Abstract
A system for emergency egress advisement from a building. An egress advisement device can receive a floormap and subset of emergency egress instructions associated with routes within the building, wherein the subset of instructions are associated with a location of the egress advisement device and are used, by the device, to direct users in proximity to the location of the device to egress from that location during an emergency, locally store the floormap and subset of instructions, receive a signal indicative of an emergency, locally select, based on real-time conditions in the building relative to the location of the egress advisement device, one of the subset of instructions, which is customized for users in proximity to the location of the egress advisement device, and output the selected instructions to guide the users in proximity to the location of the egress advisement device to egress from the building.
