Access Control System
October 29, 2002
From American Auto-Matrix (AAM), the KeyMaster access control system includes Microsoft Windows-based software packages along with appropriate controllers and readers. They target both high- and low-end access control applications. The Key Master Pro system provides integration to AAM’s HVAC control products, CCTV and time and attendance systems. Software packages use RS-232, RS-485 or Wiegand standards to interface with the hardware.
