Abstract
A plurality of directional sounders located in a region being monitored can be synchronously and sequentially activated in various patterns to establish an audibly defined exit route from the region. Emitted audio, from a respective sounder, can be different than the audio emitted by other activated sounders to provide a path and direction for evacuation to individuals in the vicinity of the exit route.
