01
The ISS smoke detector is a 2-pass IR laser-diode forward-scattering detector with a minimum reported sensitivity of 0.3 microns.
Detection · p. 4 · AI confidence 95% · Reported · Pending
“ISS detector: sensitive > 0.5 micron • 2 - pass IR laser - diode forward - scattering detector (30 degrees) minimum reported sensitivity is 0.3 μm .”
-
02
The STS detector is a dual-chamber ionization detector with an inertial separator that rejects particles larger than 1-2 microns.
Detection · p. 4 · AI confidence 95% · Reported · Pending
“STS Detector: sensitive < 1 micron • dual - chamber ionization with inertial separator which rejects particles larger than 1 - 2 microns.”

03
Silicone rubber smoke produced a strong signal on both the ISS and STS smoke detectors.
Detection · p. 14 · AI confidence 90% · Extracted · Pending
“Silicone Rubber: Note strong signal on both smoke detectors”
-
04
Teflon smoke produced a weak signal on the ISS scattering detector but a strong signal on the STS ionization detector.
Detection · p. 14 · AI confidence 90% · Extracted · Pending
“Teflon: Note weak scattering (ISS) detector signal but ionization (STS) is still strong”

05
Aging of smoke aerosols resulted in a decrease in number concentration and an increase in number mean diameter, consistent with theory for number count and D_avm but not for geometric standard deviation.
Other · p. 32 · AI confidence 90% · Extracted · Pending
“Aging results consistent with theory for number count and D avm but not for σ g”

06
Size selective smoke detection using multiple moments or particle classification is recommended to improve reliability and false alarm rejection.
Detection · p. 33 · AI confidence 90% · Extracted · Pending
“Size selective smoke detection will improve reliability and false alarm rejection. Either by classifying the particles or by measuring multiple moments.”
