Evaluation of the Suitability of CO Measurement for Fire Detection in Space

Methods of fire detection for space application are reviewed and compared. Arguments are given in favour of a decentralized, combined particulate and gas measurement system with highly sensitive, selective and miniaturized sensor elements. For the COLUMBUS pressurized modules this leads to a new baseline concept which now includes ionization chamber and light scattering smoke detectors in the return ducts as well as CO sensors on rack level.
