Product Overview
Low-Profile LevNet RF Occupancy Sensor for Discreet Retrofits – Unused
For facilities using Leviton LevNet RF lighting controls, the WSC12-M9N is a self-powered, surface-mount PIR occupancy sensor that reports minor and major motion over 902 MHz wireless to compatible receivers and controllers.
This sensor exists for the real-world retrofit: finished ceilings, busy tenants, and “no, we are not opening that wall.” Mount it where it belongs, pair it to the LevNet RF ecosystem, and let occupancy data travel by radio instead of conduit.
Product Condition
Unused, new old stock. The sensor has never been installed or placed into service. The manufacturer’s packaging shows signs of storage wear.
Product Overview
The Leviton WSC12-M9N is a LevNet RF 902 MHz wireless occupancy sensor with integrated solar energy harvesting. It is designed for surface mounting on ceilings or walls where a low-profile installation is preferred. The sensor communicates occupancy status to compatible LevNet RF receivers and does not switch line-voltage loads directly. For low-light or zero-light locations, the sensor supports backup powering via a 24 V connection or a battery backup option.
Key Features
- LevNet RF wireless occupancy sensor using 902 MHz communication
- Self-powered operation using integrated solar cells
- PIR detection for occupancy reporting (minor and major motion)
- Surface-mount, low-profile form factor for discreet installations
- Field-of-view rated up to 1,200 sq ft (application dependent)
- Configurable time delay for lighting control sequences (system dependent)
- Backup power provisions for low-light or zero-light environments (24 V connection or battery backup option)
- Designed to pair with compatible LevNet RF receivers, relays, and room controllers
Applications
- Commercial office lighting retrofits where new wiring is impractical
- Hallways and support spaces needing surface-mount occupancy detection
- Restrooms and utility areas using RF receivers located elsewhere
- Drop-ceiling environments where low profile and minimal disruption matter
- Hybrid projects mixing wired power packs and wireless LevNet RF zones
- Spaces targeting energy-code-aligned control strategies when properly designed and installed
Frequently Asked Questions
Does the WSC12-M9N switch a lighting load by itself?
No. This sensor reports occupancy wirelessly and must be paired with compatible LevNet RF receivers or controllers that perform the actual load switching.
How is this sensor powered?
It is designed to harvest energy from ambient light using integrated solar cells. For low-light or zero-light areas, it supports backup powering via a 24 V connection or a battery backup option.
What coverage area can it support?
It is rated for up to about 1,200 sq ft field-of-view in typical ceiling applications, but real coverage depends on mounting location, layout, and obstructions.
Is this compatible with a standard 24 V power pack like the OSP20-DA0?
Not directly as a wired sensor. The WSC12-M9N is part of the LevNet RF wireless ecosystem and is intended to work with LevNet RF receivers and controllers rather than functioning as a hardwired low-voltage sensor.
Is this sensor unused?
Yes. This is unused new old stock. Packaging shows storage wear, and the sensor has not been installed or placed into service.
Built for finished spaces and quiet upgrades, this Leviton wireless sensor is ready to be the missing link in a LevNet RF room that still needs reliable occupancy data.
