Abstract
CE DISPOSITIF D'ALARME, QUI EST DESTINE NOTAMMENT A DES VEHICULES A MOTEUR ET COMPORTE AU MOINS UN AVERTISSEUR ACOUSTIQUE OU OPTIQUE, AU MOINS UN DETECTEUR, ET UN SYSTEME DE COMMANDE REAGISSANT AUX SIGNAUX DE DECLENCHEMENT D'ALARME POUR ACTIONNER L'AVERTISSEUR, EST CARACTERISE EN CE QU'UN ETAGE DE COMMANDE 13 RELIE A UN INTERRUPTEUR 15 ENVOIE, LORSQU'ON ACTIONNE CE DERNIER, UN SIGNAL DE DECLENCHEMENT D'ALARME A UN CIRCUIT 5, 7 D'ACTIONNEMENT DE L'AVERTISSEUR 11, ET EN CE QUE LE SYSTEME DE COMMANDE, A LA SUITE DE SIGNAUX DE DECLENCHEMENT D'ALARME ENVOYES PAR L'ETAGE DE COMMANDE 13, NEUTRALISE L'AVERTISSEUR ET, PAR L'INTERMEDIAIRE DU CIRCUIT D'ACTIONNEMENT, ACTIONNE UN APPAREIL DE CONTROLE ACOUSTIQUE ETOU OPTIQUE 35, 37. ON PEUT AINSI CONTROLER LE BON ETAT DE FONCTION DES ELEMENTS DU DISPOSITIF COMPRIS ENTRE LE DETECTEUR ET L'AVERTISSEUR.THIS ALARM DEVICE, WHICH IS INTENDED IN PARTICULAR FOR MOTOR VEHICLES AND INCLUDES AT LEAST ONE ACOUSTICAL OR OPTICAL ALARM, AT LEAST ONE DETECTOR, AND A CONTROL SYSTEM RESPONDING TO ALARM RELEASE SIGNALS TO ACTIVATING THE ALARM, IS CHARACTERIZED IN THAT A CONTROL STAGE 13 CONNECTED TO A SWITCH 15 SENT, WHEN THE LATTER IS ACTED, AN ALARM TRIP SIGNAL TO A CIRCUIT 5, 7 FOR ACTUATION OF THE ALARM 11, AND IN THAT THE CONTROL SYSTEM, FOLLOWING AN ALARM TRIGGER SIGNALS SENT BY THE CONTROL STAGE 13, NEUTRALIZES THE ALARM AND, THROUGH THE ACTUATION CIRCUIT, ACTIVATES AN ACOUSTIC AND OR OPTICAL CONTROL DEVICE 35, 37. THE GOOD CONDITION OF OPERATION OF THE ELEMENTS OF THE DEVICE INCLUDED BETWEEN THE DETECTOR AND THE ALARM CAN BE CHECKED.
