The DRI provides a local interface between an Advanced Central Controller (ACC) and up to 2 card readers installed as entry and exit readers for a single door. This allows the DRI to receive information regarding the identity of a cardholder requesting entry or exit at a locked door and then sends the identification data to the ACC for processing. When a cardholder presents their access card at an entry or exit reader (connected to a DRI), the DRI interprets the encoded information and sends this data to the ACC. The ACC then checks the validity of the cardholder. If the appropriate permissions have been assigned, the ACC then sends a message back to the DRI allowing it to unlock the door and provide passage.
