Carbon Monoxide Alarm Procedure
If alarm sounds 4 quick beeps, 5 seconds off:
1) Immediately move to fresh air - outdoors or by an open door/
window. Do a head count to check that all persons are
accounted for. Do not re-enter the premises nor move away
from the open door/window until the emergency services
responders have arrived, the premises have been aired out, and
your alarm remains in its normal condition.
2) Call your emergency services (Fire Department or 911);
Never restart the source of a CO problem until it has been
corrected. Never ignore the sound of the alarm!
If the alarm is sounding, pressing the test/reset button will
terminate the alarm. If the CO condition that caused the alert
in the first place continues, the alarm will reactivate. If the
unit alarms again within six minutes, it is sensing high levels
of CO which can quickly become a dangerous situation.
WARNING:
Activation of the CO
Alarm indicates the presence of Carbon
Monoxide (CO) which can kill you.

What to do When the Alarm Sounds!

Welcome
Note: Many times throughout this User Guide, we will refer to
Carbon Monoxide as “CO”.
This Kidde carbon monoxide (CO) alarm is an important part of your
family’s home safety plan. This alarm has been designed and tested to
detect CO buildup in a residential environment. Your alarm is for use
specifically in the home, but not for use in a boat or recreational vehicle.
As an owner of a CO alarm, there are some basic facts you should know
about for your protection.
Many people think that CO alarms operate like smoke alarms. Like
smoke alarms, CO alarms monitor the air in your home and sound a
loud alarm to warn you of trouble. The way you respond to a CO alarm
is quite different than a smoke alarm. That’s because a house fire and a
CO problem are two distinctly different situations. If your smoke alarm
were to alarm, you would quickly be able to judge the level of danger
you were in with your senses. You can see and smell the smoke, feel the
heat, see, and possibly hear the fire burning. You can also readily see if
your smoke alarm is alarming in a non-emergency situation. Because your
sense of sight, smell, hearing and touch give you information, you can
almost instantly judge what action to take if you hear your smoke alarm.
CO is an invisible, odorless, tasteless and non-irritating gas – completely
undetectable to your senses. That’s why it is important to your safety
that you have a CO alarm.
Important Warning Statements
IMPORTANT: This carbon monoxide alarm is designed to detect
carbon monoxide from ANY source of combustion. It is NOT
designed to detect smoke, fire, or any other gas.
WARNING: Carbon monoxide alarms are not smoke alarms.
This carbon monoxide alarm is not a substitute for installing and
maintaining an appropriate number of smoke alarms in your
home.
This carbon monoxide alarm will not sense smoke, fire, or any
poisonous gas other than carbon monoxide even though carbon
monoxide can be generated by fire. For this reason you must
install smoke alarms to provide early warning of fire and to
protect you and your family from fire and its related hazards.
CAUTION: This alarm will only indicate the presence of carbon
monoxide at the sensor. Carbon monoxide may be present in
other areas.

Important Warning Statements
WARNING: This product is intended for use in ordinary indoor
locations of family living units, not for use in boats or
recreational vehicles. It is not designed to measure compliance
with commercial or industrial standards. It is not suitable for
installation in hazardous locations as defined in your local
building code.
The installation of this device should not be used as a substitute
for proper installation, use and maintenance of fuel burning
appliances, including appropriate ventilation and exhaust
systems. It does not prevent CO from occurring, nor can it solve
an existing CO problem.
WARNING: This device is designed to protect individuals from
acute effects of carbon monoxide exposure. It may not fully
safeguard individuals with specific medical conditions. If in doubt,
consult a medical practitioner.
Individuals with medical problems may consider using warning
devices which provide audible and visual signals for carbon
monoxide concentrations under 30 PPM.
This carbon monoxide alarm requires a continuous supply of
electrical power – it will not work without power. Models
without battery backup will not operate during power failure.
This alarm has not been investigated for carbon monoxide
detection below 70 PPM.

1. Information About Carbon Monoxide
General Carbon Monoxide Information
Carbon monoxide is a colorless, odorless and tasteless poison gas that
can be fatal when inhaled. CO inhibits the blood’s capacity to carry
oxygen.
Periodically review this alarm user guide and discuss your CO alarm
emergency procedure with all the members of your family. Never ignore
a CO alarm. A true alarm is an indication of potentially dangerous levels
of CO. CO alarms are designed to alert you to the presence of CO
before an emergency – before most people would experience symptoms
of CO poisoning, giving you time to resolve the problem calmly.
Determine if anyone in the household is experiencing symptoms of CO
poisoning. Many cases of reported CO poisoning indicate that while
victims are aware they are not well, they become so disoriented they
are unable to save themselves by either exiting the building or calling
for assistance. Also, young children and household pets may be the first
affected. You should take extra precautions to protect high-risk persons
from CO exposure because they may experience ill effects from CO at
levels that would not ordinarily affect a healthy adult.
Symptoms of CO Poisoning
The following common symptoms are related to CO poisoning and
should be discussed with ALL members of the household.
Mild Exposure:
Slight headache, nausea, vomiting, fatigue (often described as “flu-like”
symptoms).
Medium Exposure:
Severe throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure:
Unconsciousness, convulsions, cardio-respiratory failure, death.
If you experience even mild symptoms of CO poisoning, consult your
doctor immediately!
