IMPORTANT: Seven (7) years after the initial power up, this alarm
will “beep” two times every 30 seconds to indicate that it is time
to replace the alarm. Replace the alarm immediately! It will not
detect CO in this condition.
To help identify the date to replace the alarm, a label has been affixed to
the side of the alarm. Write the “replace by” date (seven years from
power up) in a permanent marker on this label.
