# Direct Release Systems

Our direct release systems utilize heat and flame sensitive Firetrace Detection Tubing as a fire detection device and for the delivery of the suppressant agent.

## Here’s how they work:

1. During a fire, the portion of the tube nearest the point where the most heat is detected ruptures, forming a spray nozzle.
2. The pressure decreases as the tubing releases [fire suppression chemical](https://www.firetrace.in/fire-suppression-chemicals?hsLang=en) from the cylinder through the spray nozzle (burst hole) to effectively suppress the fire.
3. A direct release system can be installed to protect multiple enclosures using a single cylinder by routing additional tubing to each enclosed space.

We recommend direct release systems for protection of [electrical cabinets.](https://www.firetrace.in/electrical-fire-suppression?hsLang=en) For protection of vehicles or CNC machines, we recommend indirect release systems.
