Title:StandardizedTestingFire-RelatedResearchforEvaluatingIonizationandPhotoelectricSmokeDetectors
Introduction:
Smokedetectorsarecrucialsafetydevicesusedworldwidetodetectandalertoccupantsofthepresenceofsmokeandpotentialfirehazards.However,notallsmokedetectorsarecreatedequal.Differenttypesofsmokedetectorsutilizedifferentsensingtechnologies,suchasionizationandphotoelectric,whichvaryintheireffectivenessandresponsetimeindifferentfirescenarios.ThispaperaimstodiscussthestandardizedtestingresearchconductedbytheBritishArchitecturalResearchInstitutetoevaluateionizationandphotoelectricsmokedetectorsinfire-relatedcontexts.
