Abstract:
An air condition detector housing adapted to contain a sensor of ambient air and an alarm circuit, said housing comprising:a front portion including a front portion side wall extending peripherally thereabout, said front portion side wall having at least one segment having a concave configuration for collecting a volume of air; a rear portion releasably coupled to said front portion and defining an interior space therebetween for retaining the air sensor and alarm circuit, said rear portion having an inner surface; a labyrinth integrally connected to said inner surface of said rear portion and adapted to communicate said volume of air to the air sensor; said rear portion including a continuously extending peripheral side wall defining a plurality of spaced apart slots, at least a portion of said side wall having a concave configuration for aerodynamically funneling and accelerating said volume of air through said slots; wherein said rear portion includes a circumference greater than a circumference of said labyrinth; wherein said rear portion and said labyrinth include a black coating such tat said rear portion and said labyrinth inhibit the reflection of light within said interior space; wherein said labyrinth includes a plurality of spaced apart upstanding walls extending radially about an imaginary axis, each wall having a slightly arcuate configuration for funneling the ambient air toward the air sensor; and wherein said front and rear portions include a generally triangular configuration.
