1. Check the system after installation using the FAS-ASD-DIAG Diagnostic Software.
2. The unit must be operated for at least 30 min prior to the airflow being initialized to bring
it up to operating temperature.
3. To initialize the connected pipe system, press the S2 flow-init button (see Figure 5,
Page 5) on the detector module concerned until the green operating LED on the unit
starts to flash. Initialization is complete after approx. 10 seconds. Following successful
initialization, the operating LED lights up permanently.
4. No further modifications may be made to the pipe system during or after initialization.
The unit's fan voltage must also remain unchanged following initialization. Otherwise, the
initialization procedure must be repeated.
Troubleshooting Using Flash Codes
Malfunctions and unit statuses are indicated via the flash codes of the detector module LEDs:
Technical data
