WHAT YOU SHOULD KNOW ABOUT CO

Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is
a cumulative poison. Even low levels of CO have been shown to cause brain and other vital
organ damage in unborn infants with no effect on the mother.

The following symptoms are related to CARBON MONOXIDE 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, cardiorespiratory failure, death.
Many cases of reported CARBON MONOXIDE POISONING indicate that victims are aware

they are not well, but they become so disoriented that they are unable to save themselves
by either exiting the building or calling for assistance. Young children and household pets
may be the first affected.

Your CO alarm is designed to detect the toxic CO fumes that result from incomplete
combustion, such as those emitted from appliances, furnaces, fireplaces and auto exhaust.

A CO alarm is NOT A SUBSTITUTE for other combustible gas, fire or smoke alarms. This
carbon monoxide alarm is designed to detect carbon monoxide gas from ANY source of
combustion.

This alarm will only indicate the presence of carbon monoxide gas surrounding its sensor.
Carbon monoxide gas may be present in other areas.

This product is intended for use in ordinary indoor locations of family living units. It is not
designed to measure compliance with Occupational Safety and Health Administration
(OSHA) commercial or industrial standards. Individuals with medical problems may consider
using warning devices which provide audible and visual warnings for carbon monoxide
concentrations under 30 PPM.

WHAT YOU SHOULD DO IF THE ALARM SOUNDS

Never disconnect a CO alarm to silence an alarm. The alarm will automatically sense when
the level of CO in the air falls below the danger level. You should stay outside the residence
in fresh air until the alarm is silenced. When the alarm sounds, do not stand too close to the
alarm. The sound produced by the alarm is loud because it is designed to awaken a person
in an emergency. Prolonged exposure to the alarm at a close distance may be harmful to
your hearing.

Two self-adhesive labels have been provided with instructions indicating what to do if the
alarm sounds. Add the phone numbers of your emergency services provider and a qualified
technician to each label. Place one of the labels in a visible area next to the alarm and
place the other label near a source of fresh air which will be used as a gathering place if the
alarm sounds.

IMPORTANT CONSIDERATIONS

YOUR CARBON MONOXIDE ALARM HAS BEEN DESIGNED AND IS
WARRANTED TO OPERATE FOR FIVE YEARS.

NOTE: MANUFACTURER RECOMMENDS REPLACEMENT OF ALARM FIVE
YEARS AFTER DATE OF PURCHASE.

Activation of this device indicates the presence of carbon monoxide
(CO) which can kill you. If alarm sounds:

1. Operate test/reset button;

2. Call your emergency services, fire department or 911;

3. 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 reenter 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.

4. After following steps 1-3, if your alarm reactivates within a 24 hour period, repeat steps
1-3 and call a qualified appliance technician; to
investigate for sources of CO from fuel burning eq u ip m e nt and appliances and inspect
for proper operation of this equipment. If problems are identified during this inspection,
have the equipment serviced immediately. Note any combustion equipment not
inspected by the technician and consult the manufacturers' instructions or contact the
manufacturer(s) directly for more information about CO safety and this equipment.
Make sure that motor vehicles are not, and have not been, operating in an attached
garage or adjacent to the residence.

INSTALLING THE ALARM FOR RESIDENTIAL USE

LOCATION

One of the most important considerations in any CO alarm system is the location of the
alarms. Statistics of the National Fire Protection Association (NFPA) show that most of the
fatal CO occurrences happen at night while people are sleeping.

Early warning of CO is best achieved by the installation of CO alarms on all floors and
areas of the household including attached garages. Placement of a alarm in a garage may
cause an alarm due to CO from automotive exhaust.

RECOMMENDATIONS

– Put a CO alarm inside each bedroom where the occupant closes the door while sleeping.

Particulate smoke can be blocked by a closed door, but CO fumes are likely to get
through.

– A CO alarm should be installed in any family living unit containing a fuel-burning appliance

or fireplace or having an attached garage.

– A CO alarm should be centrally located outside of each separate sleeping area in the

immediate vicinity of the bedrooms. Where bedrooms are separated and audibility of the
alarm to occupants within the bedroom area could be seriously impaired, more than one
unit could be needed.

LOCATIONS TO AVOID

Nuisance alarms are caused by placing alarms where they will not operate properly.
To avoid nuisance alarms, do not place alarms:

– Within 1 foot (.3m) from fluorescent lights. Electronic noise may cause false alarms.
– Within 5 feet (1.5m) of any cooking appliance.
– Closer than 20 feet (6m) away from a furnace or other fuel burning heat source or

fuel burning appliances such as a water heater.

– Near an open window or door, because the fresh air entering the opening may

delay CO from reaching the alarm.

– In extremely humid areas. This alarm should be at least 10 feet (3m) from a bath or

shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room or other
source of high humidity.

– In very cold or very hot environments or in unheated buildings or outdoor rooms

where the temperature can go below or above the operating range of the alarm.
Temperature limits for proper operation are 40o to 100oF (4.4o to 37.8oC).

– In turbulent air, such as near ceiling fans, heat vents, air conditioners, fresh air

returns or open windows. Blowing air may prevent CO from reaching the sensors.

– Good ventilation is recommended when household cleaning supplies or similar

contaminants are used.

– Excessive spillage or reverse venting of fuel burning appliances caused by outdoor

ambient conditions, such as:
– Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent

pipes (cold/humid air with extended periods between cycles).
– Negative pressure differential resulting from the use of exhaust fans.
– Simultaneous operation of several fuel burning appliances competing for limited

internal air.
– Vent pipe connections vibrating loose from clothes dryers, furnaces, or water

heaters.
– Obstructions in or unconventional vent pipe designs which can amplify the above

situations.

– Extended operation of unvented fuel burning devices (range, oven, fireplace, etc.)
– Temperature inversions which can trap exhaust gasses near the ground.
– Car idling in an open or closed attached garage, or near a home.

What Levels of CO Cause an Alarm?

Underwriters Laboratories Inc. UL2034 defines three specific alarm points by which
all residential CO alarms must alarm. They are measured in parts per million (ppm) of
CO over time (in minutes).

UL2034 Required Alarm Points:

• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM BETWEEN 4 and 15
MINUTES.

• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM BETWEEN 10 and 50
MINUTES.

• If the alarm is exposed to 70 ppm of CO, IT MUST ALARM BETWEEN 60 and 240
MINUTES.
