4.5.2
Delay Time of the Alarm Triggering
The default delay time for the alarm threshold can be changed via the diagnostic software.
The default delay time for the alarm is set to 10 s. If the smoke level increases during
operation until it reaches the alarm threshold, the delay time starts to count down. The
message is transmitted only after the delay time has expired and the smoke level remains at
its current level. In this way, deceptive alarms due to brief strains (e.g. dust) can be
prevented.
4.5.3
Activation threshold of the airflow monitoring
The activation threshold for an airflow problem can be changed for the detection unit via the
FAS-ASD-DIAG.
Select the activation threshold in line with
Section 3 Planning, page 31
.
4.5.4
Delay time for an airflow malfunction
If you wish to change the delay time for transmitting the signal for an airflow malfunction, this
is possible via the FAS-ASD-DIAG.
The default delay time is set to 100 seconds. In areas with time-limited disturbance variables
(e.g. air pressure fluctuations), other delay times should be set based on the duration of the
disturbance variables.
4.5.5
Fault Indication
The collective fault display (airflow and detection unit malfunction) can be set to log or not to
log (default) trouble messages. Activation or deactivation is possible via the diagnostic
software.
4.5.6
Dynamic airflow
Activation or deactivation of dynamic airflow is possible via the diagnostic software.
4.5.7
ROOM·IDENT
Activation or deactivation of fire source identification is possible via the diagnostic software.
