1. A system comprising:
- a plurality of addressable speakers organized as a public address system to inject verbal messages into a region of interest;
a control unit, coupled to the addressable speakers, the control unit including circuitry, responsive to a detected alarm condition, that evaluates a plurality of non-linear escape routes from the alarm condition, a selected non-linear route is audibly communicated via at least some members of the plurality and an audio input transducer coupled to the control unit, wherein the control unit communicates a location of the selected non-linear route by automatically selecting the at least some members of the plurality of speakers one at a time along the selected non-linear route to output verbal messages from the audio input transducer.

Abstract
A public address system installed in a building or other region being monitored can communicate with a regional fire detection system. Responsive to information received from the fire detection system as to developing dangerous conditions, a control unit for the public address system can adaptively create one or more evacuation routes for a region associated with a developing condition. One or more loud speakers in the region can be used to communicate a preferred evacuation route to individuals in the region. The route can be dynamically altered as the condition varies over time.

10. A method comprising:
-
establishing a plurality of spaced apart condition detecting locations in a region being monitored; responsive to information received from at least some of the detecting locations, determining if a predetermined condition is present in the vicinity of at least one location; responsive to the presence of the predetermined condition, automatically establishing at least one time varying non-linear egress route through the region and away from the at least one location; providing an audio input transducer to inject audio into the region; and automatically selecting a plurality of speakers located along the established at least one time varying non-linear egress route one at a time to output verbal messages from the audio input transducer. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. An apparatus including a recording medium, for recording in a computer readable fashion, software to perform the following when executed by a programmable processor:
-
receiving information as to the presence of a developing dangerous condition in a region; responsive to that information, automatically establishing at least one nonlinear egress route away from the condition; arranging for emission of identifying audio indicia sequentially along the route and an audio input transducer, the audio injectable into the region; and automatically selecting a plurality of speakers located along the established at least one non-linear egress route one at a time to output verbal messages from the audio input transducer. - View Dependent Claims (20, 21, 22)

23. A system comprising:
a control unit, an audio input transducer and a plurality of speakers, the control unit including circuitry, responsive to a detected alarm condition, establishes a plurality of possible escape routes which lead away from the alarm condition where at least one of the escape routes is non-linear, wherein the control unit includes circuitry to audibly communicate the at least one route with a series of audio outputs along that route wherein the control unit communicates a location of the selected at least one route by automatically selecting at least some members of the plurality of speakers one at a time along the at least one route to output verbal messages from the audio input transducer. - View Dependent Claims (24)
