Configuration manual
• Disable
This section provides the parameters of disabling the
extinction procedure. There are 3 different modes available
for disabling the extinction procedure, each one attributable
to a different input:
- Disab. Extinguishing: disables all the extinction
functions
- Disab. Man. Exting.: disables the programmed inputs
for manual activation of the extinction procedure
- Disab. Aut. Exting. (option 4.23 "Manual only mode" of
EN 12094-1): disables the automatic-activation of the
extinction procedure
The parameters of the 3 different disablement modes allow for the assignment of a group (loop 1, loop 2 or one of the
terminals "I/O" [G])) and the point [H] which activates the related extinction-disablement mode.
Selecting "--" for the assigned group disables the related extinction-disablement mode.
• Flow/Pressure
This section provides the parameters for the functions of
the "Pressure switch", "Pressure switch confirm" and "Flow
switch" that can be associated with three different inputs:
- Pressure switch (option 4.19 "Monitoring of the status
of components" of EN 12094-1): input for the
connection of a pressure valve that activates in the
event of low pressure in the cylinders
- Flow switch (option 4.18 "Signal representing the flow
of the extinguishing agent" EN 12094-1): input for the
connection of a flow sensor, the activation of which
signals the release of the fire-extinguishing gas
- Press. switch Confirm: input for the connection of a
device used to verify the release condition of the fire-extinguishing gas by means of the pressure switch
The parameters of the 3 different functions allow for the assignment of a group (loop 1, loop 2 or one of the terminals "I/
O" [G])) and the point [H] associated with the extinction function.
Selecting "--" for the assigned group disables the related function type.
3.9.4 Extinction outputs
In order to configure an output for the extinction function, you must associate it with one of the default groups prepared
for this purpose, and described below.
EN12094-1:
You must use on-board I/O or supervised outputs on the loop (such as the EM312SR module or sounder/
flashers on the loop).
You must provide outputs associated with the following functions (the others are optional):
-Electrovalve
-Pre-extinction
-Release
The "Electrovalve" function can only be associated with the output corresponding to the "I/O 4" terminal on the
motherboard of the control panel.
The default "Pre-Extinction" function is associated with the output corresponding to the "I/O 3" terminal on the
motherboard of the control panel.
