4.4.10 Installation guidelines
Location of the extinguishing cylinders
The cylinders shall be placed if possible outside the protected area in a separate
proper and dry place. If the cylinders are stored in a corridor, safety precaution
shall be taken to avoid un-authorized manipulation of the extinguishing system
Installation of pipe network
Pipes and pipe connections shall be made of metal and be able to withstand the
maximal possible pressure. Sections of pipe which could be subject to static pres-
sure (closed piping) shall be protected by a pressure relief valve.
– The inside and the outside of the pipes shall be effectively protected against cor-
rosion, if needed by environmental conditions.
– To protect sensitive items e.g. books, paintings or documents from corrosive
particles in case of a discharge, galvanized steel pipe system must be used as a
minimum.
– Make sure that the pipe networks has been blown-out by compressed air in or-
der to avoid that any dust particle might be brought in the mission critical room
during the discharge of the extinguishing agent
– Bonding of pipe network to earth: Upon the triggering of a system, the friction of
any extinguishing agent in the pipe loads the agent with friction electricity and is
likely to generate electric arcs. The pipe must be earthed to prevent any risk of
striking between the pipe and the structure or even equipments. Size of bonding
wire is subject to specific regulations in conjunction with the type of incoming
mains supply. Please refer to local electrical regulations applicable.
Installation of nozzles
– Make sure that nozzles are positioned that no damage to protected object can
occur during discharge of the extinguishing agent
– Make sure that no nozzle is positioned so that out coming agent flow will be
blocked by any obstacles, air ducts or partitions which would lead to incomplete
extinguishing agent evaporation. Consequentially the correct distribution would
not be guarantied (this is specially important when using Novec 1230 and in
false floors and suspended ceilings)
