Information about carbon monoxide
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 manual and discuss your
CO Alarm emergency procedure with all 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 either by 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.
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 attached 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 however, 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.
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.
CO Alarms should not be used to detect the presence of
natural gas (methane), propane, butane, or other
combustible fuels.
Instruct children never to touch or otherwise interfere
with the alarm. Warn children of the dangers of CO
poisoning.
