Abstract

Le présente addition a pour objet des modifications ayant pour but d'améliorer le fonctionnement du dispositif objet du brevet principal. Le dispositif s'adapte à l'utilisation de détecteurs autocontrôlés ou auto-protégés. On peut obtenir le verrouillage de l'alarme par l'absence de réception des impulsions de contrôle. On peut obtenir le déclenchement de l'alarme, en utilisant une liaison sans fil, par l'éloignement entre l'émetteur et le récepteur. Le dispositif est utilisable dans les systèmes de surveillance, de controle et de détection.
