Nitrogen (N 2) extinguishing agent Characteristic of nitrogen (N 2) Room ambient Agent: clean Nitrogen 79 % Extinguishing principle: displacement of Oxygen After extinguishing Nitrogen 89% Approx. Extinguishing concentration: min 30% < 14. 5% O 2 Oxygen Storage stage: as expended gas Effect on people: harmless 21% Oxygen 10 -12% (due to not having medical effect on blood supply) Page 2 April 2010 Building Technologies

Inert Gas Extinguishing Inert gas systems aim to drop the O 2 to between 10% and 14%. Ideally inert gas systems aim for ca. 12. 5% O 2 Page 3 April 2010 Building Technologies

SINORIX CDT 300 bar regulated • Nitrogen: Main component of air, inert and odourless • Extinguishing agent which works by reducing the oxygen level (< 14%) • Ecologically clean ODP = 0 (Ozone Depletion Potential) GWP = 0 (Global Warming Potential) • Does not create breakdown products in contact with a naked flame • Siemens was the first to have the idea of using nitrogen as an extinguishing agent Page 4 April 2010 Building Technologies

SINORIX CDT 300 bar regulated • 60 second discharge with extinguishing before the end of the discharge. • Pipework pressure < 100 bar • Centralised system with optional directional valves • Modular system for protection of small enclosures • Using 40. 3% of nitrogen reduces oxygen level to 12. 5%, which equates to air breathed at an altitude of 3, 500 m. Page 5 April 2010 Building Technologies

Sinorix CDT: The best solution compared with gas blends Unlimited access to natural gases Not dependent on specialist suppliers - Natural gas blends are available from only a limited number of suppliers No extra costs for an inert gas without extinguishing benefits - No patent costs for N 2, Ar and CO 2 - The price of a gas blend is about 5 times that of a single gas No CO 2 in SINORIX CDT (Unlike IG-541, which contain CO 2) Page 6 April 2010 Building Technologies

SINORIX CDT 300 bar regulated – Key points • Excellent extinguishing performance for Class A, B and C fires - best solutions for rapidly spreading fires - excellent performance on liquid and gas fires • Electrically non-conductive - safe for electronic risk • Using inert gas - no residues after a discharge • Excellent performance on deep-seated fires with a retention time of 20 minutes - suitable for archives Page 7 April 2010 Building Technologies

SINORIX CDT 300 bar regulated What does CDT mean? Constant Discharge Technology New constant (or regulated) flow technology: Discharge pressure is almost constant, whatever the container pressure. Technology developed in house by Siemens SAS and manufactured by Production Extinction Siemens SAS. All the accessories too (e. g. : Pressure switch, Manual actuator, …. ) Page 9 April 2010 Building Technologies

SINORIX CDT 300 bar regulated Benefits of the SINORIX CDT regulated nitrogen system SINORIX CDT regulated nitrogen at least one third fewer containers compared with a 200 bar system. More than 50% less overpressure venting area compared with an unregulated system. pressure downstream of the valve VFR 300 -S less than 100 bar. Page 18 April 2010 Building Technologies

SINORIX CDT: A modular system As well as centralised systems, SINORIX CDT also allows you the option of modular systems The benefits are: • No pipework • No nozzle orifice drilling calculation • Installation in existing premises without disturbing the user • Cost Page 19 April 2010 Building Technologies

SINORIX CDT 300 bar regulated Examples of applications of the CDT system: • Computer room • Anechoic chamber • Electrical rooms • Solvent storage • Cold rooms • Deep-seated fires • etc… Page 20 April 2010 Building Technologies

SINORIX CDT International Approvals Nitrogen is recognised by the following organisations: - Authorities and Laboratories: Vd. S, LPC, FM, UL, CNPP, HK-FSD, etc Agreement by the French Ministry of Health to the use of nitrogen as an extinguishing agent in the presence of people - Standards: CEA 4007&4008/NFPA 2001/UL 2127/ISO & CEN 14520 Siemens introduced nitrogen as an extinguishing agent on the international stage for 4 years Page 21 April 2010 Building Technologies

SINORIX CDT - Approvals The IEAG APSAD Gas Committee issued a favourable opinion on Nitrogen 300 bar systems since December 2004 More than 10000 bottles installed since 02/2005 Vd. S approved S-number + G-numbers Page 22 April 2010 Building Technologies

SINORIX CDT 300 bar regulated All extinguishing systems using an inert agent need an overpressure vent to avoid damage to the protected enclosure. Even though the SINORIX CDT system uses a new constant flow technology, reducing the venting area required by 70%, you must still provide overpressure venting. Siemens FR has developed its own overpressure vent 1 hour fire resistant GRIFEU 0, 1 EVENT 0, 1 Page 23 April 2010 GRIPRO 0, 1 Building Technologies
