US Patent 9990842 Learning alarms for nuisance and false alarm reduction

A learning alarm includes a sensor operatively connected to a processor to detect environmental properties and an alarm operatively connected to the processor to provide an alert if the environmental properties are outside an acceptable range. A user interface is operatively connected to the processor to accept user input indicating an alert corresponds to a nuisance condition. A memory is also operatively connected to the processor for storing detected environmental properties corresponding to the nuisance condition. The processor is configured to suppress alerts from the alarm based on detected environmental properties corresponding to the environmental properties of the nuisance condition stored in the memory.
