1. A method for detecting that a hazardous condition is easing, the method comprising:

  • measuring, by a hazard detector, a first amount of the hazardous condition present in an ambient environment of the hazard detector;

    setting, by the hazard detector, a mode of the hazard detector to an alarm state based on the measured first amount of the hazardous condition;

    measuring, by the hazard detector, a second amount of the hazardous condition present in the ambient environment of the hazard detector, wherein the second amount is less than the first amount;

    determining, by the hazard detector, at least partially based on the second amount of the hazardous condition present in the ambient environment, to set the mode to a non-alarm state; and

    in response to determining, at least partially based on the second amount of the hazardous condition present in the ambient environment to set the mode of the hazard detector to the non-alarm state from the alarm state, outputting an indication that the hazardous condition has eased, wherein;

    the hazardous condition having eased indicates the hazardous condition in the ambient environment of the hazard detector has decreased in amount.
