5. Operating the Alarm Central Unit
5.1 Display units
The alarm central unit can trigger various display units. Thus, the system states of the alarm central unit can be visual-
ized and signals polled through up to four independent display units. EIB objects, by means of which you can, for exam-
ple, trigger suitable info display units or display panels, are available for the coupling of the display units.
In this connection, you can trigger more than four display units by multiple configuration of the group addresses. In this
case, the information to be viewed will, however, be identical for the display units having the same assignments.
It is not necessarily required to use display units for the operation of the alarm central unit. Although you can operate
the system without any display units, it is not recommended to do so. So, for example, you can only clearly recognize
the reason why you cannot arm the system (open detectors) if you use display units.
5.1.1 Enabling the display units
Depending on the configuration, the ETS plug-in will automatically suggest the maximum number (up to four) of inde-
pendent display units.
Through the "display unit X available" parameter in the "display/display unit X" parameter branch, you can optionally
activate (setting = "yes") the display units created.
In this connection, you can assign an unambiguous identification text to each display unit. Such text has no limited
number of characters and is solely displayed in the ETS plug-in.
Furthermore, you can use the "displayed areas" parameter for the selected display unit in this parameter branch to fix,
in principle, which of the arming areas or of the "fire detector" and "attack detector" safeguarding areas can be viewed
in the corresponding display unit while the alarm central unit is in operation.
If you have activated only one display unit in your configuration please note that you will first have to view or acknowl-
edge various signals in the display units before you can reset them
(refer to "5.2 Arming/disarming and alarm ac-
knowledgment operations", page 44)
.
The "fire detector" and "attack detector" areas will only be visible in the display units if they have, in principle, been
enabled from the ETS plug-in (see above) and an event (tripped detector) has occurred in these areas.
Configuration 1 ("fire detector" and "attack detector" only) represents an exception. In this configuration, the "fire de-
tector" and "attack detector" areas will always be visible in the display units.
To enable the user of the system even in this case to get informed on signals of the alarm central unit, global fault
signals (mains voltage failure, battery fault, ATD checkback contact fault, abortive heartbeat check between two alarm
central units (if a missing telegram is to be evaluated in the same way as a fault), opening of the sabotage contact or
an interruption in the wired sabotage circuit) will also cause alarm central unit faults in this configuration. Such events
will only be indicated by the display units until they have been eliminated. Therefore, they need not be acknowledged.
In such case, no active alarm central unit fault signal will be transmitted through the EIB object or the alarm transmis-
sion device.
