6 Description and function
6.1 General description
The fire extinguishing units in the SiFire series are
built in several variants and models, as indicated in
our catalogues, or in versions modified in order to
satisfy particular customer requirements (trans-
port/handling difficulties, particular perform-
ances, etc), using the main components described
below:
• main normalised “back pull out” pumps, coupled
to an electrical motor or diesel engine by a spacer
allowing the dismantling of the pump and/or
motor without having to work on the other. It also
allows the extraction of the rotating part of the
pump for maintenance without having to remove
the motor and/or the end suction pump housing.
• vertical multistage jockey pump for correcting
small losses and for keeping the system pressure
constant.
• electrical control panels for the main and jockey
pumps (one per pump).
• piping and discharge manifolds in steel.
• valves on the pump discharge that can be locked
in the open position.
• non-return valves on the pump discharge.
• butterfly valves, manometers, pressure switches.
•Connectionforflowmeter to control the perform-
ance of the pumps.
• double pressure switch circuit for start-up of the
main pumps and control of the working order of
each individual pressure switch.
• pressure switch for automatic start-up of the
jockey pump.
• support frame(s) for control panels and manifolds.
• independent fuel tank for the diesel engine, com-
pleted with accessories.
• Two batteries for the start-up of the diesel engine
(if present).
The system is assembled on a base frame in
accordance with the EN 12845 standard, within
the limit of delivery, indicated on installation dia-
gram from fig. 2a-2b.
Each pump is installed on a steel base frame. Die-
sel pumps are connected to hydraulic elements
with intermediary vibration damping joints to
avoid the transmission of vibrations from diesel
motors but also the possible piping or mechanical
structure breaks.
For connection to the public water distribution,
rules and existing standards must be respected,
and possibly completed with rules of water distri-
bution companies. Besides, local particularities
have to be taken into account, for example a too
high or too variable suction pressure which
requests the assembly of a pressure reducing
valve.

6.3 Function of the product
The operational logic for the fire extinguishing
unit is based on the cascade calibration of the
pressure switches for pump starting. The jockey
pump of pressure boosting is the first to start and
maintains the system full of water and under pres-
sure. It starts when the pressure drops in the sys-
tem. Start and stop control is set up via the
suitably calibrated pressure switch.
When a larger quantity of water is requested, due
to the opening of one or more circuits or due to a
broken sprinkler, pressure decreases in the sys-
tem. This drives the main pump to start.
For systems with more than one pump, if the main
electric pump does not start, due to electricity
problems for example, the drop in pressure will
activate the standby pump pressure switch which
starts the diesel engine. In some cases, two or
more electric pumps could be used.
Once the sprinkler circuit or the gate valve that
supply the sprinkler system is closed, the system
reaches the maintaining pressure of the installa-
tion; it will be necessary to press the –Stop– but-
tons on panels to stop the main pump and standby
pump. The jockey pump is automatically stopped.

7 Installation and electrical connection
DANGER! Risk of electric shock!
Personnel dedicated to the connection of elec-
trical equipment and motors must be skilled for
such work. They shall make the connection
according to the wiring diagrams supplied, in
accordance with regulations and laws in force. In
addition, they must ensure that they have shut-
down power before performing any operation
which provides the possible contact with the
electrical parts . Check earth continuity.
7.1 Installation
Install the booster in an easily accessible room,
ventilated and protected from rain and frost.
To make sure that the booster can pass through
the room door.
For maintenance works, a sufficient place must be
provided. The unit must be easily accessible.
Installation place has to be horizontal and flat. It
must be robust enough to support the system
weight.
The room must be exclusively dedicated to fire
equipment, directly accessible from the outside,
and having a fire resistance of at least 60 minutes
(see standards).
The room must be, in order of preference:
• separate from the protected building (isolated)
• closed to the protected building
• Inside the protected building.
NOTE:
For rooms with closed walls or inside the building,
it is preferable to have a fire resistance superior to
120 minutes. The temperature inside the room
must not be less than 10 °C (4 °C in the presence
of electric pumps) or more than 25 °C (40 °C in the
presence of electric pumps).
The room shall be equipped with openings to the
outside to ensure adequate ventilation for cooling
engines (electric and diesel) and for diesel engine
combustion.
The room also shall be equipped with a sprinkler-
type protection (EN 12845).
Sprinkler protection can be directly supplied by
the discharge manifold of the booster, as required
by the EN 12845 standard.
Access to the room must be guaranteed and easy
for people, even if the installation of fire is on,
without light, if there is snow or rain, and in any
case that can affect access negatively. Access to
the room must be sufficiently reported and admit-
ted only to authorised, specialised and properly
trained personnel.
Avoid access to the system for unauthorised
persons!
The booster is a fire equipment using AUTO-
MATIC START and MANUAL STOP ONLY. For this
reason, there must have a clearly visible sign in
the system room warning that this logic opera-
tion makes the possibility of an unexpected auto
start.
The pump unit is NOT equipped with emergency
stop. The main pumps can only be manually
stopped (see corresponding manual of control
box).
For this reason, before an intervention on group
of pumps, make sure you switch off power sup-
ply and avoid any start of pumps.
If possible, pumps must be installed under the
charge of water. They are considered as such if
at least two thirds of the actual capacity of the
suction tank is above the level of the axis of the
pump and the minimum useful level of the water
in the tank is not more than two meters below
the axis of the pump.
If the conditions mentioned above are not
respected, the booster is considered on suction
conditions, which are accepted after installation
of special devices, explicitly described by the
standard (priming tanks, separated pipes suc-
tion, etc).
7.2 Safety recommendations
WARNING! Risk of Cut!
Do not remove the protection on any rotating
parts, belts, hot surfaces etc. Never leave tools
or disassembled parts of the booster on it or
around it.
DANGER! Risk of fatal injury!
Do not remove the protection of live parts. Pre-
vent each possibility for operate any element
that isolates the installation or subassemblies
on which to work.
Take all precautions to avoid a risk of electrocu-
tion. Control earth connection, presence and
continuity, and if a device for protection against
indirect contact is installed (differential switch).
If necessary, make operation on the unit by
using required equipment (insulating gloves,
isolating base plate).
Never leave the electrical panel or the terminal
box of electrical motor powers opened. Check if
there is no possibility of contact with live parts.
Check if electrical connections and auxiliary
power are correctly connected. Check the label
