Product Overview
Leviton OSC10-MAW Ceiling Occupancy Sensor – Multi-Tech, Unused
This is a Leviton OSC10-MAW low-voltage, ceiling-mount occupancy sensor designed for commercial lighting control systems using external 24 VDC power packs.
Where ceiling sensors earn their keep is in the quiet moments between footsteps. By combining passive infrared with ultrasonic detection, the OSC10-MAW was built to recognize both large movements and the subtle shifts that keep lights from shutting off on an occupied room.
Product Condition
Unused, new old stock. The sensor has never been installed or placed into service. The manufacturer’s packaging shows wear from storage, while the sensor itself remains clean, complete, and unused.
Product Overview
The Leviton OSC10-MAW is part of the OSC10 series of ceiling-mounted, multi-technology occupancy sensors. It uses passive infrared sensing for major motion combined with ultrasonic detection for minor motion, providing 360-degree coverage when mounted at typical commercial ceiling heights. The sensor requires a separate 24 VDC power pack, such as the Leviton OSP20 series, and does not switch line voltage directly.
Key Features
- Ceiling-mount occupancy sensor with combined PIR and ultrasonic detection
- 360-degree coverage pattern for open commercial spaces
- Rated for approximately 1,000 sq ft coverage at 8–12 ft mounting heights
- Low-voltage operation at 24 VDC, approximately 35 mA draw
- Self-adjusting sensitivity with manual adjustment capability
- Adjustable time delay from seconds to 30 minutes, including test mode
- Optional ambient light override via built-in photocell
- LED indicators for PIR and ultrasonic activity during setup
Applications
- Offices and conference rooms with seated occupants
- Classrooms and training spaces
- Cubicle areas and open-plan workspaces
- Restrooms and support spaces requiring reliable minor-motion detection
- Commercial retrofits using low-voltage occupancy sensors
- Multi-sensor lighting zones powered from a shared power pack
Frequently Asked Questions
Is this a line-voltage sensor?
No. The OSC10-MAW is a low-voltage sensor and must be powered by a compatible 24 VDC power pack.
Why does it use both PIR and ultrasonic sensing?
PIR detects major motion such as walking into a room, while ultrasonic sensing helps maintain occupancy detection during small movements like typing or seated activity.
What coverage area should I expect?
When mounted at 8–12 ft, the sensor is rated for roughly 1,000 sq ft. Coverage may be reduced by obstructions or higher ceiling heights.
Can this help meet energy code requirements?
When applied as part of a properly designed control system, this sensor type is commonly used in strategies aligned with ASHRAE 90.1 and Title 24 requirements.
Is this sensor unused?
Yes. This unit is unused new old stock and has never been installed.
Designed for the moments when rooms are occupied but barely moving, this ceiling sensor is ready to return to service wherever dependable detection still matters.
