Control of 2 physical doors (2 input readers) 256 access levels Add 3 CAA470ATRs expansion modules to manage 6 additional doors Buffer memory for 2048 events 2 outputs with relays Centaur is compatible with Windows 10 The CTV900ATR is the core of the Centaur access control system and allows the management of up to 2048 doors. The server, readers, expansion modules as well as all inputs and outputs are directly connected to the CTV900A. Systems with multiple controllers are connected into one by the RS-485 communication bus. The integrated software architecture of the database allows each controller to make decisions in a fraction of a second. So professionals choose the CTV900A : fast, robust and remarkably stable. Control of 2 physical doors (2 input readers). Control of 1 physical door (entrance/exit). Up to 6 additional doors can be added to the CTV900A with 3 additional CAA470A expansion modules. Integrated database with a capacity of 10920 chips : badges, digital fingerprints, codes. 256 timetables. 256 access levels. Buffer memory for 2048 events. 16 integrated inputs. 2 integrated outputs "locking" of 12 Vdc or 24 Vdc, selectable by sweater. 2 outputs with relays (N/O - N/C). Fully integrated database architecture (access decisions are taken locally or globally by software). E-Bus technology. Switched mode power supply of 2.5 A. Supports Wiegand, ABA Track (magnetic strip) and BCD (keyboard) communication formats. Easy maintenance and installation due to removable connection terminals.
