Abstract
A debris blocking device that may prevent grease and particular buildup inside the protective piping of a typical fusible link fire detection system. The debris blocking device has a shield with two surfaces. The one surface engages a protected object, while the other surface forms an area of the shield. The debris blocking device has an opening disposed within the area of the shield. The debris blocking device may engage a length of conduit, or piping that has an inside and an outside surface, and an open end. One surface of the debris blocking engages the inside surface of the open end of the conduit or pipe. This surface of the debris blocking device may also contain the opening that is capable of admitting an elongated component.
