Pass & Seymour PW311W Wattstopper Multi-Way PIR Wall-Mount Occupancy Sensor, 0-10V Dimming, White

The Pass & Seymour PW311W is a Wattstopper multi-way passive infrared (PIR) wall-mounted occupancy sensor with a single-relay, 0-10V dimming output, finished in White with a Matte surface. Designed to replace a standard wall switch, it detects room occupancy and automatically controls connected lighting, while its 0-10V dimming capability allows integration with dimmable fixtures for finer light-level control. The multi-way configuration lets multiple PW311W units coordinate detection and switching across a single lighting zone, making it a practical retrofit for commercial spaces seeking automatic, energy-conscious lighting control.

Key Features

  • Multi-Way PIR Detection: Passive infrared sensing coordinates occupancy detection across multiple wall-mounted sensors on the same lighting zone.
  • Single-Relay, 0-10V Dimming Control: Automatically switches lighting on and off while supporting 0-10V dimming for compatible fixtures.
  • Optional Smart Light Level: Adapts the ambient light hold-off threshold to meet user needs, avoiding unnecessary lighting operation when daylight is sufficient.
  • Test Mode: Allows quick and easy verification of sensor coverage during installation and commissioning.
  • Selectable Presentation Mode: May be deactivated to allow Auto-ON operation after a 15 second time delay.
  • LED Occupancy Indicator: A visible LED indicates occupancy detection for easy status confirmation.
  • Vandal-Resistant Lens: Combines precise detection coverage with a durable, vandal-resistant lens construction.
  • Selectable Walk-Through Mode: Turns lights off three minutes after the room is initially occupied if no further motion is detected after the first 30 seconds, with selectable audible and/or visual alerts for impending shutoff.

