Implementation of Telephone Alerting Mass Notification System
2-4.3.1 Introduction. Telephone alerting systems are independent systems that may
be used to provide mass notification to buildings and facilities. These systems are
useful for buildings in which notification to all building occupants may not be appropriate
(e.g., child development centers, hospital patient areas, brigs). They also might be
appropriate for small facilities and military family housing where mass notification is not
required by UFC 4-010-01. Use of telephone alerting systems, however, should be
considered carefully before installing in most buildings and facilities requiring mass
notification because there are many limitations in delivering notification messages by
telephone. Figure 2-4 shows the logical block diagram of a telephone alerting system.
Use of the base's switched telephone network is the preferred communications method
to minimize concerns about the system's reliability and vulnerability.
