Access Control

October 1, 2008

Matrix Systems (Dayton, OH) offers Frontier® 5.7.5 access control software with a fault-tolerant door controller option with triple-tier data distribution redundancy. When the control of access or alarm point monitoring is threatened by a disabled common controller or network segment failure, the Matrix System Gateway, an Ethernet-to-485 converter/ switch, automatically maintains connection between the system's third-tier intelligent door controllers and second-tier building controller. The fail-over capability re-routes all communication to an alternate controller and allows the system to maintain all higher-level access functions in the event of a key component failure.

The fault-tolerance option features include installation on separate network segments for full redundancy, the ability for building controllers to be shut down in a hot-swap mode for maintenance, and automatic propagation of data across the system from the server to the building controllers, to the door controllers.
