6.3.4 Normalize
Normalize procedure is used to set a new nominal flow reference based on the pipe network connected to
device, with this procedure the two thresholds for maximum and minimum flow are re-calculated and changed
according to the chosen tolerance.
Normalize procedure must be done during commissioning, when pipes are installed and drilled, to be sure that
the flow obtained is considered similar to the reference by FAAST FLEX that will update the flow tolerance
range accordingly with this value.
l If the flow is not normalized, the detector can report flow faults.
l If there is a change in the flow, we suggest checking if the are filters clean and pipeline’s integrity before
starting the normalization procedure.
Note: Before starting the NORMALIZE procedure, the pipe system should be connected and checked.
There can be no blockages, open pipes, dirty filters, dust, or other obstructions. The device should
be working for a minimum of 2 minutes and air flow must be stable.
