ABSTRACT:
A message announcement system for broadcasting announcements at predetermined locations has an autonomous announcement computer at each predetermined location, wherein a plurality of event announcements and associated event identifiers are stored therein and, upon receipt of an event announcement command, the announcement computer broadcasts a particular event announcement at the location. A master computer is in communication with each announcement computer for adding, deleting or editing event announcements. This arrangement permits a modular system, whereby autonomous announcement computers, along with their associated public address systems and sign systems, may be added or removed as stations are added or removed. The system is also capable of broadcasting live announcements at each location.
