A PAVA system is a modern safety and communication solution that combines public address functionality with voice alarm capabilities. It allows clear dissemination of instructions, alerts, or announcements across a building or facility during normal operations or emergencies. The system consists of microphones, amplifiers, speakers, and control panels, enabling real-time communication to occupants. The importance of a PAVA system lies in its ability to enhance safety, improve emergency preparedness, and maintain effective communication, making it a critical component of modern building management and security infrastructure.
