Firetrace Indirect Release Systems

How it works: An indirect release is when the tube acts as a detection device and, through the pressure change, tells the system to discharge the agent through other pipes and nozzles.

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.

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.

An indirect release system is typically used in larger areas that require a high volume of extinguishing agents to suppress the fire effectively.

Common applications: Indirect release systems are commonly used for vehicles and in CNC machines.

Key benefits: Firetrace Indirect Release Systems have been independently tested and evaluated by the leading product performance testing agencies. They are UL Listed and FM Approved. Third party testing ensures that products consistently perform as expected and can tolerate environmental challenges like temperature change. Local and national fire codes, including those published by the National Fire Protection Association (NFPA) often recommend UL or FM approved systems.

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