What is an FM-200 fire suppression system?
FM-200™ is a colorless, compressed liquefied gas used to extinguish fires and is a popular replacement for Halon fire suppression systems. FM-200™ fire suppression systems are pressurized with nitrogen, waterless, and upon activation, FM-200™ discharges as a gas to suppress the fire.
What is sprinkler k-factor?
In fire protection engineering, the K-factor formula is used to calculate the discharge rate from a nozzle. Spray Nozzles can be fire sprinklers or water mist nozzles, hose reel nozzles, water monitors and deluge fire system nozzles.
How do I choose sprinkler k-factor?
K-Factor formula for fire sprinklers
- Q = AV.
- Q = A√(2gh)
- q = kp0.5
- k = q / p0.5
- p = ( q / k )2
- for metric calculations: p = pressure in bar. q = flow in litre per minute. k = discharge constant Lpm/bar0.5
- and for imperial calculation: p = pressure in psi. q = flow in gpm. k = discharge constant gpm/psi0.5
What is K value in sprinkler?
The k-factor for a fire sprinkler is the discharge coefficient, or in normal human terms just relates to the amount of water that is permitted through the sprinkler. The k-factor is dependent upon the orifice diameter of the sprinkler – a low k-factor (such as K2.
What caused the FM200 system to discharge?
On Tuesday 3rd July, we experienced a component failure on a single FM200 cylinder that caused it to release its fire supressing gas and subsequently triggered an accidental discharge of the entire FM200 system.
What is FM200 and how does it work?
FM200 is designed for data centres and means in the event of a fire occurring, it is extinguished extremely quickly – all without interruption to your services and no effect on your equipment. An important component of the overall fire safety systems in a data centre is fire detection.
What is FM 200 fire suppressant?
It is an odorless, colorless, liquefied compressed gas which is discharged into the risk within 10 seconds and suppresses the fire immediately. FM 200 fire suppression is used in medical inhalers and found as an active compound. This fire suppressant can be safely used where people are present.
What is the typical concentration of an FM 200 system?
The typical concentration of an FM 200 system is about 7.9% to 8.5%. This concentration is determined by risk that is being protected and by Orginal Equipment Manufacturers or ISO standards for fire suppression systems. For normally occupied spaces FM 200 Fire suppression is a suitable agent.
