SECTION 2.2: PART 7
GASEOUS SYSTEMS
July 2008 37
Systems listed in this section have been tested to evaluate the following;
- Use of approved constituent gas components approved in Part 7: Section 2.1;
- The extinguishing concentration in accordance with ISO 14520-1 Gaseous fire-extinguishing systems.
Physical properties and system design. General requirements;
- Ability of the extinguishing agent at the design concentration to extinguish the fires and pass the
requirements of LPS 1230 Requirements for fire testing of fixed gaseous fire extinguishing systems;
and
- The Design Manual, Software Programme and Installation & Maintenance Manual specified in the
system approval Listing.
Notes:
1) Gases used for extinguishing fires are generally hazardous to health. In selecting a system, specifiers are
advised to carry out proper risk assessments based on the latest health and safety datasheets.
2) LPCB strongly recommends that the design and installation of these systems be carried out by a
Certificated LPS 1204 company (see Part 7, Section 1).

Fire Extinguishing System
Class A Standard (Solid fires
e.g. paper, wood, plastics)
39.7% Design concentration includes
30% safety factor
654b/01
Class A Cables (Solid fire
risks including cables)
44.3% Confirmation that minimum
safety factor is adequate
Class B (Liquid Fires e.g.
heptane)
46.0% Design concentration includes
30% safety factor
Design concentration Class A Standard and Class B = Extinguishing concentration x safety factor (minimum 1.3).
Design concentration Class A Cables System test concentration. Where this value is lower than the Class A Standard value,
the Class A Standard value should be used for design purposes.
Design concentrations are as tested to LPS 1230 in BRE Test Report Number 214668.
Extinguishing concentrations are as tested in BRE Test Report Number 214668 (ISO 14520-1 tests).
This system uses:
Design, Installation, Maintenance and User Manual: Fike manual, P/N 06-294, Issue May 2004.
Software Programme: Fike ProInert flow calculation Software, Version 6.2
a) This system is suitable for storage in environmental conditions from -20° to +50°.
b) System pressure is specified as 200 bar or 300 bar @ 15°C
