LightLEEDer-24 -32 -40 -48 Microlite® Retrofit Insert Emergency UL 924 LightLEEDer-24 -32 -40 -48 Microlite® Retrofit Insert Emergency UL 924

LightLEEDer Retrofit Insert Emergency UL 924 (Microlite compatible)

Models: LLMRI-24-EM924, LLMRI-32-EM924, LLMRI-40-EM924, LLMRI-48-EM924

A LightLEEDer Microlite® Retrofit Insert -22 -30 -38 -46 Emergency UL 924 can take your present outdated or failing lighting control system and get it up to today's  standards.  The retrofit is compatible with lighting panels manufactured by Microlite.  It provides a dependable, flexible, and energy savings controller featuring the robust Reliant40 relay. The EM Retrofit provides Emergency UL 924 operation for the panel relays and meets NFPA requirements. These panels will automatically provide a Force On, Force Off, or No Change operation for the relays based on loss of normal power. Under normal conditions, all the enhanced features of the LightLEEDer system are available with this retrofit system. Upgrades are as simple as removing the existing hardware and replacing  it with the hardware provided on a single backplate insert, reusing the existing enclosure, conduit, and wiring. It is provided with a hinged locking flush mount door.
