Insert the FAS-420-TM detection module into the pre-mounted housing base that has
been checked for correct wiring.
Replug the X4 jumper when inserting the detection module (PIN 1-2 or PIN 2-3, or vice
versa). Replugging will cause airflow calibration to be carried out automatically.
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 must 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.
Then enter the blowing out time and voltage of the blowing out and aspiration fan.
You can access the Help function by clicking the question mark to the right of the relevant
setting.
Click the appropriate aspiration point (A-E) for which the transport time is to be
determined.
Enter the preselection time necessary to reach 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 FAS-420-TM-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 FAS-420-TM-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 FAS-420-TM-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.
