Abstract

La présente invention concerne un ensemble de détection de pêne dormant qui comprend une batterie de mise sous tension utilisé pour détecter une position d'un pêne dormant de porte. L'ensemble de détection de pêne dormant comprend également un capteur de type interrupteur poussoir qui génère un premier signal de sortie et un capteur de type proximité optique qui génère un second signal de sortie, chacun indiquant si le pêne dormant est dans une position verrouillée ou dans une position déverrouillée. Un détecteur d'erreurs réagit aux premier et second signaux de sortie pour détecter la présence d'une erreur lorsque les premier et second signaux de sortie sont incompatibles l'un avec l'autre. Chaque capteur réagit à un signal périodique permettant de réduire la consommation de courant provenant de la batterie au cours d'une partie d'une période du signal périodique lorsque la détection est désactivée.
