Abstract
L'INVENTION CONCERNE UN DETECTEUR COMPRENANT UNE DOUILLE ET UNE TETE DETECTRICE MUNIE D'UN CIRCUIT ELECTRIQUE. LA DOUILLE COMPORTE UN DISPOSITIF D'ACCOUPLEMENT QUI DELIMITE UNE PARTIE DE COOPERATION ET DESIGNE UNE TETE DETECTRICE QUI PEUT ETRE COUPLEE. LES TETES DETECTRICES ONT DES PARTIES DE COOPERATION DONT LA STRUCTURE EST SPECIFIQUE SI BIEN QUE SEULE UNE TETE D'UN TYPE DETERMINE PEUT COOPERER AVEC LA PARTIE CORRESPONDANTE DE LA DOUILLE. APPLICATION AUX DETECTEURS D'INCENDIE ET DE FUMEES.
