5.8.8 Structure 1563: Remote transmission device element
DOES NOT EXIST ANYMORE. The information content of structure 1563 can be
found in structure 1801.
5.8.9 Structure 1564: Alarmhorn (under area CAC control)
Abstract representation of an alarmhorn whose activation / deactivation is controlled by
the area CAC. The behavior is identical to structure 1561 (External horn).
5.8.10 Structure 1565: Alarmhorn
Abstract representation of an alarmhorn whose activation / deactivation can be user-
programmed. The behavior is identical to structure 1561 (External horn).
5.9 Hierarchical level: FUNCTION UNIT
Function units are devices on the internal bus (I-bus) of a CC11 control unit. Typical
function units are:
- Line modules
- Digital I/O modules
- Power supply monitoring units
Function units contain parallel information that cannot be combined into one unique
state. For this reason the information is mapped to two datapoints (ALARM and
FAULT).
5.9.1 Structure 1301: Function unit DS11-I line
Abstract representation of a DS11-I (interactive line). The function unit contains the two
datapoints ALARM and FAULT. The datapoints appear under the same ADF1/2 ad-
dress, however, with different sector ID. Together this results in a unique datapoint ad-
dress.
Datapoint ALARM (ALM)
1301/ALM: Addressing
Sector: FIRE
ADF1/2: Based on sequence number
1301/ALM: Valid states
State Description Valid commands
RESET
The function unit is not in the alarm sate.
ALARM
Collective alarm. An unidentifiable detector has responded.
Causes:
- Detector installed but not configured in the system.
- Due to a fault the detector cannot be identified individually.
