Abstract
An emergency lighting system including a plurality of lights including a first group of lights and a second group of lights, a switching circuit, and a controller. The switching circuit includes a relay. The relay has a first position, in which power from the driver is provided to the first group of lights and the second group of lights; and a second position, in which power from the auxiliary power supply is provided to the second group of lights. The controller is configured to output a signal to the emergency control input when an input voltage is below a threshold. Wherein, the switching circuit places the relay in the second position upon receiving the signal at the emergency control input.
