transient CO Problems: "transient" or on-again-off-again CO problems can
)e caused by outdoor conditionsand other special circumstances.
The following conditions can result in transient CO situations:
1.
Excessive
spillage
or
reverse
venting
of
fuel
appliances
causedby
outdoor
conditions
such
as:
•
Wind
direction
and/or
velocity,
including
high,
gusty
winds.
Heavy
airin
theventpipes
(cold/humid
air
with
extended
periods
between
cycles).
•
Negative
pressure
differential
resulting
from
the useof
exhaust
fans.
•
Several
appliances
running
at the sametime
competing
for
limited
fresh
air.
• Ventpipe connections
vibrating
loose fromclothes dryers,furnaces, or
water
heaters.
• Obstructions in or unconventional vent pipe designs which can amplify
the
above
situations.
2.
Extended
operation
of
unvented
fuel
burning
devices
(range,
oven,
fireplace).
3.
Temperature
inversions,
which
cantrap
exhaust
closetothe
ground.
4. Car
idling
inan openor closedattachedgarage,or neara home.
These conditions are dangerous because they can trap exhaust in your
home. Since
these
conditions can
come
and go, they are also hard to
recreate during a CO investigation.

WHAT

Jnderwriters Laboratories Inc. Standard UL2034requires residential CO

ThisCO
Alarm

extremely
high
ina short
period
of

orifCO
levels
reach
a
certain
minimum
overa
long
period
of
time.
TheCO
Alarm
generally
soundsan
alarm
before the onset of symptoms inaverage, healthyadults.
Why
isthis
important?
Because
you
need
tobe
warned
ofa
potential
CO
problem
while
you
can
still
react
in
time.
In
many
reported
casesof
CO
exposure,
victims
may
be
aware
that
they
arenot
feeling
well,
but
become
disorientedand can no longerreact
well
enoughto exitthe
building
or get
help.
Also,
young
children
andpets
may
bethe
first
affected.
The
average
healthy
adult
might
not
feel
any
symptoms
when
the
CO
Alarm
sounds.
However,
people
with
cardiac
or
respiratory
problems,
infants,
unborn
babies,
pregnant
mothers,
or
elderly
people
canbe
more
quickly
and
severely
affected
by
CO.
If
you
experience
even
mild
symptoms
of
CO
poisoning,
consult
your
doctor
immediately!

However,
IftheCO

COAlarmsarenot a substitute fora smoke

Although

This
CO

senses COthat maybe escaping unnoticed
from
malfunctioning
furnaces,

Early
warning
of

requires
the
installation
of
smoke

COAlarmsarenot a substituteforWeinsurance.
Though
theseCO

in
any
way
that
they
will
protect

Homeowners
and

must
still Insure their lives.
COAlarmshave a
limited
life.
Although
the CO
Alarm
and
all
ofitsparts
havepassed
many
stringent
tests andare
designed
to beas
reliable
as
possible,
any
of
these
parts
could
fail
at
any
time.
Therefore,
you
must
test
your COAlarmweekly.
COAlarmsarenot
foolproof.
Like
all
other
electronic
devices,
CO
Alarms
have
limitations.
They
can
only
detectCOthat reachestheirsensors.
They
may
not
give
early
warning
to
rising
CO
levels
ifthe
CO
is
coming
from
a
remotepartofthe
home,
away
from
the CO
Alarm.
This CO Alarm is
intended
for residential
use.
It is
not
intended
for
use in industrialapplications where Occupational Safety and Health
Administration
(OSHA)
requirements for carbon monoxide detectors
must
be
met.
COalarmsmay notwaken all
individuals.
If
children
orothersdo not
readily
waken to the sound of the CO alarm,or ifthere are infantsor
family
members
with
mobility
limitations,
make
surethat
someone
is
assigned

them
in
the
event
of
an
emergency.
QO

contains
a
sealed,
non-replaceable battery.
CO Alarms for Solar or Wind Energy
users
and battery
backup
power
systems:
AC
powered
CO
Alarms
should
only
be
operated
with
trueor pure
sinewave
inverters.
Operating
this
Alarm
with
most
battery-powered
UPS
(uninterruptible

products
orsquare
wave
or
"quasi

inverters will damage the Alarm. Ifyouare not sure about your
inverter
or
UPS
type,please
consult
with
the
manufacturer
to
verify.
This CO Alarmwillnot
sense
carbon monoxide that does not reach the
sensor. This CO
Alarm
will
onlysense CO at the sensor. CO maybe present
inother areas. Doorsor otherobstructions mayaffectthe rate at whichCO
reaches the CO
Alarm.
Forthis reason, ifbedroomdoors are
usually
closed
at
night,
we
recommend
you
install
a
CO
Alarm
in
each
bedroom
and
in
the
hallway between them.
COAlarmsmaynot sense COon anotherlevelof the home.For
example,
a CO
