Introduction
This alarm detects carbon monoxide using an electrochemical cell. Many times throughout this User Guide,
we will refer to Carbon Monoxide as “CO.”
Ten (10) years after the unit was installed, this unit will automatically alert you that it is time to replace the unit.
This is called “End of Unit Life” mode. See Troubleshooting Guide. To help track the life of your alarm, write the
installation date in the space provided on the side of the alarm. A label has been provided that has important
information on what to do in case of a CO alarm. Place the label at eye level on a wall near the alarm after it is
mounted.
