Paging Systems are a public address or loudspeaker wireless communication system specially designed for a one-way communication to a large group of people to make announcements and notify or summon people. In large buildings, paging systems commonly are divided into a number of zones, or coverage areas.
A paging system allows for one-way communication to a large audience. Regardless of the broadcast source, a one-way paging system lets the speaker provide clear, amplified instructions throughout a facility. The paging employee speaks a message into a telephone and that message is then broadcast through a network of speakers. Messages can also be recorded and broadcast at a later time.
