• This CO alarm can quickly alert you to the
presence of CO levels equal to or greater
than 70 ppm.
• This alarm cannot prevent toxic CO
emissions. (Regular maintenance of
combustion appliances and their vent
systems is advised.)
• This alarm cannot protect you from hazards
such as gas leaks or explosions. The
ultimate protection against toxic CO gas is
your responsibility.
• This alarm is designed to detect carbon
monoxide entering its sensing chamber. It
does not sense combustible gas such as
natural gas, propane or butane, heat,
smoke, or flames.
To protect yourself and your family from toxic
CO poisoning, create an effective, compre-
hensive safety program:
1. Install CO detectors correctly, using the
instructions in this Owner’s Guide
2. Replace batteries every year (or sooner if
intermittent chirp sound is heard, indicat-
ing a low battery condition).
3. Develop a family escape plan and prac-
tice it with your entire family, especially
small children.
a. Draw a floor plan of your home and
find two ways to exit each room; and
an additional way to exit a bedroom
without opening the door.
b. Teach your children what the CO
alarm signal means and how to exit
your home by themselves, if neces-
sary.
