One of the leading hazards affecting everyday life around the world might be smoke, fire and flame. Smoke detectors are widely used for detecting fire and raised alarm saving people life. However, faulty smoke detectors cause false alarm resulting from smoke and fire. In addition, smoke detector fails to detect fires in large spaces including outdoor spaces, auditorium, and warehouses which are...

In this paper we present a prototype of a Strip Resistive Thick GEM (S-RETGEM) photosensitive gaseous detector filled with Ne and ethylferrocene (EF) vapours at a total pressure of 1 atm for an early forest fire detection system. Tests show that it is one hundred times more sensitive than the best commercial ultraviolet (UV) flame detectors; and therefore, it is able to reliably detect a flame ...

Laboratory experiments were conducted to determine the responses of a prototype smoke detector and a commercially available photoelectric smoke detector to smoke particles generated from various combustion sources. The prototype smoke detector combines optical scattering measurements with ionization chamber measurements in order to reduce/eliminate nuisance alarms due to the presence of airborn...
