Early fire detection sensor

Emerging fires on manned space stations or in aircrafts could lead to hazardous situations for the passengers and the crew on board. Furthermore complex and valuable spacecraft or aircraft equipment needs to be protected for safety reasons.

Today’s fire detection systems are providing reliable fire alarm information. But for new concepts like the long haul operations of aircrafts or the large-scale space stations new approaches are needed. Reasonable features of such fire detection modules are further reduction of the false alarm probability, self-test and pre-warning capabilities. This article presents recent results on possible pre-warning strategies. Today’s fire detection modules rely on stray light detection. Soot particles arisen from burning fires can be detected. This effect leads to a reliable fire-warning signal but a prediction of fire events cannot be given.

This new concept is using a signature analysis of possible fire precursors and the metabolism oriented gases. Fire precursors are gaseous products emerging from incomplete combustion e.g. hydrogen, hydrocarbons and carbon monoxide. Typical metabolism oriented gases are carbon dioxide and water vapour. An infrared system was built up in order to measure the above mentioned gases and to verify the measurement strategy.
