Abstract
A system for centrally managing and executing emergency egress guidance. A first computing device can receive an indication of an emergency and user presence information in a building, retrieve, from a local data store, generated egress instructions for the building, select, for each of a plurality of egress advisement devices and based on the emergency indication, user presence information, and location of each egress advisement device, one of the egress instructions that is customized for each egress advisement device, and transmit, to each egress advisement device, the selected instructions to be outputted to guide users to exit the building. Each egress advisement device can determine that communications are terminated between the egress advisement devices and the computing device, obtain the emergency indication and user presence information, and retrieve, from the local data store, a second of the egress instructions associated with the location of the device.
