Abstract
A device and method for manufacturing an integrated smoke cell are presented. The smoke cell includes an integral housing with a ceiling portion and a smoke permeable wall forming a chamber when mounted on a printed circuit board. An emitter and detector are mounted above apertures in the chamber ceiling so the emitter and detector are mounted substantially outside the chamber while detecting smoke present within the chamber without blocking ingress of smoke through the chamber wall.
