NFPA Standard 72

IntheUnitedStatesandCanada,smokedetectorsmustbeinstalledinaccordancewithNationalFireProtectionAssociation

(NFPA)Standard72:NationalFireAlarmandSignalingCode,whichreadsasfollows:

“2‐1.1.1Smokealarmsshallbeinstalledoutsideofeachseparatesleepingareaintheimmediatevicinityofthe

bedroomsandoneachadditionalstoryofthefamilylivingunitincludingbasementsandexcludingcrawlspacesand

unfinishedattics.Innewconstruction,asmokealarmshallbeinstalledineachsleepingroom.

2‐1.1.2Forfamilylivingunitswithoneormoresplitlevels(i.e.,adjacentlevelswithlessthanonefullstoryseparation

betweenlevels),asmokealarmshallsufficeforanadjacentlowerlevel,includingbasements.(Exception:Wherethere

isaninterveningdoorbetweenonelevelandtheadjacentlowerlevel,

asmokealarmshallbeinstalledonthelower

level.)

•Ceilingmountedsmokealarmsshouldbelocatedinthecenteroftheroomorhall,ornotlessthan4inchesfrom

anywall.Whenthealarmismountedonawall,thetopofthealarmshouldbe4to12inchesfromtheceiling.

•Donotinstallsmokealarmswherenormalambienttemperaturesareabove100°F(37.8°C),orbelow40°F(4°C).

circulationwillkeepsmokefromenteringthedetector.

A‐2.5.2.1SmokeDetection‐AreMoreSmokeAlarmsDesirable?Therequirednumberofsmokealarmsmightnot

providereliableearlywarningprotectionforthoseareasseparatedbyadoorfromtheareasprotectedbytherequired

smokealarms.Forthisreason,itisrecommendedthatthere sidentialuserconsidertheuseofadditionalsmokealarms

forthoseareasforincreasedprotection.Theadditionalareasincludethebasement,bedrooms,diningroom,furnace

room,utilityroom,andhallwaysnotprotectedbytherequiredsmokealarms.Theinstallationofsmokealarmsin

kitchens,attics(finishedorunfinished),orgaragesisnotnormallyrecommended,as

theselocationsoccasionally

experienceconditionsthatcanresultinimproperoperationorfalsealarms.”
