How is China FM200 Gas Fire Suppression System Like

Foreword

The FM200 fire suppression system is a fire extinguishing system that with high efficiency in fire extinguishing, its agent is HFC-227ea which is an odorless, colorless, non-toxic,non-corrosive fire extinguishing gas agent and is a synthetic fire suppression agent, which is also environmentally friendly with ODP=0, ALT=0, GWP=0, good in insulation, no pollution to the environment and durable and reliable in performance, it is halon1211 and halon 1301 alternative.

It is well-known that can extinguish the fire within 10 seconds, very rapidly.
and it extinguishes the fire by removing the free radicals
or heat elements of the fire triangle (oxygen, feat, and fuel).

WARNING

• 1.  The condensed atomized discharges can be produced when HFC-227ea is discharging. The extinguishing agent can be carried out when the burning chain is broken off; The extinguishing agent is fast, if the equipment is used at places where people work, the delay in equipment is necessary and personnel must withdraw from such places during the delay time.
• 2.  The user organization must set obvious warning signs at the following parts and it is suggested to use the following words on such signs:
  a.: Signs in production areas: Warning! All personnel must withdraw at once after hearing the alarm bell at the site.
  b.: At parts of emergency start button: Warning! Ensure there are no people in the protection area.
• 3.  Except for the above warnings, Other security measures must be confirmed to extinguish relevant provisions of the state.

in earlier days we published one article with topics of  FM200 chemical-based gaseous fire suppression systems, today this article we want to explain more about it.

Introduction of FM200 gas fire suppression system and its agent

FM200 or “HFC-227ea is a clean gas agent mainly with chemical fire suppression characteristics and auxiliary with physical fire suppression characteristics, it is colorless, odorless, non-toxic, and non-conductive and does not have any pollution to the protected material, so it is electrically friendly. it is with low concentration to suppress the fire, to suppress fire under class B, Class C, and Class E (electrical fire), in normal temperature it is stored in liquid form, after suppression it has no residue left, furthermore it is zero value in ozone-layer depletion potential, it stays in the atmosphere for 31-42 year meet the environmental requirement.

as fm200 does not have chlorine and bromine, will not cause any damage to the atmospheric ozone layer, so from its birth date it is for replacement of halon 1301 and 1211 products, it is very suitable to install in the computer room, data center room, server room, generator room, telecommunication room, normally these place will install a storage cylinder with the hfc-227ea agent on the floor top or in the cylinder storage room when fire causes, the hfc-227ea agent will run out of from their nozzle and rapidly exhaust oxygen and cool the fire scene, to achieve the purpose of fire protection.

Composition of FM200 Gas Fire Suppression System

fm200 fire suppression system is normally made up of an automatic fire alarm control system, extinguishing agent storage cylinder, pilot gas cylinder, head container valve, safety valve, electromagnetic valve, selector valve, check valve, pressure switch, installation bracket, nozzle, piping fittings, siphon these main components and accessories.
According to the use requirement, it can be divided into a “unit independent system”, a “combined distribution system”, it also can be divided into a ” piping system” a “non-piping system”, “piping system” also have “large complex piping system” and a “simple fire detecting tube system”, “non-piping system” also can be divided into ” cabinet type” and ” hanging type”.

4 Main Pipeline Systems

In the market, piping type one, cabinet type one, fire detection tube one, and hanging type are 4 main modes, there are different installation methods, storage capacities, and applications:

• Firstly, for installation, the piping type one is installed in an additional cylinder storage room; the cabinet one is installed in the protection zone; the fire detection tube one is installed on the protection objects and the hanging type is installed on the top of the ceiling.
• Secondly, for storage capacity the piping one can take loads of 40 liters, 70 liters, 90 liters 100 liters, 120 liters, 150 liters, and 180 liters; the cabinet type is the same as the piping one; the fire detection tube one is 3 liter and 6 liter; the hanging type is 10 liter, 20 liter,30 liter and 40 liter.
• Thirdly, for application, the piping one is normally for big space fire protection, such as a big computer room, or big data processing room; the cabinet one is normally for medium-sized space fire protection; the fire detection tube one is for small machinery equipment or electrical equipment, such as power generator, control cabinet; hanging type is for all bigger or smaller space fire protection, it is flexible to install because it is installed on the ceiling or the side wall.

Advantages

• Advantage 1, please see described above “Introduction of fm200 gas fire suppression system and its agent”.
• Advantage 2, it works with the mature fire alarm system, the fire control panel has a display of time delay,
  and it can find and detect fire at its early stage.
• Advantage 3, is a complete fire control system, many protection zones can fulfill functions of manual operation, automatic operation, and mechanical operation, and gas agent extinguishing time can be delayed 30 seconds or more, to ensure human safety and property safety.
• Advantage 4, China approvals to support, normally in China test reports, and CCC certificates are necessary for these products, and in the international market, a UL, CE, DNV, or FM approval is very necessary.
• Advantage 5, We can refill the heptafluoropropane fire extinguishing agent multiple times, so overall it is cost-effective.

Application

HFC-227ea fire suppression system has a wide range of applications, in china 60% above of gas fire suppression systems are hfc-227ea, the application places are as below but not limited to:

• Computer room.
• Telecommunication room.
• Archives office, museum historic building, and library.
• Precision Electronic Instrument room.
• Relay Signal Building.
• Medical Equipment.
• Industrial Equipment.
• Oil tank.
• Flammable liquid storage area.
• Train, bus, and vessel vehicles.
• Power generator and distribution room.
• Army warehouse.
• Workshop.
• Other machinery Places or high-value sites.

Precautions

• When people are at the site, they require the fire control panel to delay 30 seconds, so that people have enough time to escape before the fire suppression system works.
• The user should set it with ” Warning Sign“, the poster words should be as below:
  a. warning sign in the protection zone, should be “Warning! When you hear the alarm bell alarms, personnel should leave immediately”.
  b. in the manual call point button location, should be “Warning! When using mechanical operation please make sure none personnel is in the protection zone”.
  C. Except the above “Warnings”, other safety measures should be as per national or local regulations.
• HFC-227ea fire suppression system is not suitable for below places:
  a. nitrocellulose and black gunpowder place.
  b. Reactive metals storage and workplaces, like potassium, sodium, Magnesium, Titanium, and Uranium.
  c. Storage place of metal hydride.
