch lighting loads reliably. It ships with an Extra Mid-Range Lens Assembly designed for mounting heights between 8'-20', and it is both Title 24 Compliant and NAFTA Compliant, making it a strong fit for energy-code-driven commercial retrofits and new construction in a Global White finish. This model family is available as OSC04-I0W-P, OSC04-RIW, and OSC15-I0W-P configurations to match specific project requirements.

Leviton OSC04-I0W – Frequently Asked Questions

1) Can I wire this Leviton ceiling occupancy sensor straight to a 120V lighting circuit?
No. The Leviton OSC04 ceiling sensor is a low-voltage device running on 24VAC/VDC, so it has to be fed from a low-voltage power pack or a low-voltage lighting control system. Its output is a 1A 30VAC/DC isolated relay contact, not a line-voltage switch leg, so the power pack or relay panel does the actual load switching. If you need a device that sits in the wall box and switches line voltage directly, this is the wrong part.
2) Will a 450 sq ft PIR sensor cover my 1,000 sq ft open office?
Not on its own. At 450 square feet of coverage you would be zoning the space across multiple heads, or stepping up to a larger sensor. From the ceiling sensors we carry, the Pass & Seymour CI305 Wattstopper low-profile ceiling PIR is rated 1200 sq ft with 360 degree coverage, and the UT3053 Wattstopper ultrasonic ceiling sensor is rated 2000 sq ft at 24V. Both are single-head options for larger rooms.
3) Does this Leviton sensor satisfy California Title 24 automatic shutoff?
Yes. The sensor is listed as Title 24 Compliant, so it can be used to meet the automatic lighting shutoff requirement, and it is also NAFTA Compliant. It carries CUL/US certification. For submittals, note it is manufactured in Mexico.
4) What is the closest low-voltage ceiling PIR equivalent to the Leviton OSC04-I0W if I need a different brand on the same 24V control system?
The Pass & Seymour CI305 Wattstopper low-profile ceiling PIR occupancy sensor is the nearest match in sensing technology and mounting style - both are ceiling-mount passive infrared sensors. The Leviton OSC04-I0W runs on 24 volts and covers 450 square feet, while the CI305 is rated 360 degrees at 1200 square feet, so the Pass & Seymour unit suits a considerably larger open room from a single device.
5) I need coverage well beyond 450 square feet in an open ceiling area - what should I use instead of the Leviton OSC04?
The Leviton OSC04-I0W is specified for 450 square feet of coverage. For a much larger open space, the Pass & Seymour UT3053 Wattstopper ceiling-mount ultrasonic sensor is rated 24V, 360 degrees, and 2000 square feet. It uses ultrasonic rather than passive infrared detection, so it senses motion that is not in direct line of sight, which matters in rooms with partitions or furniture blocking the ceiling view.
6) Can I substitute the Pass & Seymour PW-302 for the Leviton OSC04 ceiling sensor?
No - they mount in different places. The Leviton OSC04-I0W is a ceiling-mount sensor covering 450 square feet. The Pass & Seymour PW-302 Wattstopper is a PIR dual-relay wall occupancy sensor, so it mounts on the wall and switches two relay circuits. If your drawing calls for a ceiling location and a low-voltage 24V tie-in, the PW-302 is not a drop-in; if you need two separately switched loads from one wall position, the PW-302 is the device that does it.
7) PIR or dual-technology for a conference room that goes dark for presentations?
PIR only sees heat movement in its line of sight, so seated occupants with little motion, or people behind a projector screen or partition, can drop out and take the lights with them. The Leviton OSC04 is a true PIR sensor. For rooms with long low-motion periods or obstructions, a dual-technology head like the Pass & Seymour DT300 Wattstopper (24V, 360 degree ceiling mount) adds a second sensing method to hold occupancy. PIR is the safer pick in spaces with air movement or HVAC diffusers nearby, where ultrasonic can false-trigger.
8) What is the difference between the Leviton OSC04-I0W-P, OSC04-RIW and OSC15-I0W-P?
Three models are offered in this family: OSC04-I0W-P, OSC04-RIW, and OSC15-I0W-P. The OSC04 versions are the 450 sq ft coverage sensors; the OSC15 is the alternate configuration in the same family. Order by the exact model code so you get the configuration your drawings call out, since all three share the Global White ceiling finish.
9) Can I use this Leviton ceiling sensor in an unheated warehouse or parking structure?
Operating temperature is specified at 0 degrees Celsius, which is freezing point, so this is an interior sensor for conditioned space. Unheated spaces that drop below freezing are outside its rating. Typical fits are offices, conference rooms, classrooms, and retail areas.
10) I need two lighting zones switched separately from one sensor. Will this Leviton work?
No. The OSC04 provides a single 1A 30VAC/DC isolated relay output, so it controls one switched zone. For two independently switched loads from one sensor, the Pass & Seymour PW-302 Wattstopper PIR dual-relay sensor is a dual-relay option, though it is a wall-mount device rather than ceiling mount.
11) Is a dual-technology sensor a better choice than the Leviton OSC04 PIR for a conference room with minor occupant movement?
The Leviton OSC04-I0W uses true passive infrared detection, which responds to motion in the sensor's line of sight. The Pass & Seymour DT300 Wattstopper is a dual technology ceiling sensor rated 24V, 360 degrees, combining more than one sensing method in one head. In rooms where occupants sit still for long stretches, buyers often specify dual technology; where the line of sight is clear and the room is at or under 450 square feet, the Leviton PIR unit is the simpler device on the same low-voltage supply.
12) For a California Title 24 lighting retrofit, which of these sensors is documented as code compliant?
The Leviton OSC04-I0W is listed Title 24 Compliant and NAFTA Compliant, and carries CUL/US certification. The Pass & Seymour comparables - the DT300 dual technology ceiling sensor, the CI305 ceiling PIR, the UT3053 ceiling ultrasonic, and the PW-302 wall sensor - are identified by series and sensing type. If the submittal has to show Title 24 automatic shutoff compliance on the sensor itself, the Leviton unit carries that designation.
13) Which ceiling sensor should I standardize on across a building with both small offices and large open areas?
A common approach is to pair devices by room size. The Leviton OSC04-I0W covers 450 square feet from the ceiling on 24VAC/VDC with a 1A isolated relay, suiting private offices and small conference rooms, and its Extra Mid-Range Lens Assembly supports mounting heights of 8 to 20 feet. For the open areas, the Pass & Seymour CI305 ceiling PIR is rated 1200 square feet at 360 degrees and the UT3053 ceiling ultrasonic is rated 2000 square feet at 24V. All are ceiling-mounted low-voltage devices, so the control wiring approach stays consistent.
