fire safety; fire detection systems; fire detectors
The performance of a fire detection system is determined
as much by its ability to recognize correctly the
non-fire state as to sense the presence of a real fire.
Common fire detectors respond to particulate matter in
the form of smoke from a flaming or smoldering source by
scattering light, absorbing light, or decreasing the
level of ionization. Atmospheric aerosols from non-fire
sources also can cause an ionization or photoelectric
detector to respond. While different manufacturers have
developed means to compensate for background particulate
levels, standard methods to assess how well a particular
detector discriminates background from fire-generated
aerosols do not exist. The purpose of the FE/DE is to
produce an environment representative of what would be
present immediately adjacent to an installed detector.
