Part 9
Only in the "disarmed" state, the entire event log, which stores all tripped detectors one after the other, all alarms as
well as all arming/disarming commands, can be read out by the ETS plug-in
(refer to "9. Event Log", page 56)
.
The alarm system can then change into the "fault" state if, for example, a sabotage contact was the detector which
has raised the alarm and if this detector is still open, a global fault has occurred, or if detectors are missing. You will
then have to separately reset the consequential fault. For this purpose, you need not call the fault message into the
displays once more and acknowledge it in those areas where the fault has already raised an alarm. To be able to
reset a fault message you must have eliminated the cause of the fault.
Even such faults which do not raise any alarm (e. g. mains voltage faults, battery faults or faults in the alarm trans-
mission device) will lead to the system changing into the "fault" state.
5.2.4
Alarm acknowledgement after a fire alarm
For resetting a fire alarm, a "0" telegram must be received from an 'authorized' bus device of any arming area through the
"arming input" ETS object. In this connection, the audible alarm indicators will be switched off if these are still active. The
flashlight and the fire signal alarm transmission device will remain active if they had been on at the time of resetting. The
flashlight can already be deactivated when the alarm is being reset if it was activated for a certain time only when the
alarm was being raised. In this case, the flashlight will be off in the "disarmed after alarm" state.
The "fire detector" safeguarding area will change to the "disarmed after alarm" state. You can also deactivate the
alarm by resetting it (only possible in configuration 1).
Important: Please note that both the alarm reset option and the actuated arming devices, for example, to reset a fire
alarm will act on other areas where they can reset signals or possibly disarm such areas.
Already during the fire alarm and after you have reset the alarm, you can view the event log in the display units, be-
ginning with the "alarm" message. For this purpose, it is assumed that the "fire detector" area will be visible in the
displays (can be set from the ETS plug-in). If any fire detectors have already been deactivated (closed) at this time
they will be displayed for a maximum period of 8 seconds when the event log is being processed.
All fire detectors which have raised the alarm will be displayed.

You can actuate one of the arming devices (disarm) again or reset the alarm to change back into the 'normal' ready
state. This will, however, only be possible if you have reset all tripped fire detectors. In this case, you can read the
tripped detectors in the fire detector areas of the display units with the addition "disarm", or "disarm" will solely be
displayed when detectors have already been deactivated (closed) again and the same have already been acknowl-
edged in the display units. It is not necessarily required to view the event log for a fire alarm on the display units, i. e.
to acknowledge the fire signals which, on the other hand, will be the only way to clearly recognize the tripping detec-
tors.
The visual alarm indicators (flashlight) will be switched off upon the return to the ready state at the latest. The fire
signal will be cancelled on the "fire alarm" EIB object and in the alarm transmission device ("ÜG-F" terminal).
Only in the 'normal' ready state, the event log which stores all tripped detectors one after the other and all alarms can
be read out by the ETS plug-in.
