Title
(EN) FIRE DETECTION SYSTEM COMPRISING AN ALARM CONTROL PANEL RECEIVING AN ANALOG SIGNAL
(FR) SYSTEME DE DETECTION D'INCENDIE COMPORTANT UNE CENTRALE D'ALARME RECEVANT UN SIGNAL ANALOGIQUE
Abstract
(EN)
Fire detection device (1, 2, 5) comprising at least one fire detector (1) that supplies an electric current to an alarm control panel (5) provided with a central processing unit (10) for alerting it to the presence of a fire. The central processing unit is designed to measure the value of this current at regular time intervals, setting off an alarm reaction if the difference between the measured value and a reference value exceeds a predetermined threshold. The reference value is a value of the current at the start or on resetting of the central processing unit.
(FR)
L'invention concerne un dispositif de détection d'incendie (1, 2, 5) comportant au moins un détecteur d'incendie (1) qui transmet un courant électrique à une centrale d'alarme (5) dotée d'une unité centrale (10) pour lui signaler ou non l'existence d'un incendie, l'unité centrale étant conçue pour mesurer la valeur de ce courant à intervalles de temps réguliers et pour déclencher une réaction d'alarme si la différence entre cette valeur mesurée et une valeur de référence est supérieure à un seuil prédéterminé. La valeur de référence est une valeur du courant à la mise en marche ou à la réinitialisation de l'unité centrale.
