Abstract
A distributed emergency building lighting system senses the presence or absence of AC power at the input of a switch controlling lighting in a designated area or an input stimulus such as an alarm to provide low-level marking for visual delineation of the path of egress or lighting of a predetermined designated area by illuminating an EL panel in accordance with code requirements. Self-diagnostic testing verifies operational conditions of the battery and illumination circuit to ensure code compliance.
