Functional description:
This EIB alarm central unit (ACU) is the heart of
an efficient alarm system. Owing to the utilization
of the Instabus EIB, expensive additional cabling
work can be reduced to a minimum. Both the EIB
system and individual detectors installed can, for
example, also be used by other trades.
By many different parameterization options
within an ETS plug-in of its own, the EIB alarm
central unit facilitates its use in various kinds of
buildings – from the detached family house with
outer shell and interior room safeguarding up to
the office building where up to four safeguarding
areas (SA 1…4) can be protected individually or
as groups linked up with one another. The ETS
plug-in will be automatically started when the
parameter setting option is called.
The EIB alarm central unit stands out for the following performance features:
•
Up to 160 detectors can be managed and integrated into up to four separate safeguarding areas.
•
All sensors (detectors) are connected to the alarm central unit via the EIB. This facilitates individual identification
and monitoring of all detectors.
•
All events (arming, alarm, fault) will be logged together with their date and time and saved.
•
The alarm indicators (siren, flashlight, alarm transmission device (ATD)) can be directly connected to the alarm
central unit or triggered via the EIB.
•
A rechargeable emergency battery facilitates uninterrupted operation of the alarm indicators even in the event of
mains failure. An intelligent electronic charging circuit ensures that emergency power supply of at least 12 hours
will always be guaranteed.
•
Display and operation are exclusively decentralized and can be handled via external EIB devices (info display unit,
pushbutton sensors, etc.). Sometimes, several types of arming devices (AD) can be used within an arming area
(AA 1…AA 4) for arming and disarming.
•
A local detector input (wired detector) can be used for safeguarding the place of installation of the alarm central
unit, e. g. in a distribution cabinet. Thus, the alarm central unit will be in a position to protect 'itself'.
•
An additional relay contact in the form of a potential-free output can, for example, be used for additional alarm
indicator applications.
For fire and attack detectors, separate safeguarding areas are reserved. If a detector from one of such safeguarding
areas responds an alarm will immediately be raised, regardless of the state of the system.
As a special variant, the alarm central unit can also be solely used for attack and fire detector applications.
A detector test mode is available, by means of which all detectors of the alarm system can be checked without rais-
ing any alarm.
Particularly large buildings (arcades, extensive factory units) can possibly not be safeguarded by one alarm central
unit alone but require several alarm central units, each of them monitoring partial complexes. When several EIB
alarm central units are used, such alarm central units can monitor one another by sending and receiving telegrams
for mutual monitoring. After three missing telegrams from the 'partner alarm central unit', a sabotage signal will be
released (armed: alarm, disarmed: fault).
