Abstract: Some embodiments are directed to a system that includes multiple fire sensors and equipment, and mobile devices of the users of the system. These fire sensors and equipment are configured in a network so as to allow communication with a processor. A processor in the system interrogates the status of the fire sensors and fire safety elements on a continuous basis. Upon a change in system status, the processor interprets the change and classifies according to operation state or probability of a fire or other imminent threat. The data, processing and storage provide the means by which occupants and potential occupants can better navigate a building during the occurrence of a fire.
