individual. A Type II error grants access to an unauthorized individual.
Subsystem Type I and Type II error rates shall be both less than [0.1]
[_____] percent. At the error rates, subsystem access throughput rate
shall be minimum of [12] [_____] individuals per minute through one card
reader and keypad access control device.
2.4.15.2
Access Control Subsystem Central Processing
Provide serial management and control of subsystem. Provide a
microprocessor control device designed to monitor and control units and up
to [32] [_____] card reader and keypad access control devices. Central
processor shall interrogate and receive responses from each control unit
within 100 milliseconds. Failure to respond to an interrogation shall
cause an alarm. Provide a printer with a minimum print rate of 30
characters per second to produce hard copy of subsystem events. Provide
the central processor with an EIA ANSI/EIA/TIA-232-F interface port to
communicate with the printer. Provide an operator interface to control
system operating functions. Provide the central processor with a
facility-tailorable data base for a minimum of [1000] [_____] card holders
with by-name alphanumeric printout, and for automated [subsystem] [IDS]
monitoring, management, and control functions. Provide enrollment
equipment to process access control cards and enroll personnel into and
disenroll personnel from the subsystem data base. Enrollment equipment
shall not be accessible to IDS operations personnel. Provide a minimum of
[150 percent of the number of card holders specified above] [_____] access
control cards with the enrollment equipment. Provide system configuration
controls and electronic diagnostic aids for subsystem setup and
troubleshooting with the central processor. Components shall not be
accessible to operations personnel. Central processor components shall be
tamper alarmed.
2.4.15.3
Access Control Subsystem Control Unit
Unit shall be microprocessor controlled with onboard data communication
capability for full duplex communication to and from the subsystem central
processor over either four wire continuous dc lines or voice grade
telephone lines. Response to a central processor interrogation shall be
within 100 milliseconds. In the event of a communication loss, control
unit shall automatically convert to local control of the associated card
reader and keypad access control devices and shall automatically revert to
central control upon restoration of communications. Control unit shall be
capable of control of up to four card reader and keypad access control
devices, of controlling access based upon a minimum of [16] [_____] time
zones, of monitoring associated portal status and associated IDS sensors,
and of interfacing with the IDS for the purpose of communicating sensor
alarms. Control unit shall provide associated electronic strike power and
control and an electronic strike energize time adjustable from one to 30
seconds. The control unit shall contain critical circuitry for operation
of the associated card reader and keypad access control devices and shall
be located within the IDS-protected perimeter. Enclose control units in a
tamper-alarmed enclosure. Control unit shall report as an alarm, by
location, forced portal openings, portals held open over a predetermined
period of time, reader tamper, illegal card use, tamper, power failure, and
access or exit request denials. Control unit shall support paired card
reader and keypad access control devices on a single portal for
anti-passback functions. Provide electronic diagnostic aids within the
control unit to aid in subsystem setup, maintenance, and troubleshooting.
