Emergency evacuation route determining system i.e. server, for guiding firefighter in building during evacuation of person, has switching interface activated by user to switch determination module from operating mode to other operating mode

摘要

The device (6) has a determination module (3) for determining a safe evacuation route between each light (2) and a safety zone relative to a length of passages in an operating mode, and determining an orientation route to an alert sensor (5) in another operating mode. The module generates a display command such that each light indicates a passage belonging to one of routes. A switching interface (33) is activated by a user to switch the module from the former mode to the latter mode. A control circuit powers LEDs with distinct supply voltages relative to the respective mode.
