Abstract
A remote emergency light system provides a base unit that is electrically coupled to one or more remote emergency light fixtures using cables. The base unit may provide power to each of the remote emergency light fixtures using the cables to activate the remote emergency light fixtures during an emergency condition. Alternatively, the base unit may provide a trickle charge to one or more remote emergency light fixtures when each of the remote emergency light fixtures includes an energy charging device. The base unit may be configured to communicate with the remote emergency light fixtures and determine when a trickle charge should be sent to a remote emergency light fixture, when a trickle charge should be stopped for a remote emergency light fixture, and/or when an energy charging device needs to be replaced. The cables can meet the requirements for Class 2 circuits as defined by the National Electric Code.
