Which term refers to a system that disseminates alerts and instructions to occupants during emergencies?

• A. Mass Notification System
• B. Public Address System
• C. Emergency Broadcast System
• D. Fire Alarm System

Answer: (A)

Effective emergency communications rely on getting alerts and instructions to occupants through many channels, quickly and reliably. A mass notification system is built for that purpose, delivering messages across multiple media—text and voice alerts, emails, push notifications, phone calls, PA announcements, digital signage, and more—and can target messages by location or audience. This breadth ensures people receive clear, actionable guidance (evacuate, shelter-in-place, reunification) wherever they are, even if some channels are blocked or unavailable. The other systems serve narrower roles. A public address system mainly broadcasts spoken announcements inside a building and isn’t designed to reach people outside or across multiple channels. A fire alarm system focuses on detecting danger and sounding alarms to alert occupants but doesn’t distribute tailored instructions through diverse channels. An emergency broadcast system is a federal or national-level alert mechanism, not a building-specific tool for disseminating instructions to occupants.
