Abstract

En fremgangsmåte for deteksjon av røkdetektoralarmer omfatter analysering av minst to parametere av omgivelseslyd over en tidsperiode for å detektere et tidsmønster av alarmen. I en utførelse tas en rekke sampler over en tidsperiode som er tilstrekkelig lang til å omfatte minst en fullstendig periode av et gjentatt opptredende lydmønster, og de to parametere er frekvens og amplitude av den høyeste lyd i hvert sampel. Den algoritmiske analyse kan utløses av en deteksjonsalgoritme som utnytter en lavere effektmengde enn den algoritmiske analyse. I andre utførelser er deteksjonsinnretningen innlemmet i en konvensjonell røkdetektor som vil detektere både røk og en alarm fra en annen detektor. I en annen utførelse omfatter en røkdetektor en transceiver for å utsende et aktiveringssignal til nærliggende røkdetektorer når en brann detekteres, og for å motta et aktiveringssignal fra nærliggende detektorer.
