Which statement accurately describes voice evacuation systems?

• A. They are visual-only devices
• B. They are used to test the alarm system
• C. They replace fire alarm control panels
• D. They can be used to give specific information or instructions over the alarm system using a built-in microphone

Answer: (D)

Voice evacuation systems are built to deliver spoken instructions to occupants during emergencies, not just make sounds. They work with the building’s fire alarm control system and use loudspeakers to broadcast clear messages. The built-in microphone lets trained personnel issue live instructions or trigger pre-recorded messages to specific areas, providing precise directions like which exit to use or when to shelter in place. That capability—giving specific information or instructions over the alarm system via a microphone—is why this statement is the best choice. These systems are not visual-only, they aren’t merely for testing the alarm, and they don’t replace the fire alarm control panels; they augment them to communicate effectively during evacuations.
