Auto-calibration of flow

1. Wait 15 minutes for the detector modules to complete initialisation.

2. Proceed with the auto-calibration of the nominal airflow phase:

Installer PIN code, Main menu, Settings, Detectors

3. In this section, select the first detector then go to Auto!, press “OK” and wait for the operation to finish.

4. If the second detector module is also installed, move up the screen within the same section until selected, then go back and press “OK” on Auto! to achieve auto-calibration on it.

5. Compare the nominal flow value obtained with that defined during the system design phase. If the values deviate by 20% or more, the speed of the aspirator can be changed (up to a maximum of ±1000 RPM) and the auto-calibration operations repeated.

6. Go to Save! and press “OK” to save the nominal flow values determined by the auto-calibration operation.

At the end of this phase an air flow measurement that falls within the fault thresholds must be obtained. If it is not so, it will be necessary to repeat the operations described in paragraph Inspection and verification.
