- Abstract
- 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.
