Pass & Seymour DSW302W Wattstopper Dual-Technology Multi-Way Occupancy Sensor with Dual-Relay Control, 120/277V, White

The Pass & Seymour Wattstopper Multi-Way Dual Technology Occupancy Sensor combines passive infrared and ultrasonic detection technologies to deliver high-sensitivity, dense-coverage occupancy sensing for commercial spaces. Built with two independent relays, this dual-technology sensor controls two separate lighting loads or circuits from a single device, and it defaults to Manual-ON operation to maximize energy savings. Rated for 120/277V operation (with 120/240/277 VAC and 347 VAC models also available in the Wattstopper line), this White, low-profile sensor is engineered for reliable, code-friendly lighting control in offices, conference rooms, corridors, and other multi-way switched spaces where dependable occupancy detection is required.

Key Features

  • Dual-Relay Control: Two independent relays allow control of two separate lighting loads or circuits from a single sensor, simplifying multi-way and multi-zone wiring.
  • Manual-ON Default: Defaults to Manual-ON operation for maximum energy savings, requiring occupants to manually turn lighting on while automatically shutting it off when a space is unoccupied.
  • Voltage Flexibility: Available in 120/277V, plus 120/240/277 VAC and 347 VAC models, to match a wide range of commercial electrical systems.
  • Dual Technology Detection: Combines passive infrared and ultrasonic sensing methods for high sensitivity and dense coverage, reducing false-offs and missed detections.
  • Low-Profile Design: Color-matched lens and low-profile housing create an appealing, unobtrusive appearance suited to modern interiors.
  • Finish: Matte White finish blends cleanly with common wall and ceiling finishes in commercial environments.

Pass & Seymour PAS-DSW-302-W – Frequently Asked Questions

1) Can the Pass & Seymour DSW302W occupancy sensor control two separate lighting circuits?
That is what the DSW302W is built for. It carries two independent relays, so one wall sensor can switch two separate lighting loads or circuits, which is how you split a conference room into a front and rear zone or keep task and general lighting on different circuits without adding a second sensor.
2) Will the DSW302W work on a 277V commercial lighting circuit?
Yes, the DSW302W is rated 120/277V, so it drops onto either a 120V branch circuit or a 277V commercial lighting circuit. If your building runs 347V or you need a 120/240/277 device, the Wattstopper line has separate models for those voltages, so specify the right one rather than assuming this part covers them.
3) Does this Wattstopper sensor turn lights on automatically when someone walks in?
No. The DSW302W defaults to Manual-ON, meaning occupants press the switch to turn lights on and the sensor handles turning them off when the space empties. If your spec calls for lights coming on by themselves on entry, this default is not what you want out of the box. Manual-ON is the setting most energy codes prefer in offices and private spaces, which is why it ships that way.
4) What is the difference between the DSW302W and a PIR-only occupancy sensor like the Leviton ODS15-IDW?
The DSW302W uses dual-technology sensing, combining passive infrared with ultrasonic detection for dense coverage in spaces where occupants may be out of direct line of sight. The Leviton ODS15-IDW is a PIR self-adaptive commercial grade occupancy sensor, relying on infrared detection alone. Rooms with partitions, stalls, or blocked sightlines are typically where the ultrasonic half of the DSW302W earns its place.
5) Is the Leviton ODC0S-I1W a direct substitute for the Pass & Seymour DSW302W?
Not directly. The Leviton ODC0S-I1W is a PIR commercial grade line voltage occupancy sensor, so it detects with infrared only and switches a single load. The DSW302W adds ultrasonic detection alongside PIR and carries two independent relays for two loads or circuits, plus a Manual-ON default. If the drawing calls for two switched circuits or dual-technology sensing, the ODC0S-I1W will not meet it.
6) Why choose a dual-technology occupancy sensor over a PIR-only one?
Dual technology means the DSW302W uses both passive infrared and ultrasonic detection. PIR needs line of sight and clear motion, so it can drop occupants sitting still at a desk or working behind a partition. Adding ultrasonic picks up smaller movement and works around obstructions, which cuts false-offs. In a wide-open corridor or a simple storage room with clear sightlines, a PIR-only sensor such as the Leviton ODS10-ID is usually enough and is the simpler device.
7) Is the DSW302W a wall switch sensor or a ceiling sensor?
It is a wall-mounted switch-style sensor with a low-profile housing and a color-matched lens, sized at 2.73 by 1.76 inches on the face with a 1.83 inch depth behind the plate. Plan on a standard wall box at the switch location, not a ceiling mount.
8) I need a plain single-load occupancy sensor for a small office. Is the dual-relay DSW302W overkill?
Probably. The DSW302W's value is its two independent relays for two circuits. For a single lighting load in a small room, a single-relay commercial sensor does the job with less wiring; the Leviton ODS10-ID is a commercial grade PIR sensor rated 120/277V, and the self-adaptive Leviton ODS15-IDW is another commercial grade option. Spend the money on the dual-relay device where you actually have two zones to switch.
9) What color and finish is the DSW302W, and will it match the other devices on the wall?
White with a matte finish, including the lens, which is color matched to the body. It sits alongside standard white commercial wiring devices and cover plates without standing out. Only the white version carries this part number, DSW-302-W, so if your building is standardized on ivory or black you need a different catalog number.
10) What is the exact part number for the white 120/277V dual-relay Wattstopper wall sensor?
DSW302W, ordered under manufacturer part number DSW-302-W from Pass & Seymour's Wattstopper line. That number gets you the dual-technology, dual-relay multi-way sensor in white at 120/277V. Country of origin is China.
