Abstract

The invention relates to a smoke detector comprising a detection chamber in which are positioned an emitter device which emits electromagnetic radiation (typically infrared type) and a receiver device which receives it. The smoke detector also comprises a main printed circuit board electrically connected to both the emitter device and the receiver device. The receiver device and/or the emitter device are located on dedicated printed circuit boards which are electrically connected, possibly through connectors, to the main printed circuit board.
