8. Disable auto calibration

   Off = auto calibrate enabled, on = auto calibrate 

disabled
If this switch is set, then the normal power-up calibration of the detector is bye-

passed and the last stored values are used. This applies to both the airflow calibration 

and the ClassiFire histogram data. It is often beneficial to set this switch once the 

commissioning is complete so that in the event of a power cut, the detector does not 

re-calibrate itself. If the detector is to be moved to a new location, or if its environment 

has changed for some other reason then it is advisable to cycle the power with this 

switch off so that the detector does recalibrate itself.

Notes:

1. Changing alarm factor starts a new FastLearn.
2. Changing the flow limit offset starts a new flow calibration followed by a flow limit 

setup.