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

1) Can the Pass & Seymour PW311W replace an existing wall switch in a standard switch box?
The PW311W is built to go in where a standard wall switch was, so it mounts in the existing switch box and controls the lighting from the same location. The sensor body measures 2.73 x 2.73 x 1.75 x 1.81 inches per the published height, length, width and depth figures, so it sits in a single-gang opening. It is a wall-mounted configuration, not a ceiling sensor.
2) Does the PW311W occupancy sensor dim lights or just switch them on and off?
Both. The PW311W has a single relay that switches the load on and off plus a 0-10V dimming output, so it can drive dimmable drivers and ballasts that accept a 0-10V control signal. If your fixtures are not 0-10V dimmable, the dimming output simply goes unused and you get occupancy switching only.
3) I need occupancy sensing at two switch locations in one room. Can I use more than one PW311W on the same lighting zone?
That is exactly what the multi-way part means. Multiple PW311W units coordinate detection and switching across a single lighting zone, so you can put a sensor at each entry of a conference room or a long corridor and have them share occupancy information rather than fight each other.
4) Will the PW311W turn lights on automatically, or does someone have to press it?
Out of the box it runs in presentation mode, which holds the lights until a user acts. Deactivate presentation mode and the sensor switches to Auto-ON after a 15 second time delay. That makes it workable for restrooms and hallways where hands-free operation is expected, and for conference rooms where you want manual-on so a projector presentation is not interrupted.
5) What is the closest alternative to the Pass & Seymour PW311W if I need a wall-mount PIR occupancy sensor but not 0-10V dimming?
The PW311W is a wall-mounted passive infrared occupancy sensor with a single-relay 0-10V dimming output, so it is aimed at dimmable fixtures. If the fixtures are switched only, the Leviton ODS10-ID is a PIR commercial grade occupancy sensor rated 120/277V AC that provides straight line-voltage switching. The Leviton ODC0S-I1W is also a PIR commercial grade line voltage occupancy sensor. Both handle on/off control of the load without a 0-10V dimming lead to terminate.
6) I have a low-voltage lighting control panel instead of switched line voltage - is the PW311W the right sensor?
The PW311W is built to replace a standard wall switch and carries a single relay with a 0-10V dimming output. For a low-voltage control system where the sensor reports to a panel or relay pack, the Lithonia Lighting CM-9 is a PIR low voltage occupancy sensor switch rated 12-24V AC/DC. If the low-voltage sensor needs to switch its own load, the Lithonia CMR-9 is a PIR occupancy sensor with a relay. Confirm which arrangement the control drawing calls out before ordering.
7) Can I mix a Pass & Seymour PW311W with Leviton ODS or Lithonia CM sensors on the same multi-way zone?
No. The PW311W multi-way feature coordinates detection and switching across multiple PW311W units on a single lighting zone, so the companion devices on that zone need to be PW311W sensors. The Leviton ODS10-ID and ODS15-IDW are commercial grade PIR sensors and the Lithonia CM-9 is a low voltage PIR sensor switch - they are separate control platforms and do not join the PW311W multi-way group. Keep a multi-way zone on one family.
8) Will a PIR occupancy sensor keep lights on in a daylit office with windows?
The PW311W has an optional Smart Light Level feature that adapts the ambient light hold-off threshold, so the sensor can skip turning lights on when daylight in the space is already sufficient. It is a per-unit setting, so you can enable it on perimeter rooms with glazing and leave it off on interior rooms and corridors.
9) How do I verify sensor coverage after installing a PW311W?
The sensor includes a test mode for checking coverage during installation and commissioning, and an LED occupancy indicator that lights when motion is detected, so one person can walk the room and confirm the detection pattern. Walk the far corners and seated positions, not just the doorway, since passive infrared responds to movement across the lens.
10) Is the PW311W tough enough for a public restroom or school corridor?
The lens is a vandal-resistant construction, which is the reason this sensor shows up in restrooms, hallways and other unsupervised spaces. The housing is White with a matte finish, so it blends with standard white device plates rather than drawing attention.
11) What is walk-through mode on the PW311W and when should I enable it?
Walk-through mode shuts the lights off three minutes after the room is first occupied if no further motion is seen in the first 30 seconds, with selectable audible and/or visual warning before shutoff. Use it on spaces people enter briefly, like a storage room or copy room, so a quick in-and-out does not leave the lights burning for a full time delay.
12) Do I need a wall-mount sensor like the PW311W, or a ceiling-mounted occupancy sensor?
A wall-mount unit like the PW311W is the retrofit answer: it drops into the existing switch box and needs no new ceiling penetration or added wiring run, which suits single-entry rooms, restrooms and small offices. Go to a ceiling sensor when the room is large, L-shaped, or has partitions or stall walls that block a line of sight from the switch location, since passive infrared needs an unobstructed view of the motion. ZenSupply carries ceiling and low-voltage options in that case, including the Lithonia Lighting CM-9 low voltage sensor switch and the CMR-9 PIR sensor with relay.
13) For a large open area like a 2000 square foot space, should I use the PW311W or a ceiling-type sensor?
The PW311W is a wall-mounted sensor sized for rooms where a single switch location sees the whole space - restrooms, hallways, and conference rooms are the typical applications. For larger floor areas, the Leviton ODS10-ID-E is a PIR commercial grade occupancy sensor rated for 2100 square feet at 120/277V, in black. The Leviton ODS15-IDW is a PIR self-adaptive commercial grade sensor if you want the sensor to tune its own timing to traffic patterns.
14) Is the PW311W a commercial grade sensor or should I specify a Leviton ODS for a commercial job?
The PW311W is intended for commercial and office lighting control and uses a vandal-resistant lens, with test mode and selectable walk-through and presentation modes for commissioning. The Leviton ODC0S-I1W, ODS10-ID, ODS10-ID-E, and ODS15-IDW are all listed as commercial grade PIR sensors. The decision usually comes down to the output you need: the PW311W carries a 0-10V dimming output, while the Leviton ODC0S-I1W is a line voltage sensor.
15) What color and finish does the PW311W come in, and will it match my other devices?
One configuration is offered, model PW311W in White with a matte finish, so it sits alongside standard white wiring devices and plates. If a facility is standardized on black or ivory device fronts, the sensor will not match, and a black commercial PIR such as the Leviton ODS10-ID-E is the closer visual fit.
16) What is the exact part number and manufacturer line for the PW311W sensor?
It is sold under the Pass & Seymour line as part number PW-311-W, catalog designation PW311W, using Wattstopper occupancy sensing technology. Country of origin is China. Full electrical data is on the manufacturer spec sheet linked with the product.
