FIRE DETECTION SYSTEM COMPRISING AN ALARM CONTROL PANEL RECEIVING AN ANALOG SIGNAL

摘要

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.
