Abstract
An emergency lighting system capable of including both lighting and exit signage on the same circuit wherein the function of those fixtures on the circuit can be altered without resort to separate circuitry for such function alteration, loss of AC power resulting in a switching to DC
emergency mode with alteration of fixture function occurring through an interface unit in each fixture. Each interface unit comprises a simple circuit capable of producing a change in function of the associated fixture, such as level reduction, load shedding, etc., on the same circuit used for power distribution.
