Implementation of Giant Voice System. The Giant Voice system is typically
installed as a wide-area system to provide siren signal, pre-recorded, and live voice
messages. It is most useful for providing mass notification for personnel in outdoor
areas, expeditionary structures, and temporary buildings. Giant Voice is not usually
suitable for most permanent inhabited buildings, and must not be used in lieu of an
individual building mass notification system. If an optional base-wide control system for
mass notification is installed (see paragraph 2-5), it should be interfaced to a new or
existing Giant Voice system. Figure 2-3 shows the logical block diagram for a Giant
Voice system.
