Title (EN) ALARM SYSTEM AUDIO INTERFACE TAMPER AND STATE DETECTION
(FR) SYSTÈME D'ALARME: DÉTECTION D'INTERVENTION ILLICITE ET D'ÉTAT D'INTERFACE AUDIO
Abstract: front page image
(EN)An alarm system comprises: an audio interface comprising: a microphone; a state sensor for sensing a state at the audio interface; a signal generator for generating an inaudible state signal indicative of the state; a multiplexer for combining an audio signal from the microphone and the state signal; a control panel for monitoring sensed conditions at the audio interface; a conductor interconnecting the audio interface to the control panel carrying audio signal and the state signal as combined from the audio interface to the control panel.
(FR)L'invention porte sur un système d'alarme à interface audio comportant : un microphone; un détecteur d'état au niveau de l'interface audio; un générateur de signal émettant un signal d'état inaudible indicatif de l'état; un multiplexer combinant un signal audio provenant du microphone et le signal d'état; un panneau de commande pour surveillance des conditions détectées au niveau de l'interface audio; un conducteur interconnectant l'interface audio au panneau de commande acheminant un signal audio et le signal d'état combiné de l'interface audio vers le panneau de commande.
