DLM Dual Tech Ceiling Mount Sensor V4, White, USA

While the LMDC-100 and similar occupancy sensors are designed for long-term, low-maintenance operation, some periodic upkeep may be beneficial depending on the environment and usage conditions: 🔹 Dust and Debris: In dusty or high-traffic areas, cleaning the sensor lens or cover occasionally can help maintain optimal detection performance. 🔹 Environmental Changes: Updates to room layout—such as added furniture, partitions, or new heat sources—can impact the sensor’s coverage and may require adjustment. 🔹 False Triggers or Missed Detection: If the sensor begins to misbehave, recalibration or repositioning might be necessary. Although routine maintenance is not typically required, periodic checks in demanding environments can help ensure reliable operation. For detailed product information, including installation, configuration, and maintenance guidelines, please refer to the Installation Instructions available under the Resources section of the product page on the Legrand website.

No, Dual Technology sensors do not contain microphones or any audio recording capabilities. These sensors use two methods to detect motion: 🔹 Passive Infrared (PIR): This technology senses changes in heat, like when a person moves through a space. 🔹 Ultrasonic: This part sends out high-frequency sound waves (not audible to humans) and listens for changes in how those waves bounce back. It helps detect even slight motion, but again, there’s no audio recording involved. These technologies work together to improve accuracy, but neither one records or listens to actual sound.

The LMSW-102 switch and LMDC-100 ceiling sensor both communicate with a room controller, typically installed in the ceiling of the same room or a nearby area. Identifying the specific model of that room controller is important, as it determines how the devices operate together. If the sensor appears to function correctly but the lights are not responding automatically, it may indicate that the system hasn’t been properly commissioned, or that settings need to be adjusted via the LMCT-100-2 handheld configuration tool. For the most accurate troubleshooting and configuration assistance, we recommend reaching out to Wattstopper Technical Support. We’ll help tailor a solution based on the specific devices and layout in your space.

To adjust the sensor timer on your LMDC-100 V3: 1. Remove the sensor’s cover to access the buttons and LCD screen. 2. Press the Feature button once to display the Time Delay setting. 3. Use the Up or Down button to adjust the delay to your desired duration. 4. Replace the cover once the adjustment is complete.

Wattstopper previously provided Revit files; however, they no longer create or maintain these files. As a result, I’m unable to provide specific guidance on displaying the coverage pattern within Revit. I recommend checking with your Revit support resources or exploring Revit forums, as they may offer workarounds or user-generated content that could assist you with this functionality.

The maximum time the sensor time delay can be set to is 30 minutes. Please see the attached programming information from the installation manual. Programming can be done on the sensor, or with the LMCT-100-2 programming tool.

It sounds like the sensor was not bound to the second load correctly. Please follow the instructions for load binding in the installation manual to bind the second load to the sensor. If assistance is needed, please contact Wattstopper Technical Support @ 800-879-8585.
