Leviton WSWDR-H9W Wireless Wall-Mount Occupancy Sensor – Unused
This Leviton WSWDR-H9W wall-mount wireless occupancy sensor is designed for LevNet RF lighting control systems in commercial interiors.
Leviton built this sensor for spaces where pulling new control wiring is the real problem, not detection accuracy. It quietly harvests ambient light, reports occupancy over a 902 MHz RF link, and leaves the heavy lifting to compatible receivers elsewhere in the system.
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, while the unit itself remains clean, complete, and unused.
Product Overview
The WSWDR-H9W is part of Leviton’s LevNet RF platform and uses a self-powered PIR design to support wireless lighting control strategies. It communicates occupancy status via 902 MHz EnOcean-based RF and does not switch line voltage directly. Power is harvested through integrated solar cells, with provisions for backup power in low-light environments.
Why 902 MHz Endures
Leviton continues to actively market and support LevNet RF products operating in the 902 MHz band, including occupancy sensors, relays, and receivers used in contemporary commercial lighting control systems. Recent product literature and listings confirm that these systems remain applicable within control strategies designed to meet ASHRAE 90.1 and Title 24 requirements when correctly specified and installed.
The 902 MHz EnOcean band is particularly well-suited to self-powered wireless sensors. Its propagation characteristics support reliable indoor ranges of 50–150 ft while operating at extremely low energy levels, which aligns with solar-harvesting designs like the WSWDR-H9W. In dense commercial environments, this band is less congested than 2.4 GHz alternatives such as Zigbee or Bluetooth, reducing interference from Wi-Fi, mobile devices, and other consumer radios.
Support for 902 MHz EnOcean technology is not limited to Leviton. Other building automation manufacturers, including Reliable Controls and Contemporary Controls, have released or maintained 902 MHz EnOcean-compatible products as recently as 2024–2025, particularly for BACnet-based integration. This ongoing ecosystem support is a key reason the frequency remains relevant in long-service commercial installations.

Frequently Asked Questions
Does this sensor switch lighting loads directly?
No. The WSWDR-H9W reports occupancy wirelessly and must be paired with compatible LevNet RF or EnOcean receivers or controllers that handle load switching.
How is the sensor powered?
It is primarily self-powered using integrated solar cells. It can operate for limited periods in darkness and supports optional 24 VDC or CR2032 backup power for low-light environments.
What coverage area can it support?
Depending on the installed lens and mounting conditions, coverage ranges from roughly 1,600 sq ft to up to about 2,000 sq ft.
Is this suitable for very dark rooms or storage areas?
For spaces that remain dark for extended periods, the optional 24 VDC or battery backup should be used to maintain reliable operation.
Is this sensor unused?
Yes. This unit is unused, new old stock. Packaging shows storage wear, but the sensor itself has not been installed or put into service.
Designed to disappear into the wall and do its job for years, this Leviton sensor is ready to step back into service wherever reliable occupancy data still matters.
