CO Alarms are not a substitute for a smoke alarm. Although fire is a
source of carbon monoxide, this CO Alarm does not sense smoke or
fire. This CO Alarm senses CO that may be escaping unnoticed from
malfunctioning furnaces, appliances, or other sources. Early warning of
fire requires the installation of smoke alarms.
