Abstract

L'invention concerne une installation de surveillance d'un espace fini. Cette installation comprend au moins un dispositif 1 sensible aux variations d'au moins un paramètre de l'espace surveillé, ce dispositif 1 émettant un signal à chacune desdites variations, un circuit d'alarme 6, et des moyens pour connecter ce dispositif 1 au circuit d'alarme 6 et comprenant un circuit de temporisation 4 destiné à compter un laps de temps prédéterminé à partir de la réception de chaque signal et à connecter automatiquement le dispositif 1 au circuit d'alarme 6 lorsqu'aucun signal n'est reçu pendant ledit laps de temps déterminé. Application : enclenchement automatique d'une installation de surveillance.
