Abstract

A találmány tárgya extinkció elvén alapuló, optikai füstjelző, amelyfényforrással (L1) és egy-egy vevőt (E1, E2) tartalmazó mérési ésreferenciaszakasszal (M1, R2) ellátott optikai hidat, valamintkiértékelő egységet (3) tartalmaz. A találmány szerint az optikaifüstjelző második fényforrással (L2) is el van tátva, ahol mindegyikfényforrás (L1, L2) felől egy kívülről nyitott mérési szakasz az egyikvevőhöz és egy kívülről lezárt referenciaszakasz a másik vevőhöz vanvezetve, ahol mindegyik vevő az egyik fényforrás számára mérésivevőként, a másik fényforrás számára pedig referenciavevőként, ésfordítva, hatóan van elrendezve. A találmány tárgya továbbbá afüstjelző alkalmazása fürdőszobákban és/vagy azokkal összekapcsolthelységekben vagy repülőgépek csomagtereiben. ÓThe subject of the invention is an optical smoke detector based on the principle of extinction, which includes an optical bridge equipped with a light source (L1) and a measuring and reference section (M1, R2) containing a receiver (E1, E2) and an evaluation unit (3). According to the invention, the optical smoke detector is also provided with a second light source (L2), where from each light source (L1, L2) an externally open measurement section is led to one receiver and an externally closed reference section is led to the other receiver, where each receiver acts as a measurement receiver for one of the light sources, the and it is effectively arranged as a reference receiver for another light source and vice versa. The subject of the invention is also the use of smoke detectors in bathrooms and/or in areas connected thereto or in aircraft luggage compartments. HE
