7 Terminology and abbreviations
AlgoRex®
Registered trade name for the CS11 fire detection system
Area
The system behavior is determined by the two alarm organizations “Day” and
“Night”. All system components that are controlled by a common alarm organization
belong to the same Area. The changeover of the alarm organization can influence
the operating states of the lower ranking system levels Section, Zone, and Element.
C-Bus
Fault-tolerant communications network for data exchange between the Stations.
CAC
Abbreviation for CERBERUS Alarm Concept. The CAC defines the behavior of the
security system control unit in Day and Night mode.
In Day mode remote transmission of alarms is initiated only after expiration of the
presence monitoring time (V1) or the alarm investigation time (V2).
In Night mode remote transmission of alarms and faults is initiated without delay.
CBD
See Station
CC11
Control unit station with the CS11. Maximum 4 per CS11.
CK11
Gateway station between the CS11 and a DMS7000 network.
CT11
Display terminal station within the CS11. Maximum 12 per CS11.
D-Bus
Sensor/Actor bus, starting at an IBD, allows operation of detectors and digital I/O
units.
DBD
See Device
Device
The detectors and actors on the D-bus are referred to as Device. These are only
visible via the affiliated Element.
DMS7000 network
Message-oriented communications network that allows data exchange between fire
and security controlunits and Cerberus or external management systems.
Element
Logical mapping of a Device. Supplies the higher ranking zone with current informa-
tion, e.g. danger levels.
Function unit
Devices on the I-bus are referred to as Function units. Typical function units are
detector line modules, emergency power monitoring units, digital I/O modules, etc.
I-Bus
Internal communications bus of a station. Provides the connection between the
station and the connected function units.
IBD
See Function unit
Logical tree
Data map of the logical / geographical CS11 structure.
Physical tree
Data map of the CS11 hardware
Section
Sections combine the states of several zones and represent these in a concentrated
form.
Sections allow collective operation of the corresponding Zones.
SeqNr
Represents the station-wide unique key of a tree node.
Station
Device on the C-bus.
StrucNr
Identifies the data type of a specific tree node.
Zone
Derived from the term Protection zone. The zone evaluates the information of the
affiliated elements and initiates an alarm, if required.
