Key Features

  • Coverage Area: Monitors up to 1000 sq ft with 360° ultrasonic detection for comprehensive room coverage.
  • Voltage: Operates at 24V for compatibility with standard low-voltage occupancy sensing systems.
  • Flexible Operation: Automatic or manual-on operation when used with a BZ-150 Power Pack, accommodating varied facility lighting policies.
  • Low-Voltage Switch Input: Accepts low-voltage switch input for manual-on operation, giving occupants direct control when needed.
  • Walk-Through Mode: Increases energy savings potential by allowing brief occupancy to trigger shorter lighting run times.
  • Ultrasonic Diffusers: Provide more comprehensive coverage than standard sensors, improving detection accuracy across the space.
  • Low-Profile Design: Architecturally appealing low-profile appearance blends into ceiling installations.
  • Plug Terminal Wiring: Plug terminal wiring allows for quick and easy installation, reducing labor time on the job.

Pass & Seymour UT-305-2 – Frequently Asked Questions

1) How much floor area will one UT3052 ultrasonic ceiling sensor cover?
Up to 1000 sq ft with 360 degree detection from a ceiling mount position. For an open-plan floor or a large conference room, lay the sensors out so the 1000 sq ft circles overlap rather than stretching one head past its pattern.
2) Ultrasonic or PIR occupancy sensor for an office with cubicle partitions?
Ultrasonic is the one to use where partitions, bookcases or cubicle walls block line of sight. The UT3052 uses ultrasonic diffusers and detects fine motion, so someone typing at a desk behind a partition keeps the lights on. PIR heads need line of sight to a moving heat source, which is why they drop occupants in partitioned space. If the room is open and you want PIR, ZenSupply carries the Lithonia CM-9 low voltage PIR sensor and the Leviton ODS15-IDW self-adaptive PIR.
3) Can I set the UT3052 so lights come on manually instead of automatically?
Yes. Paired with a BZ-150 Power Pack the sensor runs automatic-on or manual-on, and it accepts a low-voltage switch input so occupants press a switch to turn lights on while the sensor still handles automatic shutoff. That manual-on arrangement is what many energy codes expect in offices and conference rooms.
4) I need a 120/277V ceiling or wall occupancy sensor that doesn't need a power pack - what should I buy instead?
The UT3052 won't do it; it's a 24V low-voltage head and has to run through a power pack. For a self-contained line voltage unit, ZenSupply carries the Leviton ODS10-ID PIR commercial grade sensor rated 120/277V AC, and the ODS10-ID-E version covering 2100 sq ft in black. The Lithonia CMR-9 PIR sensor comes with a relay as well.
5) What is the closest low-voltage ceiling occupancy sensor alternative to the Pass & Seymour UT3052?
The Lithonia Lighting CM-9 is the nearest low-voltage counterpart. It is a PIR occupancy sensor switch rated 12-24V AC/DC in white, so like the UT3052 at 24V it runs off a low-voltage control circuit rather than switching line voltage directly. The difference is sensing technology: the UT3052 uses 360-degree ultrasonic detection with ultrasonic diffusers to pick up fine motion, while the CM-9 is passive infrared and needs line-of-sight heat movement. In open offices and conference rooms with partitions or furniture breaking up sight lines, the ultrasonic UT3052 holds detection where a PIR head can drop out.
6) I do not want to add a power pack - what occupancy sensor should I use instead of the UT3052?
The UT3052 is a 24V low-voltage sensor that needs a BZ-150 Power Pack to switch a load and to enable automatic or manual-on operation. If you want the switching built in, look at a line-voltage device instead: the Leviton ODS10-ID is a PIR commercial grade occupancy sensor rated 120/277V AC, and the Lithonia CMR-9 is a PIR occupancy sensor with an integral relay. Both handle the load themselves, so the install is one device rather than a sensor plus a separate power pack in the ceiling.
7) Which sensor covers more square footage than the UT3052's 1000 sq ft?
The Pass & Seymour UT3052 is specified for up to 1000 sq ft with 360-degree ultrasonic coverage. For a larger open area off a single head, the Leviton ODS10-ID-E is rated 2100 sq ft and runs on 120/277V in a black finish. Note the trade: the Leviton unit is PIR, so coverage is dependent on line of sight to moving occupants, while the UT3052's ultrasonic detection responds to fine motion such as a seated worker over its smaller footprint.
8) What does walk-through mode do on a Wattstopper ultrasonic ceiling sensor?
Walk-through mode shortens the run time when someone only passes briefly through the space. If no further occupancy is detected shortly after entry, the lights drop out instead of holding the full time delay. It's worth enabling in corridors, copy rooms and restrooms where traffic is short and frequent.
9) Can I run more than one UT3052 sensor in a large open office?
Yes, multiple 24V heads are a normal way to cover a floor plate larger than one sensor's 1000 sq ft pattern. They tie back through the BZ-150 Power Pack arrangement that supplies the 24V and switches the lighting, so plan the power pack and circuit layout alongside the sensor spacing.
10) Is the Leviton ODS15-IDW a direct replacement for a Pass & Seymour UT3052?
No. The Leviton ODS15-IDW is a PIR self-adaptive commercial grade occupancy sensor, and the ODC0S-I1W is a PIR commercial grade line voltage sensor. Both are passive infrared devices, while the UT3052 is a 24V ultrasonic ceiling sensor using 360-degree ultrasonic diffusers. Swapping one in changes both the detection method and the control wiring, since the UT3052 sits on a low-voltage circuit with plug terminal wiring and a BZ-150 Power Pack rather than switching line voltage at the device.
11) For a commercial office energy code retrofit, how does the UT3052 compare to the Leviton commercial grade PIR sensors?
Both are aimed at commercial lighting control. The Leviton ODC0S-I1W and ODS10-ID are listed as commercial grade PIR sensors, with the ODC0S-I1W operating at line voltage and the ODS10-ID at 120/277V AC. The Pass & Seymour UT3052 approaches the same job from the low-voltage side: 24V, 360-degree ultrasonic coverage to 1000 sq ft, walk-through mode, and a low-voltage switch input for manual-on. If your retrofit already has a low-voltage control layer or you need manual-on behavior at the wall, the UT3052 fits that architecture; if you are replacing a line-voltage device in place, the Leviton units keep the existing wiring.
12) Is wiring the UT3052 sensor a hard-wire or plug connection?
Plug terminal wiring. The sensor lands on a plug terminal rather than individual screw terminations, which cuts time at the ceiling and makes swapping a head straightforward on a retrofit.
13) What is the exact part number to order for the Wattstopper 360 degree ultrasonic ceiling sensor?
Order by model UT3052, manufacturer part number UT-305-2, from Pass & Seymour's Wattstopper line. There is one configuration: 360 degree, 24V. Country of origin is China.
14) Will a low-profile ceiling sensor like this look acceptable in a finished conference room?
The UT3052 housing is a low-profile architectural design meant to sit flat against the ceiling rather than hang below it, which is why it gets specified in conference rooms and finished open-plan offices instead of back-of-house only.
