1 BRANDSENSOR
1. Brandsensor (1) omfattende: en flerhed af labyrintvægge (13), der er installeret langs en periferisk retning for at omgive et røgdetekteringsrum (A); en lysudsendende enhed (8), der er placeret med henblik på at stråle lys mod røgdetekteringsrummet (A); en lysmodtagende enhed (9), der er placeret i en position, hvor den lysmodtagende enhed (9) ikke direkte modtager lyset udsendt fra den lysudsendende enhed (8); og en varmesensor (3a), hvor røgdetekteringsrummet (A) indbefatter et røgdetekteringsområde (B) defineret af en lysudsendelseszone, der strækker sig fra den lysudsendende enhed (8), og en lysmodtagelseszone, der strækker sig fra den lysmodtagende enhed (9), hvilken brandsensor (1) er konfigureret til at opdage en brand, når den lysmodtagende enhed (9) modtager det spredte lys fra den lysudsendende enhed (8) genereret i røgdetekteringsområdet (B) af røg, der er introduceret i røgdetekteringsrummet (A) gennem åbninger mellem labyrintvæggene (13), hvor et penetrationsområde (C) er dannet af et hus (4, 8b), der udgør den lysudsendende enhed (8) eller den lysmodtagende enhed (9), hvilket penetrationsområde (C) er adskilt fra røgdetekteringsrummet (A), hvilket penetrationsområde (C) strækker sig gennem huset (4, 8b) fra siden af en husmonteringsplade (3), hvorpå huset (4) er monteret mod et måldetekteringsrum, hvilken varmesensor (3a) er indsat i penetrationsområdet (C), kendetegnet ved, at penetrationsområdet (C) er placeret i en lysudsendelsesplatformsdel (8b) til at huse den lysudsendende enhed (8) eller i en lysmodtagelsesplatformsdel (9b) til at huse den lysmodtagende enhed (9).
2. Brandsensor ifølge krav 1, hvor et snævert område (R), der eksisterer mellem den lysudsendende enhed (8) og den lysmodtagende enhed (9) og ikke indbefatter røgdetekteringsområdet (B), er defineret i røgdetekteringsrummet (A),
