2.10.2
Operator Interface
Entry control operation shall be entirely automatic under control of the
central station and local processors except for simple operations required
for map display, alarm acknowledgment, zone and portal status change
operations, audible or visual alarm silencing and audio annunciation. The
system shall immediately annunciate changes in zone and portal status. The
alarm printer shall print a permanent record of each alarm and status
change. The map displays or graphics screens shall display the current
status of system zones and portals. The central station shall immediately
display the current status of any zone or portal upon command. While the
system is annunciating an unacknowledged zone or portal alarm, keyboard
operations at the central station, other than alarm acknowledgment, shall
not be possible. The system shall provide the capability to change zone
and portal status from alarm (after alarm acknowledgment) or access to
secure; from alarm (after alarm acknowledgment) or secure to access, or
from access to secure by simple control operations. If the operator
attempts to change zone status to secure while there is an alarm output for
that zone or portal, the system shall immediately annunciate an alarm for
that zone or portal.
2.10.3
Entry Control Functions
2.10.3.1
Multiple Security Levels
The system shall have multiple security levels. Each of the security
levels shall be delineated by facility barriers. Access to each security
level shall be through portals in the facility barriers using designated
entry control procedures. The system shall provide at least 8 security
levels. Any attempt to access an area beyond an individual's security
level shall initiate an access denial alarm.
2.10.3.2
Two person rule
The system shall provide a 2 person rule feature. When a portal is
designated as a 2 person rule portal, it shall not allow passage unless 2
valid identifiers are presented in the proper sequence. The scheme shall
be designed so that only the first 2 valid identifiers and the last 2 valid
identifiers pass together.
2.10.3.3
Anti-Passback
**************************************************************************
NOTE: The designer will show on the drawings or in
a table all portals that will use anti-passback
procedures and equipment. The designer will also
show on the drawings the location of release
switches for electromagnetic locks or electric
strikes at portals not incorporating anti-passback
procedures.
**************************************************************************
Portals as shown shall incorporate anti-passback functions. Anti-passback
functions and identifier tracking shall be system-wide for portals
incorporating anti-passback. Once an authorized, enrolled individual has
passed through a portal using entry control procedures, the system shall
not allow use of the same identifier to pass through any portal at the same
security level until the individual has egressed through a portal at this
same security level using entry control procedures. Any attempt to violate
