Pass & Seymour DSW301W Wattstopper Dual-Technology Occupancy Sensor, Single-Relay, 120/277V, White

The Pass & Seymour DSW301W is a Wattstopper multi-way dual-technology occupancy sensor built for single-relay lighting control at 120/277V. Finished in white, this sensor combines passive infrared and ultrasonic detection to reliably control lighting in spaces where a single technology can fall short, and it is designed to coordinate with additional units in multi-way switched circuits. Selectable operating modes, an audible pre-shutoff alert, and a vandal-resistant lens make it a practical choice for commercial spaces that demand dependable, code-driven lighting control.

Key Features

  • Dual-Technology Detection: Combines passive infrared and ultrasonic sensing for accurate occupancy detection across varied room conditions.
  • Selectable Walk-Through Mode: Turns lights off three minutes after initial occupancy if no additional motion is detected within the first 30 seconds, reducing wasted energy in transient spaces.
  • Automatic Mode Recovery: In automatic mode, the sensor returns to Auto-ON operation after lights are turned off manually, restoring hands-free control.
  • Audible Shutoff Alert: Selectable audible alert warns occupants of an impending shutoff, ideal for presentations and meetings.
  • Test Mode: Allows quick and easy adjustments during commissioning and troubleshooting.
  • Four Occupancy Logic Options: Customizable control logic to match specific application requirements.
  • Zero-Crossing Relay: Zero-crossing switching extends relay life for long-term reliability.
  • Vandal-Resistant Lens: Durable lens design combines precise coverage with resistance to damage in high-traffic commercial areas.
  • Single-Relay, Multi-Way Configuration: Rated for 120/277V single-relay operation and designed for multi-way switched lighting circuits.
  • Finish: White housing with a matte finish for a clean, unobtrusive appearance on ceilings and walls.

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

1) What is the difference between the Wattstopper DSW-301-W and DSW-302-W occupancy sensors?
Both are the same dual-technology Wattstopper sensor in white; the difference is the switching configuration. The DSW-301-W is the single-way version for a sensor controlling a circuit on its own. The DSW-302-W is the multi-way version, meant to coordinate with additional units on a multi-way switched lighting circuit, such as a room with switches at two entrances. Wire the 301 where there is one switch point, the 302 where there is more than one.
2) Will a Wattstopper DSW sensor work on both 120V and 277V lighting circuits?
Yes. The DSW dual-technology occupancy sensor is rated 120/277V, so the same part works on a 120V branch circuit in an office and a 277V circuit in a commercial or institutional building. That is one part number to stock for both voltages, which is why it suits facilities standardizing across mixed-voltage buildings. It is a single-relay device.
3) What is the difference between the Pass & Seymour DSW301W dual-technology sensor and a Leviton ODS10-ID occupancy sensor?
The Pass & Seymour DSW301W combines passive infrared with ultrasonic sensing, so it can pick up occupancy in rooms where motion is small or partly blocked from the sensor's line of sight. The Leviton ODS10-ID is a commercial grade PIR sensor, meaning it relies on infrared detection alone. Both are rated for 120/277V. For a private office or restroom stall area where a single technology can miss a seated occupant, the dual-technology DSW301W is the one to specify; for an open corridor or storage room with clear sight lines, the PIR-only ODS10-ID covers the same voltage range.
4) For a conference room where lights must not drop during a presentation, which sensor should I specify?
The Pass & Seymour DSW301W is the one that addresses that directly: it offers a selectable audible pre-shutoff alert that warns occupants before the lights go off, and dual-technology sensing that adds ultrasonic detection to catch the small movements of a seated audience. The Leviton ODS15-IDW is a self-adaptive PIR sensor and the ODS10-ID a commercial grade PIR sensor, both detecting by infrared motion only.
5) Can occupants be warned before the lights shut off during a meeting or presentation?
Yes. The DSW dual-tech sensor has a selectable audible pre-shutoff alert that warns occupants before the relay drops, so a presentation does not go dark without notice. It is selectable, so you can disable it in spaces where a beep is unwanted.
6) Does this sensor turn lights off quickly in a space people only pass through?
It has a selectable walk-through mode. If occupancy is detected but no further motion occurs within the first 30 seconds, the DSW sensor shuts the lights off three minutes after the initial detection. That keeps lights from running a full time delay when someone only steps into a storage room or crosses a lobby.
7) If someone shuts the lights off manually, does the sensor stay off or go back to automatic?
In automatic mode it recovers on its own. After the lights are switched off by hand, the DSW sensor returns to Auto-ON operation, so the next person entering gets lights without touching the switch. There are four occupancy logic options plus a test mode for commissioning, so you can set the behavior per room rather than accepting one default.
8) Is there a simpler PIR-only alternative to the Pass & Seymour Wattstopper DSW dual-technology sensor?
Yes. The Leviton ODS10-ID is a commercial grade PIR occupancy sensor rated 120/277V AC, and the Leviton ODC Series ODC0S-I1W is a commercial grade PIR line voltage sensor. Either handles straightforward single-technology infrared detection. You give up the ultrasonic half of the sensing that the Pass & Seymour DSW301W provides, along with its selectable walk-through mode, audible pre-shutoff alert and four occupancy logic options.
9) For a space where occupancy patterns vary a lot, is a self-adaptive sensor a better fit than the Pass & Seymour DSW301W?
The Leviton ODS15-IDW is a PIR self-adaptive commercial grade occupancy sensor, which adjusts its own time delay based on observed room use. The Pass & Seymour DSW301W instead gives the installer explicit control: four selectable occupancy logic options, a selectable walk-through mode that shuts off three minutes after initial occupancy if no further motion is seen in the first 30 seconds, and a test mode for commissioning. Choose the ODS15-IDW if you want the sensor to tune itself, and the DSW301W if you want to set the behavior yourself and add ultrasonic detection.
10) Which occupancy sensor holds up best in a high-traffic public area like a school corridor or gym?
The Pass & Seymour DSW301W carries a vandal-resistant lens designed for high-traffic commercial areas, plus a zero-crossing relay that extends relay life over many daily switching cycles. The Leviton ODC0S-I1W, ODS10-ID, ODS10-ID-E and ODS15-IDW are all commercial grade PIR sensors. If the concern is physical abuse to the lens specifically, the vandal-resistant lens on the DSW301W is the distinguishing feature.
11) Is this sensor tough enough for a school corridor or other high-traffic area?
The lens is vandal-resistant, which is the part that usually gets hit in schools, gyms, and public restrooms. The relay uses zero-crossing switching to extend contact life, which matters where lighting cycles many times a day. Housing is white with a matte finish so it stays unobtrusive on a wall or ceiling.
12) What are the physical dimensions of the Wattstopper DSW301W sensor?
It measures 2.73 in height, 2.73 in length, 1.76 in width, and 1.83 in depth as published. Check those against your gang space before ordering for a crowded multi-gang box.
13) What color options are there for this Wattstopper dual-tech sensor?
White only, in a matte finish. If the room needs a dark device to blend with a black ceiling grid or dark trim, the Leviton ODS10-ID-E is a black PIR commercial grade sensor rated 120/277V, though it is single-technology rather than dual-tech.
