Questions & Answers
What does it mean if the red led is on.
A solid red LED on an LMSW (Digital Lighting Management Switch) typically indicates one of the following issues:
Faulty Hardware or Connection Issues
🔹 A damaged LMSW switch, defective DLM cable, or a faulty room controller can cause the solid red LED.
🔹 Testing with another known working switch can help diagnose the issue.
Troubleshooting Steps:
✅ Check the DLM Network Connections: Ensure all RJ45 cables are securely connected.
✅ Inspect the Room Controller: Make sure the LMRC is powered and functioning.
✅ Power Cycle the System: Turn Off and back On the breaker to recycle the room.
✅ Use a Different Port or Replace the Cable: If available, try another port or swap the cable to rule out a bad connection.
✅ Factory Reset the Switch: If needed, hold the configuration button for about 10 seconds to reset settings.
✅ Swap with a Known Working LMSW: If another switch works fine, the original may be defective.
Call Wattstopper Technical Support: A technician can custom tailor a solution based on the specific issue being reported.

can this dim 0-10 volt drivers or is it just adjusting sensor to preset hi and low trim levels. I need to be able to dim from 100 down to about 5% if needed.
Hello,
The FS-205 occupancy sensors turn lighting ON and OFF based on occupancy and ambient light levels. It does not have continues dimming

My lights are not automatically turning off. Does this mean the sensor has gone bad or would a bad sensor not allow the lights to turn on at all
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.
Please call us if further assistance is needed, 1-800-879-8585 opt 3

can I wire these together so that when one area comes on they all come on. I have 3 currently servicing a barber shop. when 1 area comes on I want them all to come on, Is this possible with the DT 305? If so how?
Hello,
It sounds like we have three separate power packs, we can use one power packs red/blue/black and the other two packs we will cap the red 24v off and in parallel connect the blues and blacks.

Are these occupancy sensors exterior rated? If not, what occupancy sensors are?
The Wattstopper CI-305 is not exterior rated. For outdoor applications, I recommend looking into the FSP line of sensors, which are designed for outdoor use.
