Discontinued - Dual Tech Occupancy Sensor, 24VDC, Corner Mt, 40 Khz, USA

The DT-200 sensor has had multiple versions, and the wire colors differ slightly between them. Please refer to the version of your unit (ver.2 or ver.3) to ensure accurate wiring. For DT-200 ver.3: 🔹 Red – +24VDC Input (from the power pack) 🔹 Black – Common (Return) to power pack 🔹 Blue – Control Output (to power pack or lighting load) 🔹 Green – Isolated Relay Common 🔹 Orange – Isolated Relay Normally Open (closes on occupancy) 🔹 Brown – Isolated Relay Normally Closed 🔹 Grey – Momentary Switch Input (e.g., LVSW toggle switch) For DT-200 ver.2: 🔹 Violet – +24VDC Input 🔹 Grey – Common (Return) 🔹 Yellow – Control Output 🔹 Red – Isolated Relay Common 🔹 Orange – Isolated Relay Normally Open 🔹 Brown – Isolated Relay Normally Closed 🔹 Green – Momentary Switch Input If you are unsure of your sensor version, it is usually printed on the unit label. Always confirm wire functions per your application and reference the sensor’s installation manual for detailed diagrams and safety instructions.

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.

Yes, each Wattstopper BZ series power pack can supply power for 3 DT-200 sensors.

It's not marked in percentages - it's an analog setting from minimum to maximum. Rotate the potentiometer to approximately 70% of maximum.

Yes, it mounts to a 3" mudring.
