Smart Hazard Detector Providing Follow Up Communications to Detection Events

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

A hazard detector comprising:

• a hazard sensor that measures amounts of a hazardous condition present in an ambient environment of the hazard detector;
• an output component that outputs information;
• and
• a processing system that comprises one or more processors, the processing system being in communication with the output component and the hazard sensor, the processing system being configured to:
• receive a first measurement of a first amount of the hazardous condition present in an ambient environment of the hazard detector from the hazard sensor;
• set a mode of the hazard detector to a pre-alarm or alarm state based on the first measurement;
• receive a second measurement of a second amount of the hazardous condition present in the ambient environment of the hazard detector from the hazard sensor;
• and
• determine, based on the second measurement, to set the mode to a non-alarm state.

A non-transitory processor-readable medium for a hazard detector, comprising processor-readable instructions configured to cause one or more processors of the hazard detector to:

• receive a first measurement of a first amount of the hazardous condition present in an ambient environment of the hazard detector from the hazard sensor;
• set a mode of the hazard detector to a pre-alarm or alarm state based on the first measurement;
• receive a second measurement of a second amount of the hazardous condition present in the ambient environment of the hazard detector from the hazard sensor;
• determine, based on the second measurement, to set the mode to a non-alarm state;
• and
• in response to determining at least partially based on the second measurement to set the mode of the hazard detector to the non-alarm state, cause an indication that the hazardous condition has eased to be output by the hazard detector.
