Easy to set up and use, the Citadel access control system is remarkably powerful, efficient
and extremely cost effective. This modern, affordable access control system is perfect for typically smaller, simpler jobs. Designed with network capability, Citadel has the flexibility to control one
or several buildings using a direct, dialup or network connection. Users set their access control requirements at a host computer that communicates with controllers. These specialized computing devices make decisions to allow or deny access. Transaction records are then stored in the controllers' memory and are communicated back to the host computer.

Powerful, Modern Access Control

Through distributed processing, both access control decisions and transaction recording are carried out by the
individual controllers. Citadel will continue to operate fully
during a computer failure, and with an optional 12V 4Ah backup battery, will operate during a power failure. When
power is restored, Citadel's controllers are fully functional, remembering the user's access requirements and recorded
transactions.

This easy and affordable Citadel system supports over 4,000 cardholders, and moves beyond access control to provide
over 190 input monitoring points per site. It also supports multiple dial-up or networking sites with spontaneous and
instantaneous reporting of alarms to its host computer.
