Your new Carrier carbon monoxide alarm is a sophisticated electronic
device – yet very simple to understand. Basically, the unit will display
a “0” if it senses 30 PPM of CO or less and if you have a good backup
battery pack installed.
If it senses carbon monoxide, it will display a reading so you can see
if you have a non-threatening or emergency situation.
However, if the backup battery pack is low or missing, or if the unit
malfunctions, it will display other readings (and alarm differently) to
alert you that something is wrong with the alarm.
Please familiarize yourself and other family members to the difference
between a CO reading and a reading signifying a problem with the
alarm itself.
