Dual Tech Occupancy Sensor 100 -347 VAC, center mount 360 USA

If a DT-355 sensor fails, the lights remain in their current state.

Questions to Consider: 1. Circuit Setup: -Are they wired in parallel from the same electrical circuit? 2. Settings: -Have any settings on either device been modified from their factory defaults? 3. Independent Functionality: -Have you tested each device individually to ensure they function correctly on their own? Troubleshooting Steps: 1. Verify Circuit Connection: -Ensure both the DT-355 and PW-301 are connected to the same circuit and wired correctly in parallel if they are controlling the same fixtures. 2. Check Settings: -Reset both devices to their factory settings and see if the issue persists. Sometimes, setting changes can lead to unexpected behavior. 3. Test Separately: -Disconnect one device and test the other in isolation. Repeat for the second device. This can help identify if one of the devices is causing the problem. 4. Contact Technical Support: -If the above steps do not resolve the issue, it might be best to reach out to Technical Support. Provide us with detailed information about your setup and the steps you've already taken. We can offer more customized solutions based on your specific situation. By systematically addressing each of these points, you should be able to identify and resolve the issue with your line voltage sensors.

No, the DT-355 is not suitable for damp locations. Please see the cutsheet for the HB30xW series sensors @ https://www.legrand.us/search/?text=HB3x0W. These are the sensors we do offer for wet locations.

Please see the image attached.

The DT-355 is simply a line voltage, dual-technology occupancy sensor. You would need to contact Lutron to review their system requirements.

For Low Voltage installation, I'd recommend the DT-305 sensors, LVSW-101 switch, and BZ-150 power pack. This would require low voltage wiring from the sensor locations and switch location to the power pack. If you wanted a line voltage solution, take a look at the DT-355 sensors, but keep in mind that they won't interface with a low voltage switch.

the actual PIR and/or Ultrasonic sensors within the DT-355 are not field replaceable. If the sensor(s) have been damaged, the entire DT-355 would have to be replaced.

Hi Derek, Multiple sensors can be wired in parallel. Please refer to the installation instructions for wiring diagram.
