Abstract: An evacuation priority system for use in installations having a plurality of separate areas therein includes a plurality of detecting means, such as fire or smoke detectors, each for detecting an appropriate alarm condition in the respective area. Inputs from each area responsive to the alarm condition are received by a central processing unit (CPU), and a priority is computed between the inputs on a predetermined basis dependent upon the relative emergency between the alarm conditions detected. An evacuation route is then selectively fed into an indicating means within each area, on a priority basis or simultaneously, to identify appropriate evacuation routes from each area. Information received by the CPU is forwarded to the appropriate emergency agency, for determining the appropriate equipment and manpower to be used. In addition, information received and processed by the CPU is stored to document the emergency to help reconstruct and avoid similar occurrences.
