The Firetrace Indirect Fire Protection System uses the Firetrace tubing as a "Fire Detection" and "System Activation" device, not as the discharge tube. Once the tubing senses the fire, the tube then ruptures and the resulting drop in pressure causes the indirect valve to activate. Carbon dioxide (CO2 ) is then discharged from the cylinder through a fixed piping network and out of the diffuser nozzles, flooding the area in extinguishant and suppressing the fire quickly and thoroughly.
