IMPLEMENTATION OF BASE-WIDE CONTROL SYSTEMS FOR MASS
NOTIFICATION. Implementing a base-wide mass notification system is not required but
offers the advantages of central monitoring, control, and message delivery. An
implementation plan should be the first step in preparing for a base-wide system. The
implementation plan provides a roadmap to the final planned system, and determines
base-specific criteria for evaluating and selecting contractors, manufacturers, and
products. Paragraph 1-6.3 provides more information on developing an implementation
plan. Figure 2-5 shows the logical block diagram for the implementation of a base-wide
control system. Figure 2-6 shows the logical block diagram when Giant Voice is
interfaced to a base-wide control system for mass notification.
