Shutdown behaviour of the system
4.3.1
Shutdown behaviour during permanent and alarm recordings
The device distinguishes between two sources for a shutdown requirement (trigger for controlled shut-
down): Shutdown requirement through ignition (shut down signal) and also shutdown requirement
from another source (HD lock or detector e.g. input or motion detection). Depending on the triggering
source the behaviour differs in normal operation and at a current alarm recording as follows:
Trigger:
ignition (ignition or other shutdown signal)
Trigger:
other sources such as HD lock,
detector, digital input
Behaviour in
normal operation:
If the shutdown requirement is not
cancelled, the system processes the
configured system follow-up time (which
can be 0 seconds). If the requirement will
not be cancelled (restarting the device)
the system shuts down.
The device shuts down. This
behaviour has priority over the
system follow-up time.
Behaviour in alarm
recordings:
As long as an alarm is active, the device
records into the alarm archives (only in
the case of longer fitting detectors, not for
pulse detectors e.g. an alarm button).
If there is already a shutdown
requirement and the device is in the
system follow-up time, the follow-up time
will be “freezed” during the alarm and
post-alarm recordings.
After finish of the alarm the device
records into the alarm archives for the
configured follow-up time.
After the post-alarm duration the device
processes the configured system follow-
up time (which can be 0) or continues a
„frozen“ system follow-up time.
If the shutdown requirement hasn’t been
cancelled during this time, the device
shuts down. If further alarms occur in this
period the follow-up time will be frozen
again – the above described process
takes place again.
The device shuts down. This
behaviour has priority over
alarm or post-alarm recordings
and the system follow-up time
.
A shutdown requirement for the system using HD-lock switch, detectors and/or digital switch
inputs has priority over a currently ongoing alarm recording!
If an existing shutdown requirement will be cancelled before the end of the alarm (system will be
switched on again), the device doesn’t shut down – but turns into the normal operation mode after
processing the alarm and post-alarm time.
