PAVIRO public address and voice evacuation system
About Product
The PVA-4CR12 serves as the main control hub for the PAVIRO public address and voice evacuation system. It supports eight local audio inputs that can be routed to four outputs and includes a built-in two-channel message manager for scheduled or emergency messages. Designed for flexibility and scalability, it manages up to 16 paging microphones (call stations), 492 zones, and 100 priority levels, making it suitable for large-scale installations. It also provides event logging for up to 8000 system alerts including faults and warnings. The controller comes equipped with 12 built-in zones, 18 general-purpose inputs (GPIs), and 19 general-purpose outputs (GPOs), allowing seamless integration with other systems. Capable of handling up to 2000 W of speaker load, it can be expanded further with up to 20 external routers and 40 amplifiers (each with dual 500 W capacity). The PVA-4CR12 offers a reliable and modular solution for efficient audio distribution and emergency communication in complex environments.
