OPEN controller is the ideal access control solution for small and medium installations. OPEN provides a sophisticated entry-level security solution, including for doors, parking and interlock. Optional TCP/IP on board is available.


OPEN is a 2-reader/1-door or a 2-reader/2-door controller fitting a wide range of installations up to 8,000 cardholders (expandable to 44,000 cardholders with 512K of memory – OPEN 512K). Depending on its configuration, it can store up to 8,000 events (expandable to 47,000 events with 512K memory). It comes with 4 inputs and 3 relays.

Communication with the host is ensured via the RS232 or RS485 communication bus, or the built in TCP/IP interface (option). In case of on-board TCP/IP, the controller acts as a concentrator, this allows RS485 connection to other DDS controllers, without additional costs.

The elaborate access control capabilities include daily and weekly programs, holydays / special days, security levels, RTX, escort, anti-passback, etc.

The alarm management functions supervise local and global reflexes, unsuccessful attempts, door alarm, duress alarm, etc.

OPEN is easy to use. The system can be installed in a matter of minutes. Programming is simple. The Flash memory allows easy firmware upgrade. The use of removable connectors will greatly ease system updates.

The intelligent controller supports almost all reader's technologies.

This robust controller is capable of withstanding the most adverse environments. OPEN takes independent decisions at the local level, such as door opening or outputs / reflexes triggering, without any computer intervention.
