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) focused renewed attention on nuisance alarms. Based on the information in the NFPA report "Smoke Alarms in U.S. Home Fires" authored by Marty Ahrens, during the development of the 2013 edition of NFPA 72 the SIG-HOU Technical Committee added several new provisions to Chapter 29 to further reduce nuisance alarms.
There was a lack of characterization of common nuisance sources for the development of new performance test protocols. Accordingly, the Foundation initiated a project to work toward characterizing common nuisance sources for the development of new test protocols to meet the NFPA 72 requirements. This Phase 2 project involved collecting data to characterize nuisance sources from cooking and steam/water mist and comparing the nuisance source data to existing fire test data.
Now, the full report from Phase 2, "Smoke Alarm Nuisance Source Characterization: Experimental Results" authored by Joshua B. Dinaburg and Dr. Daniel T. Gottuk, Ph.D. with Jensen Hughes, is available for download.
