ABSTRACT:
An emergency lighting system powers all the luminaires of a lighting system during normal use, and switches from utility power to an emergency power source to drive some of the luminaires during a power outage. The typical on/off wall switch control for regular use carries out an automatic system test routine every time it is switched off. First, the non-emergency luminaires are extinguished, the emergency luminaires are activated for a time-limited period, and the system reverts to regular utility power and on/off control by the wall switch.
