dim lighting. The LMFS-601 is compatible with DALI drivers
and standard 0-10V drivers for dimming and ON/OFF control
signaling. It also provides the ability to communicate to other
DLM enabled fuxtures in the space without any additional

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
