Every line below is in CPSC’s own words, with its source beside it.
What’s wrong with it?
Sensors in these fire detection systems could experience reduced sensitivity to smoke in conditions of high humidity and high temperature. If this occurs, these sensors could delay detecting the presence of smoke in the event of a fire.
