Title
(EN) Modular uninterruptible lighting system
Abstract
(EN)

A modular fail-safe uninterruptible lighting system in which lights are identified singly and/or in clusters to form separately controllable entities. Each entity is provided with a modular receiver that is individually controllable to any of six selected states; and one or more modular switched logic controllers is provided to produce signals individually representing the six states. These signals are conducted from the switched logic controllers to the receivers at relatively low control voltages so as to cause the entities to function according to selected states when an outage occurs on the normal lighting system power source.
