Which system provides emergency voice alarm communication?

• A. Emergency Voice Alarm Communication System
• B. Public Address System
• C. Fire Suppression System
• D. Access Control System

Answer: (A)

In emergencies, delivering clear, authoritative voice messages to occupants is essential, and the system designed for this purpose is the emergency voice alarm communication system. It is built to provide reliable, prioritized voice messages synchronized with the fire alarm, often with supervised circuits and backup power to ensure messages reach people even during power or communication failures. The public address system can handle general announcements but isn’t guaranteed to operate under emergency conditions or integrate with fire signaling, while fire suppression and access control systems handle extinguishing and door access, not occupant-wide emergency messaging.
