9. Event Log
The alarm central unit has an event log memory which is non-volatile in the case of mains or bus voltage failure, and
in which certain fault messages, events in the "fire detector" and "attack detector" safeguarding areas as well as all
events in armed areas will be saved.
The event log can take up a total of 400 entries. Each event represents an entry and will be logged in the areas con-
cerned. A fixed number of 40 entries each is always assigned to the "fire detector" and "attack detector" safeguarding
areas. The remaining 320 entries will be dynamically distributed in dependence of the configurations of the safeguard-
ing areas. Therefore, each area will be entitled to 80 entries if all four safeguarding areas have been enabled. If there
are only two safeguarding areas each area will have a capacity of 160 entries. One area can take up a maximum of
255 entries (if only one area has been configured).
The memory has been designed as a "shift register". After the memory limit of an area has been reached the earliest
entries will be overwritten by new events.
The following events will always be saved in the event log in dependence of the areas concerned:
•
"Disarmed"
"armed"/"armed"
"disarmed" state change.
•
Missing detectors in the safeguarding areas.
•
Alarm central unit sabotage contact open ("internal sabotage").
•
Tampering with the wired sabotage input ("external sabotage").
•
Mains failure (will be logged immediately after the failure).
•
Overloading of external alarm indicators.
•
Alarm transmission device fault (ATD checkback input)
•
Aborting heartbeat checking among alarm central units ("missing heartbeat check").
•
Battery fault.
•
Bus voltage recovery.
In addition, the following events will be logged for each armed area:
•
Alarms, i. e. all open detectors (immediate, delayed (not in the "pre-alarm" state), sabotage, wired) and program-
ming attempts.
Events in the "fire detector" and attack detector" areas will always be saved in the event log, regardless of what the
state is (with the exception of the detector test mode). Fault signals will not be logged for such areas.
From the ETS plug-in, you can read out and then print the event log under "configuration/read out event log…".
Each event will be identified by the exact time and date. In addition, the detector or the arming device which has
caused the event will be indicated.
In this connection, all entries will be output, sorted by the area, the date and the time.
Important:
- You can only read out the event log in the "disarmed" and "fault" system states.
- Detectors which have tripped in the detector test mode will not be saved in the event log.
- Although 'global' faults will not result in any fault signals in the detector test mode, they will be saved in the event log.
- After the complete programming (application download) of the alarm central unit, the event log will be deleted.
