Airflow monitoring

A pipe breakage or pipe obstruction is indicated in the "Fault messages" screen of the
diagnostic software.
Check airflow monitoring in accordance with Section 6.6 Checking Airflow Monitoring, page 80.
7.11

Malfunction Transmission

A malfunction is indicated on the FCS-320-TM and on the fire panel, where applicable.
F.01U.130.928 | 1.0 | 2009.11
In this case, check the pipe system for leaks and obstructions (see Section 6.6 Checking
Airflow Monitoring, page 80, "Troubleshooting").
If this check reveals no malfunctions, check the airflow monitoring by connecting the test
pipe and conducting the functional test in accordance with Section 6.7.2 Conducting the
Functional Test, page 82.
If, during troubleshooting, the pipe network has been changed, the original configuration
of the pipe network must be restored after the troubleshooting has been completed and
the airflow must be recalibrated.
Observe the current airflow value during ongoing maintenance or check it at the latest
during the next inspection.
If the target value is similar to the previous one, disruptive environmental influences are
the cause of the deviation. If these negative influences on the airflow monitoring cannot
be suppressed, increase the airflow range.
In the "ROOM·IDENT" screen, click the [Testing] button.
First select the preselection time and then click on the [Start] button to determine the
source of the fire.
The FCS-320-TM-R switches to the aspiration pipe blowing out. The appropriate smoke
aspiration point must be charged with smoke until the selected preselection time has
expired. Once the preselection time has expired, the smoke must be available at the
aspiration point for another 10 to 15 seconds.
Once the preselection time has expired, the FCS-320-TM-R switches to aspiration and the
aspiration point measures the time it takes until smoke is detected. Check that it is the
correct aspiration point.
