CARBON MONOXIDE ALARM

OWNER'S MANUAL

PLEASE READ AND SAVE!

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:

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.

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

WARNING: 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.

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 reset/silence 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 equipment 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.

MOUNTING LOCATION

This CO alarm can be mounted on the wall or ceiling.
WALL LOCATION: Locate the top of the alarm not more than 6 feet from the floor.
CEILING LOCATION: Alarm should be mounted as close as possible to the center of a hallway or

room. If this is not possible, the edge of the alarm should be at least 4 inches from any wall.

FIGURE 3

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 5 feet (1.5m) of any cooking appliance.
 Near an open window or door, because the fresh air entering the opening may delay CO from

reaching the alarm.

 In damp or very humid areas or next to bathrooms with showers. Install alarms at least 10 feet (3m)

away from bathrooms.

 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 -100oF (4.4o -38oC).

 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.
