Abstract
A conversion kit or assembly for standard exit sign constructions is provided which allows quick and easy changeover of the sign (which is normally illuminated only by standard 120 volt building current) to a design wherein a secondary source of illumination and electrical power is provided for emergency use. The conversion kit includes a replacement support housing having a battery and printed circuit board therein, along with secondary bulbs designed for quick attachment within the sign lens unit, and wiring means for connecting the primary and secondary illuminators to respective power sources. The secondary bulbs are wired to light only upon a failure of normal power, so as to ensure operation of the exit sign. A test switch is also provided for periodically testing the secondary illumination system.
