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

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.

Thank you for your question. The DT-300 is not rated for installation in a wet area.

Hello David, I have checked our inventory, and discontinued list. The DT-305 is not an obsolete item, and is available

Wattstopper does not sell a replacement for the faceplate, but the Technical Support Department may be able to help. Please contact Technical Support at 800-879-8585 and one of our technicians will be happy to assist.
