of combustion in order to provide protection for said devices for the detection of products of combustion from physical damage
and/or tampering, such that:
(a) the thin solid fins, plates or blades of the system are formed to fit and connect to the corners, sides, and other interior
surfaces of said guard to within one eighth inch of the ceiling or wall surface to which said guard and said device for the
detection of the products of combustion are attached, and to fit to within one eighth inch of the profile of an external cover
or housing of the device for the detection of the products of combustion;
(b) the thin solid fins, plates, or blades of the system form a series of chambers within the space between the interior surface
of said guard and the exterior surface of the cover or housing of the device for the detection of the products of combustion;
(c) wherein the chambers narrow from the interior surfaces of the corners, sides and/or bottoms of the guard to the exterior
surfaces of the cover or housing of the device for the detection of the products of combustion;
