A PAVA system is a Public Address and Voice Alarm system, used for both routine announcements and critical emergency alerts in large buildings or public spaces. These systems use a network of microphones, amplifiers, and loudspeakers to deliver clear audio, with a key function being to provide clear, actionable voice instructions during emergencies like fires to help occupants evacuate safely. PAVA systems are often mandatory in high-risk or high-occupancy environments such as airports, hospitals, and shopping centers.
