ABSTRACT:
A sensor system for the detection and/or analysis of smoke, gas or the like, comprising a detection means 6 connected to an analyser means 2 via fiber-optic links 3, 11 and 12. The detector 6 determines the presence of smoke, gas or the like, while the analyzer 2 analyzes the composition of the smoke, gas or the like. The exact location and nature of the smoke, gas or fire can therefore be determined with the aid of suitable associated circuitry 9.
