Every line below is in CPSC’s own words, with its source beside it.
What’s wrong with it?
After alerting consumers to the presence of natural gas or carbon monoxide, the recalled alarm can go into sleep mode when the alert lasts less than four minutes. During this time, the alarms can fail to detect and alert consumers to a new incidence of natural gas or carbon monoxide, posing a risk of carbon monoxide poisoning.
