CT-V900-A I 2-Door Controller
The CT-V900-A is at the heart of every Centaur access control system. The Centaur Server, hardware expander modules,
multi-purpose inputs, card readers, keypads and outputs are connected directly to the CT-V900-A. Multi-controller systems
are joined together via the RS-485 communication bus or TCP/IP. Distributed database architecture allows each controller
to make split-second decisions without the need of the server/computer. Lightning-quick, robust and remarkable stability
make the CT-V900-A the professional’s choice.
