If the card technology selected for use is a PIV smart card, it is recommended that the reader have the ability
to support the PIV data structure as defined in SP 800-73 and be listed on the GSA Approved Products List
The increased deployments of smart cards as access credentials have caused the PACS industry to improve
communications between Field Control Panels and readers. In addition to the legacy one-way Wiegand
format, such communication may include bi-directional secure data transmission such as RS232, RS422 and
RS485, to name a few examples.
Internal Exit Reader Use (case example)
Works like the external “Entry” reader but updates the PACS that this card holder left the area at this
specific time. Local, state, and national fire and life safety codes strictly regulate how exit readers are
implemented. Fire codes require locking mechanisms on exit doors to be released without validation of
cards and access authorization. A PACS exit reader may be used as a tool to log an exit transaction of a
card holder as per site-specific policy. However, anyone must be able to, at any time, open an exit rated
door from the inside without use of a card or other credential. Consult with the local authority having
jurisdiction before designing a PACS with exit readers.
The local fire codes regulate the functionality and may require a push bar or approved power supply
interruption in conjunction with the reader to ensure that the doors ‘fail safe’ allowing for emergency exit
in the event of an emergency.
Portal Door Hardware
In addition to card readers, a portal (as used herein) is a PACS control point, such as a door, turnstile,
vehicle gate or any other such controlled entry location. The hardware elements are categorized into four
general areas: readers; locking hardware and barriers; door position switch and request to exit devices.
Vehicles operating in controlled areas may also be required to pass through a PACS-controlled portal.
Each component contributes to the overall security level of the controlled access portal and is often
connected to a PACS Field Controller. The operation is configured to accommodate the local requirements
at each portal.
Field controllers are hardened microprocessors that control one or several portals. Modern field controllers,
or field control panels (FCP), contain all local cardholder and authorization databases, (downloaded via a
communication line from the server), a real time clock and transaction buffer. In addition, many modern
field controllers contain operational parameters for portal hardware such as described above.
This enables the controller to function properly and make proper “Access Grant – Access Deny” decisions
in a stand-alone mode during periods when panel-server communication may be interrupted as seen in
Figure 4-5: Reader to Controller Data Flow and Figure 4-6: Generic PKI-enabled PACS Configuration.
All transactions and alarms are “time stamped” and stored in the transaction buffer until server
communication is restored, or as per site security policy, but no less than 24 hours. As communications are
re-established the transaction buffer content is sent to the server for update synchronization, archiving, and
