is met, a relay is operated to energize or open an electric lock and close
the electric lock after the proper elapsed time.  The controller also may
supply conditioned power to the reader.  Some system configurations utilize
controller electronics within the reader assembly.  Caution is advised when
using this type of system.  Most system requirements indicate a need to have
all decision-making electronics within the protected perimeter to avoid any
compromise that may result in defeat of the system.
5.2.5  Central Control Unit.  The central control unit refers to the
electronic devices which process information regarding the automated access
control.  Enrollment Console.  The enrollment console is the device used to
initiate the authorization status of an encoded badge.  This device can be a
keyboard, badge reader, or video display terminal.  Information entry
regarding badge authorization can include badge number, employee number,
name, address, telephone, motor vehicle registration, status, issue date,
return date, authorization center, and portal restrictions by time zones,
entry/exit status, and trace.  Also included may be a commentary section
which is often utilized for emergency call lists and other safety-related
information.  The enrollment display usually consists of a
fill-in-the-blanks or input directions that permit a large volume of
authorizations to be processed as a clerical task.  Changes of high
authorization levels are generally password or software protected to prevent
unauthorized use of the system.  It is recommended to have passive software
protection on all system functions.  Central Processor.  Decisions based upon information files entered
at the enrollment console are conducted by a central processing unit in
collaboration with memory and operating systems.  This device communicates
with remote controllers and checks the encoded information input against the
existing files; it then approves access based upon the filed authorizations.
The central processor also creates a historical file of attempted accesses
and the manipulations of the existing files.  This history may be recorded
either electronically in computer storage media or printed on paper for
later permanent review.  The information files in computer storage media are
available for statistical and other manipulative processing and reporting in
a variety of report formats.  Power loss will often affect the system
memory; backup power systems should be considered to maintain integrity.  Printer.  The printer is an output device which provides a hard
copy record of activities reported by the central processor.  Considerations
of printers with systems include sufficient speed and appropriate buffer to
avoid information omissions from overload by the much faster system
electronics.  The print speed is often controlled by the quality of type
fonts, cost, and data transmission technique.  Security systems do not
generally require letter quality printing; therefore, faster printing can be
accomplished with fewer cost constraints.  Care and security of printer
output must be seriously considered, particularly if the only historical
reporting is based upon real time activity printing.  This type of record
will realize a great importance in the event of security breaches or other
need to develop an
