US Patent 11620884 Egress advisement devices to output emergency egress guidance to users

A system for providing audio and visual signaling output to egress a building. A central monitoring system can determine, based on user presence information, a floormap of the building having multiple routes and exits, receive emergency indication information indicating one or more locations within the building that may have an emergency, determine, based on the floormap and emergency indication information, egress plans that can be used by the users to exit the building, transmit, to signal generators of a first of signaling devices, first signaling instructions for the first of the signal generators to emit first signals that indicate to first users a first egress plan to exit the building, and transmit, to signal generators of a second of the signaling devices, second signaling instructions for the second of the signal generators to emit second signals that indicate to second users a second egress plan to exit the building.
