Description

FIG. 1 is a perspective view of a heat detector illustrating one embodiment of our new design;

FIG. 2 is a top view of the heat detector of FIG. 1;

FIG. 3 is a side view of the heat detector of FIG. 1, the other side view being substantially a mirror image thereof;

FIG. 4 is a perspective view of a heat detector embodying an alternative embodiment of our new design;

FIG. 5 is a top view of the heat detector of FIG. 4; and,

FIG. 6 is a side view of the heat detector of FIG. 4, the other side view being substantially a mirror image thereof.

Front and rear elevations have not been illlustrated as the heat detector is circular such that all side views are substantially the same. The bottoms of the detectors have not been illustrated as they are non-ornamental and not part of the design.
