3.9.2 Trigger zones
The Zones button [B] accesses a screen that permits up to
three zones to activate the extinction phase when, within
one of the indicated zones, a certain number of alarms is
reached.
In order to select the zones, you must first activate one of
the three available options via the [D] check box, then tap
on the respective field at the side [E] to access the list of
configured zones. The arrow buttons [F] will allow you to
specify the number of alarms (maximum 3).
The image at the side shows how the system can be
configured so that the extinction channel is activated when
there are at least two alarms in zone 2.
3.9.3 Extinction input
The Inputs button [C] will allow you to configure the control-panel input points to activate the extinction functions.
EN12094-1:
To ensure compliance with EN 12094-1, the inputs in use must be on-board I/O or supervised inputs on
loop modules (such as the EM312SR module).
It is not possible to connect more than 32 devices to each of the selected input terminals.
It is necessary to specify the input associated with the "Manual Extinction" function (the others are
optional).
These functions are grouped into the following categories:
• Activate
This section provides the extinction-activation parameters.
The parameters of the "Manual extinction" command allow
for the selection of an associated group (loop 1, loop 2 or
one of the "I/O" terminals [G]), and the point [H] that
activates the release of the fire extinguishing agent in
accordance with the programmed pre-extinction time.
Selecting "--" for the group disables manual extinction on
the control panel.
• 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.
