Asked by: Gerard
If you mount a ceiling sensor to a wall, it will effect the way motion is detected and may not work properly.

hi i ran cat6 cable is that going to affect the installation, or it need to be cat5

Asked by: elvirus
Good morning Any Cat5 or Cat6 cable will work with the DLM installation as long as the cable is a straight thru cable. Although you can use the TIA standard 568A, TIA standard 568B is what I recommend.

I have a LMDC-100 showing E06 & E07 on the lcd display. It seems to over ride the two switches in the room. What are these codes and is there a master rest to get rid of them?

Asked by: William James
These are DLM error codes. E06: No load assigned to sensor, E07: No communication possible(Comm line is being grounded). There is a Cat5 termination issue, and a some programming needed once the Cat5 issue is resolved.

Is the LMDC-100 designed to function in low-movement settings such as conference or meeting rooms where people are always seated? Does that affect the installation height? We want to avoid lights shutting off during meetings where there isn't movement.

Asked by: JB
The LMDC-100 is an occupancy sensor. It's main function is to trigger on the load when it detects motion and keep the load on as long as it detects motion. It also will to turn off the load when it doesn't detect a motion after the time delay expires. If someone feels that it may turn off the load because people are not moving it's recommend to set the time delay to 30 minutes which is the maximum. Outside of maximizing the time delay you can put the sensor into override mode which will not allow it to use the time delay, plus the two technologies like the PIR and Ultrasonic within the sensor will no longer function and the sensor will not respond to movement or lack of movement but you will have to use a switch to turn on and off the lights because the sensor is dormant.

What is max mounting height above finish floor for the sensor LMDC-100 – U ? We intend to install LMDC-100 – U sensor to a pendant. The bottom of the mounting box is 12'-4" AFF. Is this mounting height acceptable?

Asked by: B254
The maximum mounting height for an LMDC-100 is 10 feet. It is recommended that you use an LMPC-100-5 sensor for ceiling heights from 10-40ft. https://www.legrand.us/lighting-controls-and-systems/occupancy-and-vacancy-sensors/ceiling-wall-mount-occupancy-sensors/dlm-pir-ceiling-mount-sensor-with-extended-height-lens/p/lmpc-100-5

We have 3 LMDC-100s daisy chained together and only the first one is operational. I don't see any documentation on this type of setup. Is this a valid configuration?

Asked by: Brian
Yes, the DLM system is an open topography system and it is perfectly fine to wire in that configuration. Please call Technical Support @ 800-879-8585 if you require troubleshooting assistance.
