Questions & Answers

Is there any signal interference caused by installing switches using a metal 4” x 4” back box and plaster ring?  Will be installing in a fire rated wall, so box will also be fully covered in fireproofing putty.

Is there a lens beside the L8 for mounting the sensor at a height of twenty feet?

Asked by: Anonymous
Sorry we only have 1 lens offering for the LMFS. We do not have a solution for mounting at heights greater than 8-12 feet.

What additional devices are required for the LMFS-601 and LMFI-111 for a fixture operating on an emergency circuit (generator)? Is a wiring diagram available for that?

Asked by: Jaws001
The LMFI-111 is a power converter and is intended to be wired to a fixture’s 0–10V LED driver to control light levels. It is to only be used in conjunction with the LMFS-601 when the lighting fixture is utilizing a 0–10V LED driver and not a DALI driver. Other then those two devices the only thing you would need is the DLM Configuration App on a Android phone to do the programming. You can get a cut sheet or an installation guide from our web sight Legrand.us
