ABSTRACT:
A fire detection system contains several detectors connected to a control center, some of which are fitted with at least two sensors for monitoring different fire parameters. Preferably, one sensor is a thermal sensor and another is an optical sensor. An arrangement for processing the sensor signals is located within each of the detectors. It contains a microcontroller for conditioning the sensor signals and for signal processing, with the aim of generating alarm signals. The alarm signals are obtained in a neural network.
