Lithonia Lighting WSX-IV Passive Infrared Wall Switch Occupancy Sensor, 120-277V, Ivory

The Lithonia Lighting WSX-IV Passive Infrared Wall Switch Occupancy Sensor is a wall-mounted, Auto ON occupancy sensor designed to replace a standard toggle switch and automatically control connected lighting based on occupant presence. Using passive infrared (PIR) detection technology, this sensor provides a 20-ft detection range for accurate presence sensing within a room or work area. It is rated for 120-277-Volt AC operation, allowing it to support a broad range of commercial and residential lighting circuits. Finished in Ivory to coordinate with standard wall plates and switch trims, the WSX-IV mounts directly into a standard wall switch box for straightforward installation in both new construction and retrofit projects. By automatically switching connected lighting on when occupants are present, this sensor helps facilities reduce wasted lighting energy and simplify day-to-day lighting operation.

Key Features

  • Detection Range: 20-ft passive infrared detection range gives the sensor reliable coverage for standard-sized rooms, offices, and common areas.
  • PIR Sensing Technology: Passive Infrared (PIR) sensing combined with Auto ON operation automatically activates connected lighting as soon as occupancy is detected, eliminating the need to manually operate a switch upon entry.
  • Voltage Rating: 120-277-Volt AC voltage rating allows this sensor switch to be installed on a wide variety of commercial and residential branch circuits.
  • Wall Switch Form Factor: Designed to install in a standard wall switch location, allowing for simple retrofit of an existing toggle switch or installation in new construction wiring.
  • Ivory Finish: Ivory finish coordinates with standard wall plates and switch colors for a clean, consistent appearance.
  • Auto ON Operation: Automatically turns connected lighting on upon detected occupancy, supporting consistent, hands-free lighting control at the wall switch location.

Lithonia Lighting WSX PDT IV – Frequently Asked Questions

1) Can the Lithonia WSX wall switch occupancy sensor replace an existing toggle switch?
Yes. The WSX mounts into a standard wall switch box in place of a toggle switch, so it works for retrofit as well as new construction wiring. It controls the connected lighting automatically from that same switch location.
2) What is the difference between the WSX PIR and WSX PDT occupancy sensor?
Two sensing technologies are offered. The WSX-IV uses passive infrared (PIR) only, which detects heat and motion within line of sight. The WSX PDT IV is dual-technology, pairing more than one sensing method in the same wall switch housing. PIR is the straightforward choice for open rooms and offices where the sensor can see the occupant; dual-technology is what people specify where minor motion or blocked sight lines cause PIR-only units to drop out, such as restrooms with stalls.
3) Will the WSX occupancy sensor work on a 277V commercial lighting circuit?
Yes. The WSX is rated 120-277V AC, so it goes on 120V residential and light commercial branch circuits as well as 277V commercial lighting circuits without a separate model or a power pack for the switch leg itself.
4) Does the Lithonia WSX turn the lights on by itself or do you still have to press it?
Auto ON. The WSX energizes the connected lighting as soon as it detects occupancy, so nobody has to touch the switch on entry. If your energy code or your tenant requires manual-on (vacancy) operation, this Auto ON version is not the right pick.
5) How large a room will a 20-ft occupancy sensor cover?
The WSX has a 20-foot passive infrared detection range, which suits standard private offices, break rooms, restrooms, conference rooms and corridor segments. For large open-plan areas or high-bay spaces, one wall switch sensor at the door will leave dead zones, and a ceiling-mounted sensor with wider coverage is the better approach.
6) What exact part number do I order for the dual-technology ivory WSX?
Dual-technology in ivory is Lithonia Lighting part number WSX PDT IV. The PIR-only ivory version is WSX-IV. Technology is the only choice to make on the order; both are ivory.
7) Will the ivory WSX sensor match the existing switches and wall plates in my building?
The WSX-IV and WSX PDT IV are both finished in ivory, which coordinates with standard ivory wall plates and devices. If your building is standardized on white or almond trim, the ivory face will read as a mismatch on that wall.
