Abstract:
A multi-sensor fire detector includes first and second flame sensors which are coupled to an external environment by a rigid, tapered, optical coupling element. An external end of the coupling element has a cured hemispherical shape with a viewing angle approaching one hundred eighty degrees. Processing and control circuits coupled to the sensors make a determination as to the presence of a fire condition.
