Matrix Systems, a provider of access-control and security solutions, introduced a fault-tolerant, door-controller option for access-control connectivity. The fault-tolerance option is available with Matrix’s Frontier 5.7.5 access-control software.

When the control of access or alarm-point monitoring is threatened by a disabled common controller or network segment failure, the Matrix System Gateway (MSG) automatically maintains connections between the system’s third-tier intelligent door controllers and second-tier building controller. The MSG’s unattended fail-over capability re-routes all communication to an alternate controller and allows the system to maintain all access functions despite a key-component failure.

The new option may be installed on separate network segments for full redundancy, and allows building controllers to be shut down in a hot-swap mode for routine maintenance without affecting the access-control system. In addition, it automatically propagates data across the system from the server to the intelligent building controllers down to the door controllers. Info: www.matrixsys.com
