WattStopper DT-200 – Frequently Asked Questions

1) Does the WattStopper DT-200 occupancy sensor run on line voltage, or does it need a power pack?
The DT-200 is a low voltage sensor, operating at 24VDC. It does not switch line voltage on its own, so it has to be paired with a power pack that supplies the 24VDC and does the load switching. WattStopper's BZ-150 power pack is the one named for use with it, and that pairing is also what enables the manual-on option through a low voltage switch input.
2) Why choose a dual technology sensor like the DT-200 instead of a plain PIR occupancy sensor?
PIR-only sensors need line-of-sight motion and tend to drop occupants who sit still or work behind partitions. The DT-200 runs passive infrared alongside ultrasonic at 40kHz, so the ultrasonic side picks up minor motion the infrared misses while requiring both technologies to agree helps cut false triggering. That combination is what you want in private offices, restrooms with stalls, classrooms, and partitioned open plan. In a wide open warehouse aisle with clean sightlines and no partitions, a straight PIR sensor is usually enough.
3) Can occupants still switch the lights on manually with a DT-200 installed, instead of having them come on automatically?
Yes, if you wire it that way. The DT-200 accepts a low voltage switch input for manual-on operation when used with the BZ-150 power pack, which is how you get a vacancy-style setup where the user turns lights on and the sensor turns them off. Without that switch, the sensor runs automatic-on.
4) Can the DT-200 sensor be wall mounted, or is it ceiling only?
Both. The DT-200 supports ceiling and wall mount installation, so the same part number covers an open office ceiling grid and a corridor or small room wall position. Pick the placement that gives the ultrasonic side a clear path across the occupied area.
5) Does the DT-200 need to be calibrated after install, or does it set itself?
It self-configures. The DT-200 has auto-set functionality that selects settings for the specific space, so there is no manual calibration step at commissioning. It also carries a walk-through mode that keeps lights from staying on for a full time delay when someone only passes through a room briefly.
6) Will the DT-200 dim or shut off lights when there is enough daylight in the room?
There is a built-in light level sensor on the DT-200 for daylight harvesting, so the lighting response can be tied to ambient light rather than occupancy alone. That is useful on perimeter offices and classrooms with glazing, where holding lights on at full output during daylight hours wastes the savings the occupancy control earns.
7) How much ceiling space does the WattStopper DT-200 take up?
It is a compact square housing, 4.0 inches by 4.0 inches by 4.0 inches, weighing 0.58 lb. That small footprint and light weight matter on lay-in tile ceilings and drywall boxes where you are not adding backing or support for the sensor.
8) What is the correct WattStopper part number to order for the dual tech 24VDC sensor?
Order it as DT-200. That is the WattStopper manufacturer part number for the dual technology PIR/ultrasonic low voltage sensor, and it is a single configuration, no finish or range suffix to specify. Country of origin is China.
9) Is the DT-200 suitable for a healthcare or school lighting retrofit?
It is built for that kind of commercial work. Listed applications cover office buildings, educational facilities, healthcare environments, retail, industrial facilities, multi-tenant properties and government buildings. Since it is a 24VDC low voltage head, it fits standard commercial control architecture where multiple sensors report back to power packs rather than switching line voltage at each device, which is what facility standardization usually wants.
