Smoke detector for event classification and methods of making and using same

摘要

Various arrangements for operating a hazard detector are presented. A smoke concentration may be measured using a sensor of the hazard detector. A carbon dioxide concentration may be measured using a carbon dioxide sensor of the hazard detector. The measured smoke concentration may be analyzed in combination with the measured carbon dioxide concentration to determine whether a heads-up alert or warning alarm is to be output. The heads-up alert or the warning alarm may be output based on analyzing the measured smoke concentration in combination with the measured carbon dioxide concentration.
