Control Unit
An electronic board that is connected directly to readers, locks etc.,
and that contains a list of all the cards and rules that determine
whether a card holder will be allowed through a door.
ACU

Access
Level
List of readers and time patterns, that determine the access rights
of all card holders allocated to the Access Level.
Anti-
passback
A high security mode of access, where a card may be prevented
from being used at the same reader twice, thus preventing a card
from being passed back (through a window or turnstile) for use by
another person. A door with a reader on either side can utilize "true"
anti-passback where the card must be used at alternate readers. A
door with one reader can utilize timed anti-passback, where a
second presentation of the card is inhibited for up to 24 hours.
Alarm
An event which is treated differently from a non-alarm event, so as
to draw to your attention.

may be viewed after the 45-day limit that applies to Reporting and
the Event List.

to safeguard against loss or damage to the working database.
Controller
MICROgarde unit or Access Control Unit (ACU).
Card-holder
A person defined within the Card Holders section of the EXgarde
software. The person may not actually have a card issued to them,
or they may use only a PIN to gain access.
Card
In the context of the access control system, any number that
indicates the identity of a person. This may be a PIN with no
physical object associated with it.
Card+PIN
A higher-security access mode (compared with card-only), where
after presenting a card, a PIN (personal identification number) must
be typed in at the keypad next to the reader. Each card has its own
PIN, stored in the memory of the controller.
Digital input
An input that is connected to a device that can only signal "open"
and "closed"
Event
Message that is displayed as a result of a system process e.g. a
card is used, a door opens, an operator adds a card.
Forgiveness
An automated re-set of the anti-passback status of every card at a
set time of day.
Input
A connection to a controller that can be used to report a change in
another piece of equipment (usually a switch of some sort). An
input may be configured to monitor a "supervised" or "digital" circuit.
LED
Indicator light (abbreviation for Light Emitting Diode) fitted to
readers and controllers.
Mantrap
A high security mode of access, which can be enforced by a single
controller that controls two doors, and where the doors are fitted
