Abstract
L'invention concerne la transmission de signaux d'alarme sur le réseau téléphonique public. Un émetteur 10, associé à un poste d'abonné, transmet une information d'alarme par la ligne téléphonique 12, vers un processeur local 16. Cette information est transmise sous la forme d'un signal porteur modulé en amplitude par un signal audiofréquence. Plusieurs processeurs locaux 16 sont raccordés à un processeur central 20 qui attaque les points d'affichage d'alarme 21. Application à la protection contre le vol ou l'incendie.
