Here’s how they work:

  1. Once the tubing detects the fire, it ruptures, resulting in a drop of pressure causing the indirect valve to activate. The valve diverts flow from the detection tube to the larger outlet ports.
  2. When the fire suppression system kicks in, a suppressing agent is discharged from the cylinder through the diffuser nozzles, flooding the area while effectively suppressing the fire quickly and thoroughly.
  3. An indirect release system is typically used in larger areas that require a high volume of extinguishing agents to suppress the fire effectively.

Both direct and indirect systems are available in low and high-pressure functionality for areas of any size. A fire suppression specialist can help determine which system is right for your application
