ACCESS CONTROL PANEL CODE
Typically, they only receive those that their readers are authorized to process.Īdditionally, decisions based on schedules (Day of Week, Time of Day, etc.) are also downloaded on an “as needed” basis to each Access Control Panel.īut what happens if a card is presented to a card reader that has not been programmed into the system? The Access Control Panel may be programmed to reject the card if the card does not include the facility code of the facility in question.īut sometimes large corporations use a common facility code across several facilities, so the card may be valid for the facility, but not programmed into the Access Control Panel. Not all panels receive the entire user database. It is the Primary Host Server that decides what access programming to send to each panel and which authorized users to place in the panel's authorized user database. This panel may have 16 readers connected to it (one in/one out for each turnstile) and have a daily throughput of 12,000 authorized users.
Another panel may serve 8 turnstiles from the employee lot of a large factory.
It may have 10 readers connected to it and a total of 400 authorized users for those readers. One panel may serve 10 doors within a department. Thomas Norman, in Electronic Access Control, 2012 Decision ProcessesĪlthough basic system decisions (grant/deny access) are made by the Access Control Panels, it is the Primary Host Server that programs these and distributes the programming appropriately to all the Access Control Panels.
