FIELD: fire-fighting equipment.
SUBSTANCE: invention relates to fire-fighting equipment, in particular to stands for examination and control of fire detectors of flame. Test bench for analysing the effect of smoke on the sensitivity of fire detectors comprises a measurement chamber, in the side wall of which there is a germanium window, a gas burner as a source of infrared radiation, a gas analyser of CO and CO2 gases, a smoke generation chamber connected to the measurement chamber by the lower sleeve, an upper sleeve having a passage from above into the measurement chamber, and an additional sleeve connecting the upper and lower sleeves.
EFFECT: high accuracy of controlling intensity of infrared radiation and smoke in the measurement chamber when testing fire detectors.
