Installation manual
General Description 15
The following table contains a description of the functions associated with the extinction that can be programmed for
the control panel inputs and outputs.
EN12094-1: To guarantee compliance of the product to EN 12094-1, the control panel must be configured to make
available the following functions (the others are optional):
Manual extinction, Electrovalve, Pre-extinction, Release.
The “Electrovalve” function must only be associated with the “AUX” terminal on board the control panel.
Refer to the Configuration Manual for the programming details of the other functions.
Terminal function Activation
Pressure
switch
Input for the supervision of the pressure
of the cylinders containing the gas.
The input is activated in the case of pressure drop in the cylinders.
During stand-by status, its activation generates a fault warning.
Confirm
release from
pressure
switch
Input, for the connection of a pressure
switch, confirming the release of the gas
from the cylinders.
After releasing the electrovalve, its activation is used to confirm the release
of the gas.
Flow switch
Input, for the connection of a flow
sensor that will signal the release of the
gas from the cylinders.
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.
Stop
extinction
The inputs stop the extinction procedure
in accordance with the activation mode
described opposite.
Abort
If this input is activated during the pre-extinction phase, the
extinction procedure will be aborted even if the input resets.
The procedure can be restarted only after control panel reset.
If this input is activated during stand-by, it will generate a fault
warning.
Add
If this input activated during pre-extinction status, the extinction
procedure will remain locked until the input resets. On input reset
the pre-extinction countdown will refresh and restart.
If this input is activated during stand-by, it will generate a fault
warning.
Hold
If activated during a pre-extinction condition, the extinction
procedure is stopped but the pre-extinction time count
continues. When the input is restored, if the pre-extinction time
count has terminated, the gas will be released.
If this input is activated during stand-by, it will generate a fault
warning.
External
This function is identical to the “Hold” function but refers to
mechanical or electrical intervention (for example, a door
contact that inhibits gas discharge, etc.).
This activation will be signalled separately.
If activated during stand-by, it will not generate a fault warning.
Manual
extinction
This input is for the connection of one or
more manual call points for the activation
of extinguishing-agent discharge.
Electrovalve
Output for the connection of the
electrovalve which discharges the
extinguishing agent.
It will activate only when the pre-extinction time expires
Stop
extinction
active
Output for the connection of stop-
extinction signalling devices.
It will activate when the extinction channel is stopped by one or more inputs
connected to the “Stop extinction” input.
Pre-
Extinction
Output for the connection of a signal
relating to imminent discharge of the
extinguishing agent.
It will activate during the pre-extinction time which runs before the discharge
of the extinguishing agent.
Release
Output for the connection of signalling
devices which warn building inhabitants
of the actual discharge of the
extinguishing agent.
It will activate on activation of the electrovalve.
