Firetrace systems do not require electronic fire detectors. Instead, the system detects fires using specially designed tubing. The tubing is made of a flexible polymer that can be installed anywhere a fire might start. Firetrace tubing can detect both heat and flames. When it detects either, then it bursts open, activating the system.
When the detection tubing bursts, there is a pressure change in the system. This activates a valve, which releases gas or powder stored in the cylinder. Unlike fire extinguishers, Firetrace systems do not require manual operation. However, systems can be manually operated by pushing a button called the manual release.
Firetrace systems contain specialized gas or powder, designed for putting out fires. These are called suppression agents. Suppression agents put out fires by eliminating heat or oxygen or by disrupting chemical reactions. When the system activates, the agent travels from the cylinder to the protected space, either directly through the detection tube or through connected hoses and nozzles.
