Questions & Answers
Light switche works the dual motion lights up and looks like it works but the lights do not turn off at all when no one is in the room for hrs
The DT-205 is a low-voltage dual technology occupancy sensor that relies on both passive infrared (PIR) and ultrasonic detection. It operates in conjunction with a Wattstopper power pack, which supplies 24VDC to the sensor. If the lights are not turning off, there are several key factors to check:
1. Ultrasonic Sensitivity Setting:
The ultrasonic sensitivity trimpot may be set too high. This can result in the sensor detecting minor vibrations or noise (like HVAC airflow) and falsely interpreting them as occupancy. Reducing this sensitivity, ideally setting it to around 50%, is recommended for most spaces.
2. Test Mode:
It’s useful to place the sensor into Test Mode, which shortens the time delay to 5 seconds, allowing quick validation of sensor functionality. If the lights still do not turn off, this confirms an issue with wiring, placement, or sensor configuration.
3. Power Pack Verification:
If the power pack’s relay is stuck or damaged, the lights could remain on regardless of sensor input. Temporarily disconnect the blue wire from the power pack. If the lights go off, the sensor is likely at fault. If the lights stay on, the power pack relay may need replacement.
4. Environmental Interference:
Review the sensor’s placement. If it is too close to vents, fans, or machinery, ultrasonic reflections could falsely trigger occupancy. Relocating the sensor may help.
For step-by-step guidance tailored to your specific installation, Wattstopper Technical Support is available and can walk you through further troubleshooting based on your exact site conditions.

Can 2 DT-200 be in parallel off the same BZ-50 power pack ?
Yes, each Wattstopper BZ series power pack can supply power for 3 DT-200
sensors.

How do you know that sensitivity is set to 70% on the adjuster. I don’t see any arrows or indicators on the dial
It's not marked in percentages - it's an analog setting from minimum to maximum.
Rotate the potentiometer to approximately 70% of maximum.

Im was wondering how to increase the time before the lights turn off. I am a custodian at an elementary school and I have complaints from teachers when there in their classrooms without students.
The sensor has a maximum time delay of 30 minutes and is set by adjusting the "dip switches" 1, 2, and 3(shown on page 5) on the instruction sheet. The link to it is provided below:
