Hirsch DIGI*TRAC controllers are standalone access control systems that support secure ScramblePads, MATCH™ intelligent reader interfaces, high security alarm monitoring, and control relay outputs. Every controller is modular, expandable and upgradeable. Expansion boards add alarm circuits, relay outputs, communications to a PC or printer, and memory for more users, events and alarms.

For consistency and completeness, every DIGI*TRAC controller uses identical firmware so premium features and functions present no hidden costs. If later versions offer new features, firmware is replaced without replacing your controller, wiring or other system investments.
