Description
This is an expansion of application (3). The DK-2891 is expandable to a multi-station system in
Split-decoded operation. It is compatible with the auxiliary readers AR-2802 and the auxiliary
reader-keypads AR-2806, AR-2807 & AR-2809. Total 3 auxiliary readers or reader-keypads can
be connected in parallel with the Data I/O Bus. They provide the same functions like the master
keypad in using cards and user codes. The DK-2891 that is the server of the system manages
the data with its Data I/O Bus among the associated devices. This approach gives high security
in sabotage prevention and user convenience.
