• Deactivate
This section provides the parameters for stopping the
extinction procedure. There are 4 different modes available
for stopping the extinction procedure, each one attributable
to a different input:
- Stop Extinct. ABORT (Option 4.27 "Emergency
interruption device" of EN 12094-1): stops the
extinction procedure definitively
- Stop Extinct. HOLD (Option 4.20 "Emergency hold
device" of EN 12094-1): stops the extinction procedure
until reset (which restarts the pre-extinction time)
- Stop Extinct. ADD (Option 4.20 "Emergency hold
device" of EN 12094-1): stop the extinction procedure
until reset (the pre-extinction time-counter will not be
altered)
- Stop Extinct. EXTERN (Option 4.19 "Monitoring the status of components" of EN 12094-1): same as "Stop Extinc.
Hold", but activated without human intervention (for example by a door contact that inhibits the release of gas)
The parameters of the 4 commands 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 relative stop-extinction mode.
Selecting "--" for the assigned group disables the related stop-extinction mode.
EN12094-1:
If the "Stop Extinction ABORT" function is utilized with a Previdia Compact control panel, the "Stop
Extinction HOLD" and "Stop Extinction ADD" functions cannot be associated with inputs, and vice versa.
• 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. Extinction: disables all the extinction functions
- Disab. Man. Extinc.: disables the programmed inputs
for manual activation of the extinction procedure
- Disab. Man. Extinc. (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.
