Smoke Alarm Nuisance Source Characterization - Phase 2

During the revision cycle for the 2010 edition of NFPA 72, National Fire Alarm and Signaling Code, the Technical Committee on Single- and Multiple-Station Alarms and Household Fire Alarm Systems (SIG-HOU) added new smoke detection placement requirements. The new requirements intended to reduce nuisance alarms from smoke alarms and detectors installed close to stationary cooking appliances. During the development of the 2013 edition of NFPA 72 the SIG-HOU Technical Committee added new provisions to Chapter 29 to further reduce nuisance alarms. Based on current available data, nuisance sources can be categorized by particle size into small, medium and large particle sources. This Phase II project will collect and analyze data that may be used to develop replicable UL 217/268 test protocols so that products can be listed to comply with resistance to cooking sources and other identifiable nuisance sources, specifically steam/water mist at a minimum.

The project goal is to characterize common nuisance sources for the development of new performance test protocols in ANSI/UL 217 and ANSI/UL 268 product standards in order to meet the NFPA 72-2013 requirements intended to reduce nuisance alarms.
