Normalize flow button
As each installation will require a different sampling pipe configuration, this function
is used to set the zero reference for the bargraph. This function is required to be
done during commissioning of the detector. The nominal flow value which is deter-
mined during the normalize flow period is then the zero set point value for the air-
flow monitoring during normal operation.
To use this function, use a thin tool such as a paper clip or a small jeweller's
screwdriver, place the tool into the hole and push the normalize flow button.
During the Normalization period the detector is still actively monitoring for smoke
using the default values.
