Abstract

L'invention concerne un appareil de protection contre les risques d'effraction. Dans ce montage, dans lequel des récepteurs 2, 4 transmettent des signaux SUS , SMW à un détecteur de produit 12 formant mélangeur de signaux reliés par un filtre RC 19 à un détecteur à valeur de suil 11 raccordé au récepteur 2 par un convertisseur fréquence-tension 14, le détecteur Il est conçu de manière que son seuil de détection peut être modifié en fonction de la fréquence du signal de commande Ust qui lui est envoyé et qui est dérivé du signal SUS . Application notamment aux appareils de protection contre des risques d'effraction dans des voitures et des bâtiments.
