3. Connect the test pipe.
4. Connect the pressure measuring hose to the adapter connection B. When carrying out a
limited functional test without a digital precision pressure gauge, the connection for the
pressure measuring hose on the test pipe must be closed.
5. Connect the 4-pin plug of the adapter to the digital pressure gauge.
6. Connect the PC to the FAS-420-TM through the diagnostic appliance and start the
diagnosis program. You can use the diagnosis program to track the airflow values and the
fault messages during the functional test.
Information for installing the diagnostic software can be found in Section 6.1 Preparation,
page 76.
6.7.2 Conducting the Functional Test
1. Close all the test pipe’s aspiration borings with some duct tape.
After a short run-up time, the negative pressure produced by the FAS-420-TM must be
80 Pa. This step can be omitted if a limited functional test is carried out without a digital
precision pressure gauge.

NOTICE!
The airflow range and fault delay settings must be configured via the FSP-5000-RPS
configuration tool on the fire panel. To configure the settings with the diagnostic tool, the
setting in the FSP-5000-RPS configuration tool must be set to "Programmable".
NOTICE!
On completion of the functional test, the original settings must be restored. You should
therefore record this data (e.g. using the log for the device as a saved text file).
NOTICE!
Once the aspiration borings have been closed, the device reports the malfunctions "Air flow
too low (static evaluation)" and "Detector module fault" within 30 seconds.
