Abstract | According to one embodiment, a hazard detector may include a back plate and a front casing coupled to the back plate to define a housing having an interior region and an opening through which air flows into the interior region. A circuit board may be coupled to the back plate and have a plurality of components mounted thereon. A smoke chamber may be mid-mounted on the circuit board, mid-mounting being characterized in the smoke chamber extending through a hole formed in the circuit board such that a top surface of the smoke chamber is positioned above a top surface of the circuit board and a bottom surface of the smoke chamber is positioned below a bottom surface of the circuit board, whereby an interior region of the smoke chamber is accessible to smoke from both the top and bottom surfaces of the circuit board.
Selon un mode de réalisation, un détecteur de danger peut comprendre une plaque arrière et un boîtier avant accouplé à la plaque arrière pour définir un logement comportant une région intérieure et une ouverture à travers laquelle un air s'écoule dans la région intérieure. Une carte de circuit peut être accouplée à la plaque arrière et avoir une pluralité de composants montés sur celle-ci. Une chambre de fumée peut être montée à mi-distance sur la carte de circuit, le montage à mi-distance étant caractérisé en ce que la chambre de fumée s'étend à travers un trou formé dans la carte de circuit de sorte qu'une surface supérieure de la chambre de fumée soit positionnée au-dessus d'une surface supérieure de la carte de circuit et qu'une surface inférieure de la chambre de fumée soit positionnée au-dessous d'une surface inférieure de la carte de circuit, moyennant quoi une région intérieure de la chambre de fumée est accessible à la fumée provenant à la fois des surfaces supérieure et inférieure de la carte de circuit. |
