Dual Tech Occupancy Sensor 24V DC, center mount 360°

Thank you for your question. Based on the behavior you're describing, it would be best to contact our Technical Support team directly so we can assist in diagnosing the issue more accurately. To start the troubleshooting process, we’d first want to confirm a few details: 🔹 Has the sensor ever operated as expected? 🔹 What power pack is being used with the DT-300 sensor? 🔹 How is the sensor wired to the power pack? 🔹 What are the current DIP switch settings on the sensor? 🔹 If your power pack has a mode selector, what mode is it set to? Unfortunately, due to the nature of sensor diagnostics, it’s difficult to effectively troubleshoot through written communication alone. For the most efficient assistance, please give our Technical Support team a call—we’d be happy to walk you through the steps to get everything working correctly.

There are several factors that could cause the DT-300 to stop functioning, even if the LEDs are blinking and no breakers have tripped. It could be related to the sensor itself, the power pack it's connected to, wiring issues, or even the age of the device. To properly isolate the cause, we recommend giving us a call so we can walk you through a few troubleshooting steps. A voltage meter is helpful during this process, as we may need to confirm power at various points. We're happy to assist you and help you determine whether the sensor needs to be replaced.

Yes, the DT-300 occupancy sensor is capable of controlling two power packs simultaneously. This allows it to manage multiple loads from separate sources based on occupancy detection. For assistance with wiring configuration and to ensure proper functionality for your specific application, we recommend contacting Wattstopper Technical Support. They can provide a detailed solution tailored to your installation requirements.

The re-trigger function on the DT-300 is not a setting that needs to be enabled; it is a built-in behavior of the sensor. After the lights turn off due to the time delay, the DT-300 will re-activate the load if motion is detected within a 30-second window. This re-trigger period is automatic and does not require additional configuration.

To bypass the DT-300 sensor and rely solely on the wall switch for controlling the lights, remove the cover and adjust the Ultrasonic Sensitivity trimpot to its minimum setting. This will place the sensor into Service Mode, effectively disabling its occupancy detection functionality. The sensor will indicate it is in Service Mode by displaying a solid red LED. Important Note: If the Ultrasonic Sensitivity trimpot rotates continuously (360 degrees) without stopping, this indicates that the trimpot has been physically damaged due to over-torquing. In this case, the sensor would no longer function correctly and would require replacement.

For low-voltage 24V sensor connections, standard low-voltage cable practices apply. Thermostat wire is commonly used and suitable for these applications. To ensure proper performance, you should select the wire gauge based on the total current draw of the sensor and the length of the wire run. Referring to the wire gauge selection chart, consider both the current draw of the DT-300 and the total wire run distance (including both the outgoing and return paths). This helps to limit voltage loss to no more than 10%. For example, if your current draw and wire run are similar to the provided example, a minimum of #22 AWG wire may suffice. However, longer runs or higher current draws might require thicker gauges, such as #20 or #18 AWG.

Hello, we may need to troubleshoot to determine if there indeed is a component issue. Simply start with disconnecting the blue control output wire on the back of the sensor - it is low voltage. If the lights turn off when this is done the power pack is fine - possible sensor issue. If lights remain ON when the wire is removed - power pack needs to be replaced.

The maximum delay time on a DT-300 sensor is 30 minutes.
