Public Alerting Systems include which of the following devices?

• A. Telephones
• B. Two-way radios
• C. Fire alarm boxes
• D. All of the above

Answer: (D)

Public alerting relies on multiple communication channels to reach people quickly during emergencies. Telephones allow direct calls and automated notifications to households and businesses. Two-way radios enable on-scene and interagency communication, helping to disseminate warnings through responders and emergency networks. Fire alarm boxes trigger local alarms and alert authorities, initiating broader warnings and responses. Because each device serves a distinct and essential role in sounding alerts and coordinating action, all of the listed devices are part of public alerting systems.
