Pass & Seymour DW311W Wattstopper Dual-Technology Wall-Mount Occupancy Sensor, 0-10V Dimming, White

The Pass & Seymour DW311W Wattstopper dual-technology wall-mounted occupancy sensor combines high sensitivity with dense coverage for exceptional detection performance in commercial spaces. Rated for 120/277V operation and equipped with 0-10V dimming control, this sensor defaults to Manual-ON operation to maximize energy savings while supporting Partial-ON operation for energy code compliance or utility incentive programs. Finished in White with a color-matched, low-profile lens, the DW311W integrates cleanly into interior spaces while supporting fully functional multi-way control from up to four switch locations.

Key Features

  • Dual-Technology Detection: High sensitivity and dense coverage deliver exceptional occupancy detection performance.
  • 0-10V Dimming Control: Supports 0-10V dimming for compatible lighting fixtures, enabling flexible lighting control strategies.
  • Voltage Rating: Operates on 120/277V, suitable for standard commercial electrical systems.
  • Partial-ON Operation: Supports Partial-ON operation for energy code compliance or utility incentive eligibility.
  • Manual-ON Default: Defaults to Manual-ON operation for maximum energy savings.
  • Multi-Way Switch Control: Allows fully functional multi-way control from up to four switch locations.
  • Color-Matched, Low-Profile Lens: Color-matched lens and low-profile design provide an appealing, unobtrusive appearance.
  • Finish: Matte White finish blends with common wall and ceiling finishes.

Pass & Seymour DW-311-W – Frequently Asked Questions

1) Will the Pass & Seymour DW311W work on both 120V and 277V circuits?
Yes. The DW311W is rated 120/277V, so the same part number covers both standard commercial branch circuit voltages. That means you can standardize one sensor across a building with 120V office lighting and 277V corridor or high-bay panels instead of stocking two devices.
2) Does the DW311W dim the lights or just switch them on and off?
It provides 0-10V dimming control, so it drives dimmable 0-10V LED drivers or ballasts rather than only switching load. The fixtures themselves have to accept a 0-10V control signal; if your fixtures are line-voltage switched only, a dimming sensor like this one gains you nothing and a switching occupancy sensor is the right part.
3) Can I use this sensor in a room that has switches in more than one place?
Yes. The DW311W supports fully functional multi-way control from up to four switch locations, so a conference room or classroom with switches at two or three doors can keep all of them live. The companion locations are standard multi-way control points, not additional sensors.
4) Does the DW311W turn lights on automatically when someone walks in?
Out of the box it does not. The sensor defaults to Manual-ON, meaning the occupant presses the button to turn lights on and the sensor handles turn-off. It can also be set for Partial-ON, which brings lights up to a reduced level on entry. Manual-ON and Partial-ON are the modes energy codes and utility rebate programs typically call for, which is why it ships that way.
5) What is the difference between the Pass & Seymour DW311W and a PIR-only wall sensor like the Leviton ODS10-ID?
Detection technology is the dividing line. The DW311W is a dual-technology wall-mount occupancy sensor, pairing two sensing methods for high sensitivity and dense coverage, and it carries 0-10V dimming control plus Manual-ON default with Partial-ON capability. The Leviton ODS10-ID is a PIR commercial grade occupancy sensor rated 120/277V AC, so it relies on passive infrared motion alone. For an enclosed office or conference room where occupants sit still for long stretches and partition walls block line of sight, the dual-technology DW311W holds the lights on; where motion is obvious and frequent, PIR-only sensing like the ODS10-ID covers it.
6) I need dimming control, not just on/off switching. Which of these sensors does that?
The Pass & Seymour DW311W is the one specified with 0-10V dimming control, letting it drive compatible 0-10V drivers and ballasts rather than only switching the load. The Leviton ODS10-ID and the self-adaptive Leviton ODS15-IDW are commercial grade PIR occupancy sensors, and the Lithonia CMR-9 is a PIR occupancy sensor with relay - relay output is a switched contact, which is on/off control. If the fixture schedule calls for dimming, the DW311W is the device that matches it.
7) What does dual-technology mean on this sensor, and why would I pick it over a PIR-only sensor?
Dual-technology means the DW311W uses more than one sensing method together for high sensitivity and dense coverage, so it holds detection on small movements, like someone typing at a desk, better than motion-only sensing. PIR-only devices need line of sight motion. If your space is a private office, classroom or restroom where occupants sit still, dual-tech is the safer pick; for a corridor with clear through-traffic, a PIR unit such as the Leviton ODS10-ID (120/277V AC) or the Lithonia CMR-9 is enough.
8) What are the alternatives if I do not need 0-10V dimming?
For switching only, the Leviton ODS10-ID is a PIR commercial grade sensor rated 120/277V, and the Leviton ODS15-IDW is a self-adaptive PIR commercial grade unit. The Lithonia CMR-9 is a PIR sensor with a relay, and the Lithonia CM-9 is a low voltage PIR switch running on 12-24V AC/DC, so the CM-9 needs a separate power pack rather than wiring straight to a 120 or 277V circuit like the DW311W.
9) Is the Leviton ODS15-IDW self-adaptive sensor equivalent to the DW311W?
They solve overlapping problems differently. The Leviton ODS15-IDW is a PIR self-adaptive commercial grade occupancy sensor, meaning it tunes its own sensitivity and timing to the space over time. The Pass & Seymour DW311W instead uses dual-technology sensing for high sensitivity and dense coverage, and adds 0-10V dimming, Manual-ON default, Partial-ON operation for energy code or utility incentive programs, and fully functional multi-way control from up to four switch locations. If the opening is a three- or four-way switched room with dimmed fixtures, the DW311W addresses it directly.
10) Will the white DW311W match the other devices and plates on my walls?
The finish is White in a matte texture, with a color-matched low-profile lens so the sensor window does not read as a dark spot on the wall. That matches standard white commercial wiring devices and plates. If your building is standardized on ivory or black, this one will not blend; the Leviton ODS10-ID-E is a black PIR unit, though it is switching rather than 0-10V dimming.
11) Where can I get the wiring diagram and coverage data for the DW311W?
Pass & Seymour publishes a spec sheet for the DW311W that carries the wiring and performance detail. It is linked in the product documentation for the sensor under PDF: Spec Sheet. Pull that before rough-in if you are coordinating 0-10V control wiring back to the drivers.
12) Is the DW311W a commercial grade sensor or a residential one?
It is built for commercial lighting control: 120/277V operation, 0-10V dimming, Partial-ON for energy code compliance, and multi-way support. Typical placements are offices, classrooms, conference rooms, hallways and common areas, including code-driven retrofits. The Wattstopper dual-technology sensing is the commercial lighting control platform, not a residential motion switch.
