Introduction
This alarm detects products of combustion using a photoelectric sensor and carbon monoxide (on
combination smoke/CO models only) 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, powered up, and tested, 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 identify the date to replace the unit, a label has been affixed to the side of the alarm. Write the
“Install date” in the space provided, and then write in the “Replace by” date (10 years from initial power
up) in permanent marker on the label prior to installing the unit. For combination smoke/CO models,
two labels have been provided that have important information on what to do in case of a CO alarm.
Place one label at eye level on a wall near the alarm after it is mounted, and one near a fresh air source
such as a door or window, where you plan to gather after the alarm indicates the presence of carbon
monoxide.
