FM200 Pipeline System Release Time and Delay Mechanism

What is the release time for the FM200 pipeline network?

  The fire extinguishing agent release time for the FM200 pipe network system is typically controlled within ≤ 10 seconds. 
  Protective areas such as communication rooms and computer rooms: The design discharge time should not exceed 8 seconds. 
  Other protection zones (such as the power distribution room, archives, etc.): The design discharge time should not exceed 10 seconds.

II. Why is this time period specified?

To ensure rapid establishment of the fire suppression concentration
  FM200 is a total flooding gas fire suppression system. It requires the establishment of a sufficient fire suppression concentration (typically 8%-10%) within the protected area at the early stage of the fire to extinguish the fire. If the discharge time is too long, the fire may have already spread and expanded, and the fire suppression effect will be greatly reduced. 

Prevent the risk of fire reignition
  The rapid spray can enable the fire extinguishing agent to quickly cover the fire source at the early stage of the fire, effectively suppressing the combustion chain reaction and preventing the fire from reigniting. 

Reduce the hazards of thermal decomposition products
  When FM200 is exposed to high-temperature flames, it will decompose and produce a small amount of hydrogen fluoride gas. The shorter the spray duration, the shorter the contact time between the fire extinguishing agent and the flame, and the lower the amount of decomposition products generated, resulting in a smaller potential impact on equipment and personnel. 

International standard collaboration
  The NFPA 2001 (Standard for Clean Gas Fire Extinguishing Systems of the American Fire Protection Association) and ISO 14520 and other international standards all have similar regulations regarding the discharge time, ensuring the international universality of the system design.

III. Is there a delay in release time? Why is there a delay?

Yes, the FM200 pipeline system has a delay release time before startup, usually ranging from 0 to 60 seconds (adjustable).
