Abstract
Disclosed is a fire and explosion detection system wherein long wavelength radiant energy responsive signals are processed in one channel and compared to short wavelength radiant energy responsive signals which are processed in a second channel. At least one of the channels is responsive to a wavelength where at least one of the combustion products of the fire or explosion exhibits a strong absorption band in the atmosphere. When the signals from the two channels are coincident in response to a fire or explosion of a predetermined threshold magnitude, an output fire suppression signal is generated.
