How does the VA-6500 CC1 manage station PA and emergency broadcasts?

The CC1 serves as the central processing unit of the VA-6500 series — a 7″ touch-screen controller that manages zone paging, scheduled broadcasts, and background music distribution across railway or metro station zones. A dedicated PTT (Push-To-Talk) emergency microphone provides station-wide or zone-selective voice evacuation with one-touch activation, triggering an emergency mode indicated by a flashing red LED. The controller continuously monitors connected amplifier channels and speaker lines via end-of-line detection, providing real-time fault status on-screen.

What system components integrate with the CC1?

The CC1 accommodates up to 14 plug-in function cards for expanding zone count, audio inputs, or interface types. It networks with VA-6501 amplifier controllers (PA1/PA2/PA3/PA5 variants), VA-6504 broadcast consoles, VA-6505 noise detection controllers for automatic volume adjustment, and VA-6503 station management software. For tunnel applications, the VA-6511 section detector extends audio transmission over long distances.
