Pass & Seymour UT3051 Wattstopper Ultrasonic Ceiling-Mount Occupancy Sensor, 24V, 360° Coverage

The Pass & Seymour UT3051 Wattstopper Ultrasonic Ceiling Mount Occupancy Sensor delivers dependable 360° ultrasonic detection across spaces up to 500 sq ft, making it well suited for automated lighting control in commercial and light industrial environments. Operating on 24V, this ceiling-mount sensor pairs ultrasonic diffusers with a low-profile, architecturally appealing housing for discreet, unobtrusive installation. Plug terminal wiring simplifies setup, while a low-voltage switch input supports manual-on operation when the installation calls for it.

Key Features

  • 360° Coverage: Ultrasonic detection pattern covers up to 500 sq ft for comprehensive, room-wide occupancy monitoring.
  • 24V Operation: Accepts a low-voltage switch input, enabling manual-on operation alongside automatic sensing.
  • Ultrasonic Diffusers: Give more comprehensive coverage across the sensed area than standard sensor lenses.
  • Low-Profile Design: Architecturally appealing, unobtrusive ceiling-mount housing blends into finished spaces.
  • Walk-Through Mode: Increases energy savings potential by adapting sensor timeout behavior for brief occupancy events.
  • BZ-150 Power Pack Compatible: Enables automatic or manual-on operation when paired with a BZ-150 Power Pack.
  • Plug Terminal Wiring: Plug-style terminal connections allow quick, easy installation and simplified field wiring.

Pass & Seymour UT-305-1 – Frequently Asked Questions

1) Can the Pass & Seymour UT3051 occupancy sensor be wired directly to a 120V lighting circuit?
No. The UT3051 is a 24V low-voltage sensor, so it can't switch line voltage on its own. It needs a power pack to supply the 24V and do the switching, and the sensor is built to work with the BZ-150 Power Pack for either automatic-on or manual-on operation. If you want a sensor that wires straight into the line-voltage circuit at the ceiling, look at a line voltage unit like the Leviton ODC Series instead.
2) How big a room will the UT3051 ceiling sensor cover?
Up to 500 square feet, with a 360 degree ultrasonic detection pattern from the ceiling. That suits a private office, a small conference room, or a break room. For a large open work area you'd either use multiple units or step up to a higher-coverage sensor such as the Leviton PIR unit rated at 2100 square feet.
3) Can the UT3051 be set up so lights only come on when someone presses a switch?
Yes. The sensor accepts a low-voltage switch input, which lets you run it manual-on: occupants turn the lights on at the switch and the sensor turns them off when the space empties. Paired with a BZ-150 Power Pack it will do either automatic-on or manual-on. Manual-on is what many energy codes ask for in offices and conference rooms.
4) What is the difference between the Pass & Seymour UT3051 and a Leviton ODS10-ID occupancy sensor?
The UT3051 is an ultrasonic ceiling-mount sensor with 360 degree coverage running on a 24V low-voltage input, so it needs a power pack such as the BZ-150 to switch the lighting load. The Leviton ODS10-ID is a PIR commercial grade sensor rated 120/277V AC, so it is a line-voltage device rather than a low-voltage head. Choose the UT3051 when the design calls for low-voltage sensor wiring back to a power pack, and the ODS10-ID when the sensor is wired directly on line voltage.
5) Should I use an ultrasonic sensor or a PIR sensor for an office?
Ultrasonic, like the UT3051, senses motion by sound wave disturbance rather than line-of-sight heat, so it picks up minor movement and works where furniture, partitions, or restroom stalls block a direct view. PIR needs line of sight to the occupant but is less prone to false trips from air movement. If your space is open and unobstructed, a PIR unit such as the Leviton ODS10-ID is the simpler pick; for cubicles, partitioned offices, and restrooms, the ultrasonic pattern covers better.
6) How does the UT3051 terminate its wiring, and is it hard to install in a finished ceiling?
Wiring is plug-style terminal connections, so the low-voltage leads land without stripping and screwing individual terminals. The housing is low-profile ceiling-mount, which keeps it flush-looking in a finished office ceiling. Remember it is a 24V device, so your rough-in is low-voltage cable back to the power pack, not a line-voltage home run to the sensor.
7) Is the UT3051 a wall switch sensor or a ceiling unit?
It's a ceiling-mount sensor, mounted overhead for a full 360 degree pattern. It does not replace a wall switch box device. If you need something that drops into the existing switch box on a 120/277V circuit, a wall-mount unit like the Leviton ODS15-IDW self-adaptive sensor is the right category.
8) Is there a simpler alternative to the UT3051 that avoids running a separate power pack?
Yes. The UT3051 operates at 24V and relies on a BZ-150 power pack for automatic or manual-on switching of the load. The Leviton ODC0S-I1W is a PIR commercial grade line voltage occupancy sensor, so the switching is handled at the sensor and no low-voltage power pack is part of the circuit. The tradeoff is PIR line-of-sight detection in place of the UT3051's ultrasonic diffusers.
9) Will a Leviton ODS15-IDW work as a drop-in replacement for a UT3051?
No. The ODS15-IDW is a PIR self-adaptive commercial grade sensor, while the UT3051 is an ultrasonic sensor with a 24V input intended to feed a power pack. They are both commercial occupancy sensors, but the detection technology and the voltage arrangement differ, so the existing UT3051 wiring and BZ-150 power pack setup would not carry over unchanged. Treat the ODS15-IDW as a redesign of the control rather than a like-for-like swap.
10) For a restroom or partitioned office where partitions block line of sight, is the UT3051 or a PIR sensor the better choice?
The UT3051 uses ultrasonic diffusers for 360 degree detection over up to 500 sq ft, and ultrasonic sensing does not depend on an unobstructed view of the occupant, which suits spaces broken up by stalls or partitions. The Leviton ODC0S-I1W, ODS10-ID and ODS15-IDW are all PIR commercial grade sensors, which detect motion within their field of view. In open rooms with clear sightlines the PIR units apply directly; where partitions interrupt the view, the ultrasonic UT3051 is the fit.
11) What is walk-through mode on the UT3051 sensor?
Walk-through mode shortens the timeout when someone only passes briefly through the space, so the lights drop back off quickly instead of running the full delay. It's there to cut wasted runtime in corridors, copy rooms, and offices people step into for a moment.
12) Can I run more than one UT3051 off a single power pack to cover a bigger room?
Each UT3051 covers up to 500 square feet, so larger rooms are normally handled by adding sensors on the same low-voltage control circuit rather than by one unit. Confirm the sensor count against your BZ-150 Power Pack's rated low-voltage load before you lay out the room.
