Results of Full-Scale Fire Tests with Photoelectric Smoke Detectors
In February 1974, a series of full-scale fire tests were conducted to determine whether photoelectric-type smoke detectors could respond to the same types of fires used to assess the performance of ionization-type smoke detectors. The types of fires employed in the tests are the same as those outlined in Underwriters' Laboratories, Inc., Standard No. 167. In addition to the UL-167 standard fires, fires involving polyurethane (flaming mode) and cotton (smoldering mode) were added to the test series. One detector, utilizing a Taguchi gas sensor (TGS), was included in the test series for evaluation purposes. The test results indicated that the better photoelectric smoke detectors, i.e., those having little obstruction to slow-moving smoke can, in general, detect the same test fires as the ionization chamber smoke detectors in approximately the same time scale. For the smoldering cotton fire, the photoelectric detectors were significantly faster than the ionization chamber detectors. The TGS fire detector was unable to detect most of the test fires.
