CTV900A
2-Door Controller
INSTALLATION MANUAL
1] PRODUCT PRESENTATION
The CTV900A is at the heart of every Centaur access control system. The Centaur Server, hardware expansion
modules, multi-purpose inputs, card readers, keypads and outputs are connected directly to the CTV900A.
Multi-controller systems are networked via the RS485 communication bus (or using the optional CAETHRA over
a TCP/IP network). Distributed database architecture allows each controller to make split-second decisions
without the need for the Centaur server. Lightning-quick, robust and remarkable stability make the CTV900A
the professional’s choice.
