Abstract
A system of networked lighting devices includes a group of lighting device fixture controllers connected in a communication chain. The communication chain provides for transfer of data packets between the lighting device fixture controllers and a central controller. Each fixture controller includes a first power input that receives power from a primary power source, and a priority switch that is configured to switch the fixture controller from the primary power source to a source of DC power upon detecting failure of the primary power source. The source of DC power is sufficient to power the fixture controller and enable the fixture controller to continue to pass a stream of data to other controllers in the communication chain, but it is not sufficient to power the fixture controller's associated lighting device.
