Abstract
A modular self-diagnostic assembly for controlling diagnostic, charge and transfer functions necessary to operation of fluorescent emergency lighting packs also referred to as inverters or fluorescent battery packs used particularly in emergency lighting systems such as are configured for operation with fluorescent lighting fixtures and the like. Self-test/self-diagnostic circuitry contained within a module separate from an emergency lighting pack functions as an add-on accessory to existing emergency lighting packs without need for modification of structure or circuitry of the lighting pack. The self-diagnostic module of the invention connects electrically and mechanically to the lighting pack through appropriate leads terminated by an appropriate header and further connects mechanically and electrically to a test switch module through appropriate leads terminated by an appropriate header. The resulting physical assembly is modular in concept with a first housing containing the conventional emergency lighting pack, or inverter, a second housing separate from the first housing and containing circuitry for controlling diagnostic, charging and transfer functions, the self-diagnostic …
