When more than 1,000 users must be enrolled in a single iGuard network, a Super Master memory module is also used. The Super Master serves as the network Master Unit and iGuard LM520 Series readers are used at each station where door control or Time & Attendance recording is required. As in a simple iGuard network, continuous synchronization between the iGuards and the Super Master assures the Super Master database contains a copy of every Access Log transaction recorded at each door / station.
Super Master modules are available in sizes to accommodate 5,000, 10,000 or 20,000 users. Larger capacity modules are available on a Build-to-Order basis.
