Pass & Seymour DT-300 – Frequently Asked Questions

1) Will one DT300 sensor cover a whole conference room from the ceiling?
The DT300 mounts low profile in the ceiling and detects a full 360 degrees around itself, so it looks at the room below in every direction rather than sweeping a wedge like a wall sensor. Patented ultrasonic diffusion spreads the 40 kHz ultrasonic coverage wider for more consistent pickup across the space. Conference rooms and open ceiling spaces are among its intended applications.
2) What is the difference between a dual technology occupancy sensor like the DT300 and a plain PIR sensor?
The DT300 runs passive infrared and 40 kHz ultrasonic together. PIR needs line of sight motion and heat, which is why a person typing quietly behind a monitor or a partition can drop out of a PIR-only sensor; ultrasonic picks up small movement and reflects around obstructions. Straight PIR units, like the Leviton ODC and ODS Series commercial grade sensors, are simpler and fine in open rooms with clear sight lines. Choose dual tech where false-offs would be a complaint: private offices, restrooms, rooms with furniture or soffits breaking up the view.
3) Can the DT300 switch HVAC or feed a building automation system, not just lights?
Yes, if you order the version with the isolated relay. That relay is a separate dry set of contacts, so the occupancy signal can go to a BAS or HVAC controller independently of the lighting it is switching. Specify it at order time; it is an option on the sensor, not something added later in the field.
4) Do I need anything besides the DT300 sensor to control lights in a room?
Yes. Because it is a 24V device, the DT300 needs a low voltage power pack or an existing low voltage control system to power it and to switch the line voltage load. Budget that into the job. A single line voltage PIR sensor such as the Leviton ODS10-ID at 120/277V AC does the same job with no pack, which is often the cheaper route on a one-room retrofit; the DT300 makes more sense where several sensors and a relay panel are already in play.
5) I need an occupancy sensor that switches 120V lighting directly with no low-voltage power pack. What should I use instead of the DT300?
The DT300 is a 24V device, so it needs the low-voltage side of a lighting control system rather than switching branch circuit power on its own. For a direct line voltage install, the Leviton ODS10-ID is a PIR commercial grade occupancy sensor rated 120/277V AC, and the Leviton ODC0S-I1W is an ODC Series PIR commercial grade line voltage occupancy sensor. Both are infrared-only sensing rather than dual technology.
6) What is the difference between the Pass & Seymour DT300 and the Leviton ODS10-ID occupancy sensor?
They detect occupancy differently and sit on different sides of the control wiring. The Pass & Seymour DT300 is a dual technology sensor, pairing passive infrared with 40 kHz ultrasonic sensing, and it runs on 24V for low-voltage lighting control wiring. The Leviton ODS10-ID is a PIR commercial grade occupancy sensor rated 120/277V AC, so it is a line voltage device using infrared sensing alone. Choose the DT300 where a low-voltage control layer is already in place and where ultrasonic sensing is wanted to catch minor motion; choose the ODS10-ID where the sensor is switching line voltage directly.
7) I need a sensor that can also signal an HVAC or building automation system. Do the Leviton commercial sensors do that, or do I need the DT300?
The Pass & Seymour DT300 is available with an isolated relay specifically for integration with building automation systems or HVAC controls, and it uses a plug terminal wiring system for that connection. The Leviton ODC0S-I1W, ODS10-ID, ODS15-IDW and ODS10-ID-E are commercial grade PIR sensors for switching the lighting load. Where the sequence of operations calls for the sensor to hand an occupancy signal to a separate BAS or HVAC controller, specify the DT300 with the isolated relay.
8) How does the DT300 sensor wire up, and does it terminate with screws?
The DT300 uses a plug terminal wiring system rather than screw terminals, so the low voltage leads plug in for install and unplug for service. That matters on a retrofit ceiling: a sensor can be pulled and swapped without rewiring at the device.
9) Can I adjust how the DT300 responds, or is the behavior fixed out of the box?
Eight occupancy logic options are built into the DT300, so the sensor's response can be set to suit the room instead of accepting one fixed behavior. Occupancy indicator LEDs on the sensor show detection status, which is how you walk-test the coverage after mounting and confirm the setting is doing what you want.
10) Is the DT300 the same as the Wattstopper DT-300, and what part number do I order?
Same part. It is sold under Pass & Seymour, part of Legrand, as the Wattstopper DT300 Series, and the manufacturer part number is DT-300. There is one model on the family, so the ordering decision is the sensor itself plus whether you want the isolated relay version.
11) Is a PIR-only sensor like the Leviton ODS15-IDW an equivalent substitute for the Wattstopper DT300?
It is not a like-for-like swap. The Leviton ODS15-IDW is a PIR self-adaptive commercial grade occupancy sensor, meaning it senses infrared only and adapts its own timing behavior. The Pass & Seymour DT300 combines passive infrared with 40 kHz ultrasonic detection and offers eight occupancy logic options that the installer selects to match the space. If the space was specified for dual technology sensing, a PIR-only sensor changes what the device can detect, regardless of how its timing is tuned.
12) Which occupancy sensor covers a large open area of roughly 2000 square feet?
The Leviton ODS10-ID-E is a PIR commercial grade occupancy sensor rated for 2100 square feet at 120/277V, supplied in black. The Pass & Seymour DT300 is a low profile ceiling mount sensor with 360 degree coverage and patented ultrasonic diffusion that spreads the ultrasonic pattern over a wider area, running on 24V control wiring. The ODS10-ID-E is the choice when the area figure is what has to be met on a line voltage circuit; the DT300 is the choice when the space is served by a low-voltage control system and needs full 360 degree ceiling coverage.
13) Will an ultrasonic occupancy sensor cause problems in a room with strong air movement?
Worth thinking about before you mount it. The DT300's ultrasonic side works at 40 kHz and reads motion in the air, so it sees movement, including things you did not mean it to see. Keep it away from the direct throw of a supply diffuser and off anything that vibrates. In an open ceiling space the diffusion helps spread the pattern, but a sensor sitting a foot from a diffuser is the usual cause of lights that will not shut off.
14) Is the DT300 sensor suitable for meeting energy code lighting control on a commercial retrofit?
That is one of its stated applications, along with new construction occupancy based lighting control and commercial office lighting. The DT300 gives you automatic shutoff from ceiling level with dual technology detection, which is what most jurisdictions are looking for in an enclosed space. Check the specific control requirement your inspector is working to, since that varies by state and by space type.
15) Are the Leviton ODS10-ID and ODS10-ID-E the same sensor?
They are closely related but not identical. The Leviton ODS10-ID is a PIR commercial grade occupancy sensor rated 120/277V AC. The ODS10-ID-E is a PIR commercial grade occupancy sensor rated for 2100 square feet at 120/277V and supplied in black, so the color differs and the coverage area is stated. Confirm which one matches the sensors already installed before ordering a replacement, since the finish will be visible on the ceiling or wall.
