Pass & Seymour Wattstopper CI-300 Low-Profile PIR Ceiling Occupancy Sensor, 360°

The Pass & Seymour Wattstopper CI-300 is a Passive Infrared (PIR) ceiling-mount occupancy sensor that automatically turns lighting on and off based on room occupancy. It mounts flush to the ceiling with a low-profile, architecturally appealing design and delivers full 360° coverage, making it well suited for offices, corridors, and other commercial spaces where automated lighting control is needed.

Key Features

  • 360° Coverage: Passive infrared detection provides full-circle occupancy sensing from a single ceiling-mount location.
  • Low-Profile Design: Architecturally appealing, flat ceiling-mount appearance blends into finished spaces.
  • Walk-Through Mode: Increases energy savings potential by adjusting sensor response for brief occupancy events.
  • Plug Terminal Wiring: Simplifies and speeds up installation with quick-connect wiring terminals.
  • Low-Voltage Switch Input: Accepts a low-voltage switch input to enable manual-on operation.
  • Power Pack Compatible: Supports automatic or manual-on operation when paired with a BZ-150 Power Pack.

Technical Specifications

  • Product Line: Pass & Seymour
  • Country of Origin: China
  • Packaging: 80 EA

Typical Applications

  • Commercial Office and Corridor Lighting Control
  • Automatic Occupancy-Based Lighting Systems
  • Energy-Saving Retrofit Lighting Upgrades
  • New Construction Ceiling-Mount Sensor Installations
  • Multi-Sensor Lighting Zones Using a Shared Power Pack

Why Pass & Seymour?

Pass & Seymour's Wattstopper CI-300 sensor combines a low-profile design with reliable 360° passive infrared detection, giving facility managers and electrical contractors a straightforward way to automate lighting control. Plug terminal wiring and Power Pack compatibility make it a practical choice for both new installations and lighting retrofits focused on energy savings.

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

1) Does the Wattstopper CI-300 ceiling sensor switch the lights by itself, or do I need a power pack?
The CI-300 is a low-voltage sensor, not a line-voltage switch. It needs a BZ-150 Power Pack to actually switch the lighting load, and that pairing is what gives you automatic-on or manual-on operation. Budget the power pack into every CI-300 install. If you want a sensor that switches line voltage directly with no separate pack, look at the Lithonia CMR-9, which is a PIR occupancy sensor with a relay built in.
2) Will one CI-300 cover a whole office, or do I need sensors in each corner?
Coverage is a full 360 degrees from the single ceiling-mount position, so the pattern radiates in every direction instead of facing one way like a wall or corner-mount unit. That suits open offices, corridors and lobbies where the sensor sits centrally in the ceiling. Being passive infrared, it works on line of sight to body heat, so partitions, tall shelving and separate rooms each need their own sensor rather than relying on one unit to see around an obstruction.
3) Can occupants still turn the lights on manually with the CI-300?
Yes. The sensor accepts a low-voltage switch input, which is what enables manual-on operation, so occupants press a switch to turn lights on and the sensor handles turn-off on vacancy. That is the configuration most commercial energy codes expect in offices. Without that switch wired in, it runs automatic-on from occupancy detection.
4) What is the closest alternative to the Pass & Seymour Wattstopper CI-300 ceiling sensor if I need a low-voltage PIR sensor?
The Lithonia Lighting CM-9 is a PIR low voltage occupancy sensor switch rated 12-24V AC/DC in white, which puts it in the same low-voltage class as the CI-300. The CI-300 is a passive infrared ceiling sensor with 360 degree coverage that works with a BZ-150 Power Pack to supply its low-voltage power and switch the line-voltage load, so compare how each one is powered before you swap one for the other.
5) I need a sensor that wires directly to 120/277V instead of the CI-300 ceiling sensor. What should I order?
The Leviton ODS10-ID is a PIR commercial grade occupancy sensor rated 120/277V AC, and the ODS10-ID-E is the same voltage range with 2100 sq. ft. coverage in black. Both take line voltage directly, whereas the Wattstopper CI-300 is a low-voltage ceiling-mount PIR with a low-voltage switch input and plug terminal wiring.
6) Can I put several ceiling sensors on one lighting zone?
Yes. Multiple CI-300 sensors can feed a shared power pack to cover one lighting zone, which is how you handle a long corridor or an L-shaped room where a single 360 degree pattern cannot see the whole space. The low-voltage wiring between sensors and the pack keeps the line-voltage work at one point in the circuit.
7) What is walk-through mode on this ceiling sensor and when should I use it?
Walk-through mode shortens the sensor's response for brief occupancy events, so someone stepping into a space for a few seconds does not leave the lights burning for a full time-out period. It is worth enabling in corridors, copy rooms, storage and restrooms where traffic is mostly pass-through. In a space where people sit still at desks, leave it off so the lights do not drop early.
8) How does the CI-300 wire up, and will it slow down a retrofit?
Wiring is through plug-style quick-connect terminals rather than screw terminals, so the sensor lands on the low-voltage run fast. It is a flush, low-profile ceiling mount, which keeps the finished look flat in occupied offices. Retrofit work still means pulling low voltage back to the power pack location at the fixture or junction box.
9) I need a sensor rated for a large open area, is this the right pick?
The CI-300 is a 360 degree ceiling PIR aimed at offices and corridors from a central mount point. If your driver is a published square-foot coverage number for a big open bay, the Leviton ODS10-ID-E is listed at 2100 square feet, which gives you a figure to design against. For large spaces the usual approach is several ceiling sensors sharing one power pack rather than stretching one unit past what it can see.
10) What is the difference between the Wattstopper CI-300 and the Leviton ODS15-IDW?
The Leviton ODS15-IDW is a PIR self-adaptive commercial grade occupancy sensor, meaning its time delay adjusts itself to room use. The Pass & Seymour Wattstopper CI-300 instead offers a walk-through mode that adjusts sensor response for brief occupancy events, and it mounts flush to the ceiling for 360 degree coverage.
11) For a corridor where I want 360 degree ceiling coverage, is a Leviton ODS10-ID a substitute for the CI-300?
They are not interchangeable in that spot. The Pass & Seymour Wattstopper CI-300 is a ceiling-mount PIR with full 360 degree coverage from a single location, suited to offices and corridors. The Leviton ODS10-ID and ODS10-ID-E are commercial grade PIR sensors rated 120/277V AC, so confirm the mounting style matches your ceiling layout before substituting.
12) Is the CI-300 a commercial-grade sensor or a residential one?
It is a commercial lighting control device, built for office, corridor and similar commercial ceiling applications, and it is part of Pass & Seymour's Wattstopper lighting controls line. It is not a standalone residential switch replacement, since it depends on a separate power pack to switch the load.
13) What exact part number do I order for the 360 degree Wattstopper ceiling sensor?
Order Pass & Seymour Wattstopper model CI-305-1, which is the 360 degree coverage configuration of the CI-300 low-profile PIR ceiling sensor. That single model is the only configuration offered, so there is no coverage pattern or finish choice to specify on the order.
