ABSTRACT:
Signals from a plurality of detectors are evaluated to establish an ingress or an egress path or paths to and from a region. Where the detectors indicate flame or smoke concentrations, the ingress paths lead first responders to the source of the flame or smoke while egress paths lead evacuees away from the flame or smoke.
