Leviton Multi-Technology PIR/Ultrasonic Occupancy Sensor, 24V DC

The Leviton Multi-Technology (PIR/Ultrasonic) Low Voltage Occupancy Sensor combines passive infrared and ultrasonic detection for accurate, false-trigger-resistant lighting control across a 1000-sq-ft coverage area. Engineered for 24-Volt DC low-voltage systems, this sensor is available in the OSC10-M0W-P and OSC20-M0W-P models and finished in a clean Off White housing to blend into ceiling and wall installations. Combining two detection technologies helps ensure lights respond reliably to both major motion and fine occupant movement, reducing wasted energy in unoccupied spaces.

Key Features

  • Coverage Area: Rated for 1000-sq-ft coverage, suitable for open offices, classrooms, and multipurpose rooms.
  • Multi-Technology Detection: Combines PIR and Ultrasonic sensing for dependable occupancy detection and reduced false-offs.
  • Low Voltage Operation: Operates on 24-Volt DC for compatibility with low-voltage lighting control systems.
  • Available Models: Offered as OSC10-M0W-P and OSC20-M0W-P to match project sensing requirements.
  • Finish: Off White housing for a clean, unobtrusive ceiling or wall appearance.

Technical Specifications

Leviton OSC20-M0W – Frequently Asked Questions

1) Can I wire the Leviton OSC10-M0W occupancy sensor straight to a 120V lighting circuit?
No. The Leviton Multi-Technology occupancy sensor runs on 24V DC low voltage, so it has to be fed from a low-voltage power pack or a lighting control system that supplies 24V DC and does the line-voltage switching. If you need a sensor that switches the load directly at line voltage, this is not the part.
2) What is the closest dual-technology equivalent to the Leviton OSC10-M0W-P from another brand?
The Pass & Seymour DT300 Wattstopper Dual Technology Ceiling Occupancy Sensor is the nearest match. Like the Leviton OSC10-M0W-P and OSC20-M0W-P, it pairs two detection technologies and runs on 24V, and it is specified for 360-degree ceiling coverage. The Leviton multi-technology sensor combines PIR and ultrasonic detection at a 1000-sq-ft coverage rating on 24V DC low-voltage control, in an Off White housing.
3) I need more than 1000 sq ft of ceiling coverage - what should I use instead?
For a larger open area, the Pass & Seymour UT3053 Wattstopper Ceiling Mount Ultrasonic Occupancy Sensor is rated for 2000 sq ft with 360-degree coverage and also operates at 24V. It is ultrasonic only, where the Leviton OSC10-M0W-P and OSC20-M0W-P combine PIR and ultrasonic across a 1000-sq-ft area on 24V DC.
4) Why choose a dual-technology PIR/ultrasonic sensor instead of a plain PIR sensor?
PIR alone needs line of sight and reacts mainly to larger motion, so lights can drop out on someone sitting still at a desk or behind a partition. The Leviton multi-tech sensor adds ultrasonic sensing to catch fine movement and cut false-offs, which is why it suits offices and classrooms. If the space is a corridor or a small open room where line-of-sight motion is obvious, a straight PIR ceiling unit like the Pass & Seymour CI305 Wattstopper low-profile 360 degree sensor, rated 1200 sq ft, is the simpler choice.
5) What is the difference between the Leviton OSC10-M0W-P and OSC20-M0W-P?
Both are Leviton Multi-Technology PIR/ultrasonic 24V DC sensors in Off White. They are the two models offered so you can match the sensing requirement of the space; order by model number, OSC10-M0W-P or OSC20-M0W-P, since the part numbers are not interchangeable on a submittal.
6) Is a Leviton 24V DC occupancy sensor a drop-in for a Wattstopper low-voltage ceiling sensor?
Electrically they sit in the same place in a system: the Pass & Seymour DT300 Wattstopper dual technology ceiling sensor is also a 24V, 360 degree dual-tech unit, so it serves the same role off a low-voltage power pack. Mounting footprint and connector arrangement differ between brands, so treat it as an equivalent function rather than a plate-for-plate swap.
7) I need a sensor that controls two separate lighting loads in one room. Is this it?
The Leviton OSC multi-tech sensor is a single low-voltage sensing head; switching is handled by whatever 24V DC power pack or control system it feeds. For a self-contained wall unit that switches two loads, look at the Pass & Seymour PW-302 Wattstopper PIR dual-relay wall occupancy sensor instead.
8) Which 24V low-voltage occupancy sensors can I standardize on across a building?
Three 24V options cover most room types: the Leviton OSC10-M0W-P and OSC20-M0W-P multi-technology PIR/ultrasonic sensors at 1000 sq ft for offices, classrooms and conference rooms; the Pass & Seymour DT300 Wattstopper dual technology ceiling sensor with 360-degree coverage; and the Pass & Seymour UT3053 Wattstopper ultrasonic ceiling sensor at 2000 sq ft for larger open spaces. All three are specified at 24V, so they suit the same low-voltage control infrastructure.
9) If I only need basic motion sensing in a ceiling, what is a simpler alternative to a multi-technology sensor?
The Pass & Seymour CI305 Wattstopper Low-Profile Ceiling PIR Occupancy Sensor uses passive infrared alone with 360-degree coverage rated to 1200 sq ft. The Leviton OSC10-M0W-P and OSC20-M0W-P add ultrasonic sensing alongside PIR, which is aimed at picking up fine occupant movement as well as major motion. Single-technology PIR relies on line of sight to the occupant; dual-technology is the usual choice where partitions or small movements are a factor.
10) Can I substitute a Wattstopper PW-302 wall sensor for the Leviton OSC10-M0W-P?
Not as a direct swap. The Pass & Seymour PW-302 Wattstopper is a PIR dual-relay wall-mounted occupancy sensor, so it mounts in the wall box and switches two relays using passive infrared only. The Leviton OSC10-M0W-P and OSC20-M0W-P are multi-technology PIR/ultrasonic sensors running on 24V DC low-voltage control with a 1000-sq-ft coverage rating, intended for ceiling or wall placement within a low-voltage lighting control system. Confirm the mounting location and control wiring before treating one as a replacement for the other.
11) Will this Leviton sensor match the off white devices already in my building?
The housing is Off White, meant to sit quietly on a ceiling or wall without contrasting against typical off white plates and tile grid. It is the only finish Leviton offers on these two models.
12) Can these Leviton occupancy sensors be used on a retrofit, or only new construction?
Both. Leviton lists these multi-tech sensors for new construction and for retrofit occupancy sensing upgrades in offices, classrooms, corridors, restrooms and common areas. The requirement on a retrofit is the same as new work: a 24V DC low-voltage supply and switching pack must be present or added.
