The evaluation of a near-infrared fire detector using
standard test fires is presented. The spectral
radiation intensities incident on the fire detector are
continuously measured at two near-infrared wavelengths
(900 and 1000 nm), and a time series of apparent source
temperatures is obtained from these measurements. The
power spectral density and the probability density
function of the apparent source temperatures are
sufficient to determine the presence of a fire in the
vicinity of the detector. The detector can also
indicate the presence of a fire in an adjoining room
from the radiation which is incident on it due to
reflections from common building materials.
