Do the Dual Technology (PIR and Ultrasonic) contain any microphones?
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.

At My office, There is a LVSW-102 that is connected to a LMDC-100. I've gone through the programming and tested out the settings, using the 5 second mode to make sure the sensor is working and it is... but the light never goes on or off automatically?
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.

how do I adjust the sensor timer? my LMDC-100 has four buttons: configuration, feature, up, down.
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.

I have the LMDC-100 occupancy sensor family installed in Revit but I cannot find how to get the coverage pattern to show up. How do I get this to show up?
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.

How do I extend the sensor timer? The sensor turns off after 20 minutes with out movement. Thanks!
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.

Sensor only controls one out of two loads
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.
