The Spectrex AFES (Automatic Fire/Explosion Extinguishing System) protects against combat-initiated and slow-growth fires featuring high-speed optical detection in less than 3 milliseconds, explosion suppression within 150 milliseconds, multiple ultra-fast extinguishing agent discharge and dispersion. The system is capable of detecting and suppressing all possible types of fires, i.e., small or large, slow or rapidly growing, limited in area or widely spread, as well as fuel explosions which are likely to occur during combat or training service of these military vehicles.
