Abstract

L'invention concerne un dispositif pour la surveillance des locaux blindés et pour la production d'un signal d'alarme lorsqu'un essai d'effraction est entrepris. Ce dispositif comprend un transducteur acoustique-électrique 1, dans lequel est monté un détecteur de température 31 et qui est relié à deux chemins de signal A-B, dont l'un se compose d'un amplificateur, d'un détecteur de seuil, d'un élément intégrateur et d'un étage de sortie pour la production du signal d'alarme en répondant aux faibles signaux d'une certaine durée tandis que l'autre chemin B, construit d'une façon semblable, répond aux signaux de courte durée à une grande amplitude qui proviennent d'une explosion. Le détecteur de température est relié à l'étage de sortie en produisant un signal d'alarme lorsque le transducteur atteint une température limite.The invention relates to a device for the surveillance of armored premises and for producing an alarm signal when a break-in test is undertaken. This device comprises an acoustic-electric transducer 1, in which is mounted a temperature detector 31 and which is connected to two signal paths AB, one of which consists of an amplifier, a threshold detector, an integrating element and an output stage for producing the alarm signal by responding to weak signals of a certain duration while the other path B, constructed in a similar fashion, responds to signals of short duration at a large amplitude that come from an explosion. The temperature sensor is connected to the output stage producing an alarm signal when the transducer reaches a limit temperature.
