Fm200 calculation

Number of FM-2Cylinder Required This calculation tool is intended for use in developing approximate estimates of the material and equipment budgeting purposes. It shall not be used as a substitute in determining material and quantity requirements as defined in Kidde Fire Systems design manuals and applicable NFPA standards. Step Identify the hazard to protect and note the applicable design concentration number. Example: Hazard is Class (Electrical) = 7. Round up to whole number = L = ft. The FM-2material properties and the chemical formula CF3-CHF-CFor C3HFa boiling point of -16.

Class C Fires : Fire that involves energized electrical equipment where the electrical resistivity of the the extinguishing media is of importance. Agent – FM-2(HFC-227ea) is a clean, gaseous agent containing no particles or oily residues. Design Concentration Requirements.

FM-2leaves no residue or oily deposits on delicate electronic equipment, and can be removed from the protected space by ventilation. For speed in suppressing fires, reducing damages, saving on floor space and allowing visibility, Fike is the clear choice. And it discharges in seconds or less, extinguishing a fire quickly and effectively. The conversion factor is based on extinguishing concentration and ambient room temperature. It takes into account length of pipe, discharge nozzle orifice size, amount of nitrogen to push the gas, etc.

FM-2Typical Sigma System Components GENERAL INFORMATION AND SAFETY PRECAUTIONS 1. GENERAL The Chemetron Sigma series systems are automatic fire s uppression systems. The total terminal pressure (PSI) is the sum of the static pressure form equation (2) and the velocity head pressure calculated from equation (3). The calculation of the pipeline pressure-density relationship for nitrogen superpressurized FM-2is a bit more complicated due to the fact that the nitrogen does dissolve in the FM-200. After receiving the fire signal, FM 2is discharged totally from the cylinders within seconds to fill up the space uniformly at the design concentration to extinguish the fire. It is a room, where according to the MSDS sheets provided to us, has the worst hazard being Diesel Fuel to suppress (engine room).

I have a room protected by FM2, since this is a clean agent and not harmful to the health is it really need to provide ventilation after the discharge, because we are mandate to provide ventilation and compute for the time needed to exhaust the discharge agent. Heptafluoropropane, more commonly known as FM-200. FM-2(3-heptafluoropropane, CF3CHFCF3) is a colorless odorless gas, low in toxicity, electrically non-conductive, leaves no residue, and is an extremely effective fire suppression agent. The condenser removes heat, cooling the gas nearly to ambient, causing most FM-2to condense. A safety relief valve, SRV, is provided to protect the condenser.

Nitrogen and FM-2gas are drawn off at the separator to waste through a back pressure regulator, BPR. SYSTEM DESCRIPTION AND OPERATION 1. The system shall be total flooding FM-2extinguishing system designed to provide a uniform concentration of , at normal average ambient temperature, minimum of FM-200. You will not find a definite how to or how quick. Each situation is different.

As cdafd said calculate your system for a number of air changes per minute or hour that you can live with. Once it goes off, you have other problems to deal with. Typically AC systems use return air from the space and therefore will not help ventilate the area.

VdS calculation software for gas extinguishing systems. For the intended purpose of the calculation programs it is implied that the user of the calculation program possess the necessary knowledge of gas extinguishing systems and of the state of the art of the field of gas extinguishing systems and that the user creates system layouts which represent this knowledge.
