• 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.
Conditions that can produce carbon monoxide
• 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 connection vibrating loose from clothes
dryers, furnaces, or water heaters.
• Obstructions in or unconventional vent pipe designs
which 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 garage, or near a home.
What CO alarms can and cannot do
CO alarms provide early warning of the presence of CO,
usually before a healthy adult would experience symptoms.
This early warning is possible, only if your CO alarm is located,
installed, and maintained as described in this manual.
Because carbon monoxide is a cumulative poison, long-term
exposures to low levels may cause symptoms, as well as
short-term exposures to high levels. This unit has a time-
weighted alarm, the higher the level of CO present, the sooner
the alarm will be triggered.
This CO alarm can only warn you of the presence of CO. It
does not prevent CO from occurring, nor can it solve an
existing CO problem. If your unit has alarmed and you’ve
provided ventilation by leaving your windows and doors open,
the CO buildup may have dissipated by the time help
responds. Although your problem may appear to be
temporarily solved, it is crucial that the source of the CO is
determined and that the appropriate repairs are made.
CO alarms have limitation. Like any other electronic device,
CO alarms are not fool-proof. CO alarms have a limited
operational life. You must test your CO alarm weekly, because
it could fail to operate at any time.
If your CO alarm fails to test properly, or if its self-diagnostic
test reveals a malfunction, immediately have the unit replaced.
This alarm will not monitor CO levels while in a trouble
condition.
The CO alarm can only sense CO that reaches the unit’s
sensor. It is possible that CO may be present in other areas
without reaching the alarm. The rate and ability with which CO
reaches the alarm may be affected by:
• Doors or other obstructions.
• Fresh air from a vent, an open window, or other source.
• CO being present on one level of the home and not
reaching a CO alarm installed on a different level. (For
example, CO in the basement may not reach an alarm on
the second level, near the bedrooms).
For these reasons, we recommend you provide complete
coverage by placing a CO alarm on every level of the home.
Important warning statements
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 CO 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.
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. It
is not suitable for installation in hazardous locations as defined
in the National Electric 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.
