GLOSSARY
TERM
EXPLANATION
Access
The method by which the reconfiguration program is entered, that is, by pressing
function keys whose effects are displayed on a menu on your terminal screen.
Access Control
The subsystem which allows locations to be protected, by prohibiting all entry into
them except by authorized personnel carrying access cards.
Access Inhibited
A condition which can be applied to a security zone. While the condition applies, no
access is permitted into the zone
.
Access Level
A record containing one or more zones into which access is permitted, with the times
at which they may be entered. Access levels are then assigned to holder records,
thus permitting different groups of personnel to be given access to different zones at
different times
Accountability
The ability of the access control subsystem to keep track of access card holders as
they enter and leave security zones. Three levels of accountability are available:
full, which can track holders as they enter and leave zones, partial, which tracks
holders only as they enter zones, and none, which does not track holders.
Accountability can also be used to detect passback violations.  The level of
accountability is defined when the system is configured. Accountability is also known
as "Tracking".
Alarm
A warning in the form of an audible tone and written phrase, appearing on an
operator's screen.  The phrase describes a system event which requires the
operator's immediate attention.
Alarm Call-up Time
The length of time that a display from a CCTV camera is "locked" to appear on a
monitor after it has been triggered by the generation of an alarm
Alarm Frame
The area on an operator's VDU in which up to four "top of queue" alarms can be
displayed
Alarm Queue
An area within the system in which alarms are held in order of their priority and the
time at which they were generated. Up to sixteen alarm queues can be maintained
by the system
Alphanumeric Character
Any character that can be entered using the keyboard, that is, letters of the alphabet,
numeric digits, and special symbols such as the hash (#).
Analog
Any measurable quantity.
Analog Point
A point which is used to hold a value which has been measured, rather than being set
to one of two or four states. The analog point is generally used to monitor plant
performance rather than in specific security applications; for example, where the rate
at which water is flowing through a pipeline needs to be recorded. In such a case, a
transducer can be used to measure the flow rate and convert it to an electrical
current. The current is then recorded, as a number, by the remote station and sent to
the master station.  It is then converted into the required engineering value and
stored in an analog point record.
Archive Rate
The rate at which timed archived data is transferred to disk.
