The invention discloses an optical
smoke-sensing detection test device and a test method thereof, belonging to the technical field of
fire detection. The invention also provides an optical
smoke-sensing detection test device with complete functions and the test method thereof. The optical
smoke-sensing detection test device can exactly measure five types of typical smoke of different
wavelength spectrums on different grain sizes, different colors and different temperatures, an optical scattering smoke-sensing angle is 6-354 degrees, and the smoke-sensing characteristics and a quantization rule of a space with the size of S phi 10-160mm are detected under the condition of keeping a basic constant condition, and reliable design basis and
technical support are provided for a point-type photoelectric smoke-sensing
fire detector with excellent development performances. The optical smoke-sensing detection test device disclosed by the invention comprises an optical smoke-sensing measurement room, a controller, a smoke generator and a
centrifugal fan, wherein an outlet of the smoke generator is connected with an inlet of the optical smoke-sensing measurement room through a smoke guide and control
pipe, an outlet of the optical smoke-sensing measurement room is connected with an inlet of the smoke generator through the smoke guide and control
pipe, and the central fan is connected with the smoke generator.
