Kidde KN-COPP-3-RC manual Display Readings, AC and DC Start Up, Alarm and Error Operation

Display Readings

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.
