The nIO LED LC ER does not need the UL924 listing because it never actually switches off power to the fixture at any time, and it does not wire directly to normal or emergency power. This is the same for all nIO LED devices. The device is low voltage and only connects to the LED driver dimming wires; it does not interface with the emergency power. Upon loss of normal power the nLight bus power will die, and the nIO LED LC ER will no longer have control power and becomes insignificant to the LED driver, which will cause the fixture to go to full bright.
