FIRE DETECTOR COMPRISING AN ANALOG SENSOR

摘要

Fire detector (1) comprising a fire sensor (7) that supplies an analog electric signal to a central processing unit (6), alerting it to the presence of a fire. The central processing unit is designed to measure the value of this signal at regular time intervals and to set off an alarm reaction if the difference between the measured value and a reference value exceeds a predetermined threshold. The reference value taken into account for each new measured signal value depends upon at least some of the signal values measured beforehand.
