Fire detection and extinguishant system
•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.
