2-state monitoring The system’s input circuits are monitored for sealed and
unsealed conditions.
4-state monitoring The system’s input circuits are monitored for sealed, unsealed,
open, and short conditions. 4-state monitoring (also called input
tamper monitoring) is used in Challenger systems by default.
See “input tamper”.
24-hour alarm
Input types that will generate an alarm regardless of area status
(armed or disarmed).
4-Door/Lift DGP See “Intelligent Access Controller“.
Access The state of an area when it’s disarmed. The condition of an
area when it is occupied and when the intrusion detection
system has been set so that normal activity does not generate
an alarm. Opposite of “secure”.
Access control Control of entry to, or exit from, a security area. The Challenger
system typically controls access by allowing only authorised
users to unlock a door or to enter a lift.
Access test The access (disarmed) test is a defined interval during which
specific inputs may be tested to see if they are operating
correctly when the area is occupied. The input must be
programmed to be included in access tests (determined by the
input’s test type).
Access time The time that a door will remain unlocked after a user has been
granted access.
Acknowledge See “reset”.
Alarm The state of a intrusion detection system when a input is
unsealed and the condition of the area is such that state should
be signalled, for example, a door is opened when its area is
armed.
Alarm code The user’s full PIN (used for alarm control and optionally for
door control). See also “door code”.
Alarm code prefix digits The alarm code prefix value in the range one to four enables
users to enter a door code (a shorter PIN) for access control.
For example, if a user’s full PIN is six digits long (for example,
123456), and the alarm code prefix value is two, then the first
two digits are removed for access control, and the user can
operate doors by entering only the last four digits of the PIN (for
example, 3456).
Alarm control The control over alarm (arm and disarm) functions.
