Originally designed for race cars, the Fire Fight Automatic-Release Fire Extinguisher can be mounted in an engine compartment or anywhere there's a fire potential. It uses heat-activated thermal links, which are set off at 165 or 286 degrees F, depending on the application. Available in a variety of sizes, the rechargeable extinguisher contains either, Halon, AFFF, or FE36 as the fire suppressant. The manufacturer provides ready-to-install or custom-designed mounting systems.
