Firetrace International’s FIRETRACE systems provide stand-alone automatic fire detection and suppression for bus and coach engine compartments, generators, electrical systems and heaters. The systems includes an extinguishing agent cylinder — which is usually mounted in a convenient location in or near the engine compartment — attached to a specially developed leak-resistant polymer tubing, via a custom-engineered valve. This proprietary detection tubing is a linear pneumatic heat and flame detector that was specially developed to deliver the desired temperature-sensitive detection and delivery characteristics in even the harshest of environments. Once a fire is detected, the tubing ruptures and automatically releases the suppression agent, extinguishing the fire.
