ABSTRACT:
An emergency alerting system for alerting or warning large numbers of people of the occurrence or threat of an emergency using available communications media. Multiple facilities are monitored for the occurrence of multiple alarm conditions. On the occurrence of such a condition radio or telephone contact is made with a Local Emergency Planning Committee (LEPC) and the LEPC is notified of the site and nature of the alarm condition. Using a predetermined listing or data bank the LEPC selects a number corresponding to the site and condition and transmits such number to an automated controller for a radio transmitter. The transmitter may be part of an existing radio paging system. The automated controller, on the basis of the number dialed in by the LEPC, transmits an appropriate Code Assignment Plan (Cap Code) signal. The Cap Code signal is the electronic signature of a preprogrammed Cap Code chip within individual radio receivers positioned at the sites of intended alarm recipients. The Cap Codes are assigned and utilized to effect the notification of predetermined groups related to specific alarm conditions. Upon a receiver being actuated by receipt of its Cap Code an alarm is actuated to produce a sensory alarm signal such as sound or light. A detector is provided at the alarm site and upon detecting the sensory alarm acknowledges to the monitored facility the occurrence of the alarm.
