Communication Purpose Public Address System is a speaker box connected directly to IP networking CAT5 Ethernet cable. The System is used to communicate one to many, broadcast, or to locate a person in a campus. The System can derive power from Ethernet terminator, if power over Ethernet is available or it can take local power through adaptors. The System can be grouped in multiple zones. The System has the feature that the announcer can broadcast to a single or maximum of five zones at a particular time. The Communication Purpose Public Address System ensures that single speaker access is possible by declaring that speaker as the only member in the zone.
