4. Installation requirements

Refer to the system design for the information of the room
installation, specifically for the construction works, ventilation, air
exchange, power supply system and the evacuation
of the exhaust gases of the diesel engine. The installation must be
carried out timely by specialists appointed by the client in
compliance with relevant regulations and provisions.
The main criteria for installing firefighting systems are described in
the EN 12845 standard. You also need to refer to the local
regulations if applicable.

4.1 Location

DANGER
Crushing hazard
Death or serious personal injury
‐
The system must be installed in an access-
controlled area. Make sure that only qualified and
authorised persons have access to this area.
‐
If the site is left unattended before the installation is
completed, all openings must be covered to prevent
children or any other foreign objects, such
as animals and stones, from entering.
‐
Use unbreakable covers that cannot be removed
without tools.
WARNING
Crushing hazard
Death or serious personal injury
‐
Leave necessary space in the technical room during
design for installing, using, maintaining and
disassembling the system.
‐
The design of the technical room must be carried out
by a qualified designer appointed by the client in
accordance with local regulations.
Before installation, make sure the following items are fulfilled:
• The technical room dimensions are adequate for the system
to be installed.
• The room has proper air circulation.
The system must be installed in a weatherproof room
protected from freezing. The room must be well ventilated to
ensure proper cooling of the electric motors and diesel engines.
Make sure that the operating conditions do not exceed those stated
in section Operating conditions.
Pay attention to the correct evacuation of diesel engine
exhaust gases. For this purpose, adequate ventilation ducts must
be installed.
The technical room of the system must be properly sized according
to existing regulations and good practices. You must take the
following into account:
• the overall dimensions of the system
• easy access to the parts of the system for commissioning,
routine checks and maintenance
• adequate air exchange in the room to ensure proper cooling
of the machines.
When sizing room openings for effective air exchange,
also consider the place of installation and the presence of
other machines or heat sources in the same room.
The installation of motors and engines in closed environments
always requires proper circulation of fresh air in the room to ensure
elimination of heat generated during operation and adequate
cooling of the machines.
Openings and ventilation ducts for hot air evacuation must be
dimensioned based on analytic calculation.
• Large openings must be protected to prevent people
or animals from entering.
• Use unbreakable protection that cannot be removed
without tools.
