The following table contains a description of the functions associated with the extinction that can be programmed for
the control panel inputs and outputs (on-board or on loops, through supervised outputs, such as those of the EM312SR
modules).

The input is activated in the case of pressure drop in the cylinders.
During stand-by status, its activation generates a fault warning.
After releasing the electrovalve, its activation is used to confirm the
release of the gas.
The input will be activated by a sensor that detects the flow of
extinguishing gas.
The flow may have been activated directly without following the
procedure of extinction and pre-extinction.
If this input is activated during the pre-extinguishment
phase, the extinguishment procedure will be aborted
