Introduction No pipe network (cabinet) heptafluoropropane gas fire extinguishing system is lightweight movable modern automatic fire fighting equipment, its high performance fire, fire speed, low toxicity, no fouling equipment, excellent performance of fire-fighting equipment, the control section It may dovetail with the fire control center.
Applications Cabinet heptafluoropropane gas fire extinguishing system is applicable to: computer room; archives;; fire protection station (transformer room), telecommunications centers, clean rooms and other key parts; and valuables library library.
System components No pipe network (cabinet) heptafluoropropane gas fire extinguishing system including storage bottles, starting device, safety relief valve, pressure gauge, cabinet, pressure signal, a jet short tube, nozzles, fire extinguishing agent according to the size of the storage bottle into Different models below to a company's non-pipe network (tank) fire extinguishing system, for example:
Edit this paragraph the system design and construction should follow the norms Gas fire extinguishing system design specifications GB50370-2005 gas fire extinguishing system installation and acceptance GB50263-2007 heptafluoropropane gas fire extinguishing system or fire extinguishing agent, is in line with the National Fire Protection Association (NFPA) developed NFPA-2000 specification requires clean gas fire extinguishing agent, which is characterized by 'non-conductive, highly volatile gaseous extinguishing agent, during use without leaving any residue', at the same time, heptafluoropropane fire extinguishing agent environmentally friendly, in the nature of the retention period is short, high efficiency and non-toxic fire, damage, applicable to the staff of permanent conservation area. in December 1996 after the detection of the National Testing Center, which is, and carbon dioxide are alternative Halon main products. Heptafluoropropane That FM200, fire extinguishing is the use of total flooding fire design, cast extinguisher, chemical fire main way design concentration within the range of fire-free status of the human body without harm (standard is generally 10%), but first you have to understand how the system works;.! there is a problem will be targeted to resolve; Second proposal required the discovery of fire extinguishing; whether it is automatic or manual under the conditions of; have let evacuation; and it must consider the following three aspects: First Heptafluoropropane itself has toxicity, when the concentration reaches more than 10% , discomfort occurs, a long time, there will be life-threatening. The second is to consider Heptafluoropropane decompose at high temperatures generated by the decomposition products may have harmful, this decomposition is mainly fluorine extinguishing agent In the presence of hydrogen elements will produce a pungent odor of hydrogen fluoride (HF). Even if the concentration is very small, will give a degree of discomfort and cause great damage. This decomposition products How much depends on the size of fire and Heptafluoropropane exposed to fire or heating surface length of time, if the accumulation soon reach the fire extinguishing agent concentration concentration, NA me the fire was quickly extinguished, there is very little decomposition. Third, the protected area may produce toxic substances on combustion personal injury is unpredictable Reference: heptafluoropropane (HFC-227ea) Clean gas fire extinguishing system design specifications section 7.0.2 Article extinguishing system should be set up automatic control, manual control and mechanical emergency operation three starts in the protection zone set up. prefabricated fire-fighting equipment should be automatic and manual control of two start-up mode. In the automatic control program, should arrange 0 ~ 30s adjustable delay injection part. Delay time is set, the protected area should be evacuated as soon as possible according to need security personnel ; usually no work for the protection zone can be set to 0s in extinguishing design concentration of greater than 9% of the protection zone, it should be added to the manual and automatic control of switching means when someone enters the protection zone, the fire extinguishing system switch to manual control. bit; when people leave, to return to automatic control bit 7.0.3 of automatic control devices should receive two separate fire signal to activate the manual controls and manual and automatic switching device should be located in the protection zone to evacuate. Exports outside the door for easy operation of local mechanical emergency operating device shall be located in the protected area between the reservoir bottle or local evacuation exit door for easy operation; and, its mode of operation should be completed in two steps Article 7.0.4 Fire fighting system. and the operation and control of prefabricated fire extinguishing equipment should include the need for opening the closure linkage, fans and dampers and other equipment operation and control features place the fire control center, movement information of each protection zone fire control system, should transmitted to the fire control center. This information includes information capture fire extinguishing operation, manual and automatic conversion and system failure.
