implementation or as a separate implementation that links a base-wide control system
for mass notification to an existing Giant Voice system. See Figures 2-3 and 2-6 for a
logical block diagram of a Giant Voice interface implementation.
Giant Voice Interface Criteria
4-188.8.131.52 Communication Network:
Use existing Giant Voice backbone communication links.
4-184.108.40.206 System-wide Features:
Has power supplies capable of accepting 110 to 240 VAC, 50 to 60 Hz.
Provides UPS or secondary (standby) power for all loads.
Provides conformance to applicable sections of NFPA 72.
Uses only COTS components.
Fault-tolerant with major component redundancy.
Easily expandable system.
Telephone Alerting System
4-2.3.1 Application. Telephone alerting systems are particularly useful for buildings
in which notification to all building occupants may not be appropriate (for example, child
development centers, hospital patient areas, and brigs). They are also useful for small
facilities and military family housing, where mass notification is desired by the base but
is not required by UFC 4-010-01. The use of telephone alerting systems should be
considered cautiously for other buildings because of the many limitations in delivering
notification messages by telephone. See Figure 2-4 for a block diagram of a telephone
Telephone Alerting System Criteria
4-220.127.116.11 Communication Network:
Provide adequate capacity for delivering messages during a worst-case scenario
within an acceptable time period.
Evaluate reliability and vulnerability of portions of the network not under direct
control of the base.
Verify compatibility with the existing phone system.
Verify that the phone system provides adequate reliability, redundancy, and
4-18.104.22.168 Central Control Unit. Provide a secure, personal-computer-based central
control unit with the following features:
Can be operated and displayed independently of the base fire alarm system.
Capable of concurrent delivery of two recorded messages: one for the threatened
facilities or buildings and one for nearby facilities or buildings.
