If no faults are detected, the functionality of the FAS-420-TM and/or the airflow sensor is
checked using the test pipe or diagnostic software (see
Section 6.7 Functional Test of Airflow
Sensors
).
If the airflow malfunctions are not displayed on the fire panel, proceed as follows:
Check whether…
–
the FAS-420-TM was programmed in the central fire panel program and the program was
transferred
–
the transmission path between the FAS-420-TM and the fire panel is working correctly.
If no faults are detected, the functionality of the FAS-420-TM and/or the airflow sensor is
checked using the test pipe or diagnostic software (see
Section 6.7 Functional Test of Airflow
Sensors, page 81
).
6.7
Functional Test of Airflow Sensors
Check the functionality using a test pipe and a digital precision pressure gauge and with the
aid of a PC and the FAS-ASD-DIAG Diagnostic Software.
A full functional test using the digital precision pressure gauge is described below. A limited
functional test can also be carried out without a digital precision pressure gauge.
