FM-approved FireChek thermal shutoffs with resettable memory shape alloy can now be used to automatically shut down a pneumatic control system when a nearby fire occurs, or when the ambient temperature reaches 135, 150, or 165⁰ F. The testability and reset ability of the FireChek separate it from emergency isolation valves that rely on fusible links or plastic burn-through tubing.
