Part 9
During the initialization phase, you can read the version number of the system software in line 1 of the display units,
while the text message "initializing" will be displayed in line 2. In addition, the green "Betrieb" (device ON) LED will be
blinking for the length of the initialization.
Within this time, the alarm central unit will send defined telegrams to the bus to store in the EIB objects of all outputs
values which correspond to the system state. In this connection, the alarm central unit will proceed by the following
rhythm:
1. All parameterized display units will be triggered: line 1 indicating the version number, line 2 reading "initializing".
2. All dynamic signals of the arming areas will be reset ("0").
3. The static armed/disarmed state signals will be set in accordance with the system state.
4. Pre-alarms and fire faults signals will be reset ("0").
5. All detectors of the individual safeguarding areas created in the ETS plug-in will be checked for their presence and
states one after the other by the EIB object numbers. In this connection, missing or open detectors in armed areas will
raise alarm. Missing detectors will raise a fault in disarmed areas
(refer to "7.1 Detector monitoring", page 53)
.
6. The "detector" and "sabotage" wired contacts will be evaluated and telegrams issued according to the states.
7. Subsequently, the "alarm", "ready for arming", "flashlight", "outdoor siren", "indoor siren", "fault" outputs and the
outputs of the alarm transmission device will be set in accordance with the system state.
8. This will complete the initialization. The green "Betrieb" (device ON) LED will be permanently lit.
Important:
Heartbeat check telegrams will already be transmitted during the initialization phase.
12. Storage Battery Management
An emergency battery facilitates uninterrupted operation of the load part of the alarm central unit, thus feeding the
directly connected external alarm indicators, if necessary, even in the event of mains voltage failure. An intelligent
electronic charging circuit ensures that emergency power supply of at least 12 hours will always be guaranteed.
Important:
The bus voltage and all detectors connected to the EIB will not be supplied by the emergency battery. Also to guaran-
tee uninterrupted operation in that case you should use an EIB emergency power supply system.
12.1
Battery check
The storage battery (lead gel) will be permanently kept charged. In this connection, the quality or the serviceability of
the battery will be checked at regular intervals by cyclic cell monitoring and end-of-life detection done by the electronic
charging circuit:
Cell monitoring:
Once a day, the open-circuit voltage of the battery will be measured for a short time. If the voltage measured falls
below 11 V the alarm central unit will generate a permanent battery fault signal. In this case, the battery is defective
and should be replaced as soon as possible.
If an open-circuit voltage of > 11 V is found by the measurement the battery is serviceable and will be kept charging.
