Security area
What does "Activated internally" mean (
)?
"Activated internally" means that a security area is activated and people are in
the security area. This corresponds to the so-called perimeter monitoring.
Internal activation takes place, for example, on the wireless operating unit within
the security area. Devices with the setting "active when externally armed" (e.g.
wireless motion detectors) do not trigger an alarm when a detected event
occurs. Devices with the setting "active when internally and externally armed" (e.g.
wireless magnetic contact) trigger an alarm when a detected event occurs.
What does "Externally armed" mean (
)?
"Externally armed" means that a security area is armed and that no one is in the
security area. This corresponds to the so-called indoor and perimeter monitoring.
In the case of "Externally armed", a distinction is also made between the
inevitability factor and the lock function.
Inevitability factor
External activation is implemented by means of the activation device (key switch/VdS
outside of the security area). When the security area is activated, access to the
security area is blocked by means of a blocking element. It is only possible to enter
the security area if it has previously been deactivated using the activation device. A
built-in door module implements the inevitability factor. To avoid false alarms, the
inevitability factor is recommended.
Gateway function
External arming is carried out with the aid of the wireless control unit (within the
security area) and correspondingly configured detectors. In this case, after entering
the PIN, a defined exit delay begins during which the security area must be
exited. When entering the security area, the entry delay ensures that the security
area can be disarmed without first triggering an alarm.
