LightLEEDer Emergency UL924 Lighting Control

Models: LLXX-EM

The LightLEEDer Emergency UL 924 bypass relay control panel will force relay's ON during a normal power outage.  This panel has all the same features and functions as a standard LightLEEDer lighting controller, allowing normal control of relays with emergency bypass during a normal power failure event. Relays can be all EM or a combination of normal and EM.  Each output has a jumper for selecting Force On, Force Off or No change, this allows for emergency on, load shedding off, or no control selection for each relay.  Provided With Phase monitoring module and high voltage dividers. This LightLEEDer Emergency lighting panel is easy to install, no external devices or complicated wiring configurations needed, reducing material and installation costs.
