Fire detection and extinguishant system
The following table contains a description of the functions associated with the extinction that can be programmed for
the control panel inputs and outputs (on-board or on loops, through supervised outputs, such as those of the EM312SR
modules).
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-extinguishment
phase, the extinguishment 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-extinguishment status,
the extinguishment procedure will remain locked until
the input resets. On input reset the pre-extinguishment
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-extinguishment 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-
Extinguishing
Output for the connection of a signal
relating to imminent discharge of the
extinguishing agent.
It will activate during the pre-extinguishment 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.

Note: The end of a stranded wire must not be
consolidated with soft soldering in points where
the wire is subjected to contact pressure.
2. Crimp the earth line wire to the eyelet terminal [B].
3. Attach the wire with the eyelet to the control panel using the
ground connection screw [C].
4. Ensure that the terminal “ ” of the power supply module
[D]], the motherboard [E] and the frontplate
[F]. of the cabinet are connected to earth system.
Attention: The protective earthing system must be compliant with the local safety regulations, fire codes, laws
and bylaws in force.
Note: A protective earth connection ensures that all exposed conductive surfaces are at the same electrical
potential as the earth surface, in order to avoid the risk of electrical shock if a person touches a device in
which an insulation fault has occurred. In the event of an insulation fault, a protective earth connection
will generate a high fault current which in turn will trigger an overcurrent protection device (fuse) and
disconnect the power supply.
5. Ensure that low-current safety or signal lines DO NOT come into contact with points with potentially dangerous
currents.
Using a plastic cable tie, bunch the wires together and secure them to one of the wire hooks on the back of the
cabinet

Note: The connection wires (to the mains supply and also any other wires inside the cabinet) must be secured
to the cable hooks on the backplate by means of plastic cable ties. Use cable with double isolation for
the connection to the electrical mains.
3.3.2 Connecting the batteries
The metal cabinet of the control panel provides housing for two 12V, 7 Ah lead batteries for the small version and 17 Ah
for the large version. The two batteries must be connected in series, in such way as to supply 24V.
1. Place the batteries into the battery compartment inside the cabinet (paragraph 2.2 - [Z]).
2. Using the battery wire ([A]), connect the batteries together.
3. Connect the wire coming from the power supply ([B] paragraph 2.2 - [T]) to the battery terminals ([C]).
Attention: Ensure that the polarity is correct.
Red - positive
Black - negative
Connection of the batteries before the mains voltage is present will not activate the system. Once the mains voltage is
supplied, the power-supply module will connect the batteries automatically and initialize the circuits which manage
them.
4. Position the thermal probe (paragraph 2.2 - [U]).
The thermal probe must be positioned on the side of the battery and held in place by a strip of tape ([D]).
