Fire source identification
NOTICE!
The term "ROOM⋅IDENT" is used in the DIAG diagnostics software for identifying the fire
source.
Fire source identification is activated/deactivated using the FAS-ASD-DIAG diagnostics
software via the "Settings" screen. The "ROOM⋅IDENT" function is deactivated as standard.
Main alarm following fire source identification
For certain applications, it is practical to perform the alarm signaling once the fire location
has been identified. To do this, the "Fire alarm after ROOM⋅IDENT" must be activated. It is
important to remember that when this function is activated, the "ROOM⋅IDENT" function must
also be activated; otherwise, the fire location cannot be identified.
The "Fire alarm after ROOM⋅IDENT" function is deactivated as standard.

Insert the FAS-420-TM detection unit into the pre-mounted housing base that has been
checked for correct wiring.
Change the X4 jumper position when inserting the detector unit (from PIN 1-2 to PIN 2-3,
or vice versa). By doing so, the airflow is automatically calibrated (see Figure 5, Page 4).
The green operation display flashes when the FAS-420-TM is initializing. If initialization is
complete, the operation display lights up permanently.
The airflow of the FAS-420-TM may not be influenced during the initialization phase.
Click the [Train] button. This opens the view with adjustable values used to determine
the transport times for fire source identification in areas A-E.
First enter the number of air sampling openings [Amount of aspiration points].
Then enter the blowing out time and voltage of the blowing out and aspiration fan [Blow
out time], [Blow out fan], [Intake fan].
You can access the Help function by clicking the question mark to the right of the
relevant setting.
Click the appropriate suction point (A-E) for which the transport time is to be
determined.
Enter the preselection time necessary to achieve the aspiration point and supply the
smoke. Once the selected preselection time has expired, the appropriate smoke
aspiration point must be charged with smoke. Once the preselection time has expired,
the smoke must be available at the aspiration point for another 10 to 15 seconds.
Using the smoke level, check that there is no smoke in the aspiration pipe.
Click the [Start] button. The FAS-420-TM-R/-RVB switches to the aspiration pipe blowing
out. The display of the aspiration point concerned is yellow.
Once the preselection time has expired, switch the FAS-420-TM-R/-RVB to aspiration. The
smoke must now be available at the selected aspiration point. The smoke level will
display if smoke is detected by the FAS-420-TM-R/-RVB. The display of the selected
aspiration point turns green and the determined time is entered. Teaching mode for the
selected aspiration point is exited.
