SYMPTOMS OF CO POISONING
These symptoms are related to CO POISONING and should be discussed
with ALL household members.
Mild Exposure:
Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).
Medium Exposure:
Throbbing headache, drowsiness, confusion, fast heart rate.
Extreme Exposure:
Convulsions, unconsciousness, heart and lung failure. Exposure to carbon
monoxide can cause brain damage, death.
This CO Alarm measures exposure to CO over time. It alarms if CO levels
are extremely high in a short period of time, or if CO levels reach a certain
minimum over a long period of time. The CO Alarm generally sounds an alarm
before the onset of symptoms in average, healthy adults. Why is this important?
Because you need to be warned of a potential CO problem while you can still
r
eact in time. In many reported cases of CO exposure, victims may be awar
e
that they are not feeling well, but become disoriented and can no longer react
well enough to exit the building or get help. Also, young children and pets may
be the 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 can
be more quickly and severely affected by CO. If you experience even mild
symptoms of CO poisoning, consult your doctor immediately!
U
SING THE SILENCE FEATURES
T
he Silence Feature is intended to temporarily silence your CO Alarm’s horn
w
hile you correct the problem—it will not correct a CO problem. While the
a
larm is silenced, it will continue to monitor the air for CO.
To Activate the Silence Feature: press and hold the Test/Silence/Scroll
b
utton until the horn is silent.
O
nce you activate the Silence Feature:
t
he Silence cycle will last
a
pproximately 4 minutes.
•
If CO levels drop below alarm levels after 4 minutes, the unit will return to
normal operation and remain silent.
• If CO levels do not drop below alarm levels, the unit will alarm again.
T
he Silence Feature is for your convenience only and will not correct a
CO problem. Always check your home for a potential problem after any
a
larm. Failure to do so can result in injury or death.
NEVER disconnect your CO Alarm to silence the horn. Use the Silence
F
eature. Unplugging the CO Alarm and removing the batteries removes
y
our protection!
SILENCING THE LOW BATTERY WARNING
T
his silence feature can temporarily quiet the low battery warning “chirp” for
up to 8 hours without having to remove the battery. You can silence the low
b
attery warning “chirp” by pressing the Test/Silence button on the alarm cover.
O
nce the low battery warning “chirp” silence feature is activated, the unit
c
ontinues to flash the red light once a minute for 8 hours; the word “bat”
will flash on and off on the display. After 8 hours, the low battery “chirp”
w
ill resume.
R
eplace the battery as soon as possible, this unit will not
o
perate without battery power!
T
o deactivate this feature:
P
ress the Test/Silence button again. The unit will
go into Test Mode and the low battery warning will resume (LED flashes and
u
nit sounds “chirp” once a minute.)
If you cannot silence the low battery
warning, re
place your battery
immediately.
TESTING AND MAINTENANCE
WEEKLY TESTING
You can test this CO Alarm by pressing the Test/Silence/Scroll button on the
Alarm cover until alarm sounds.
During testing, you will hear a loud alarm sequence – 4 beeps, pause, 4 beeps,
pause.
• If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposure at close range may be harmful to your hearing. When
testing, step away when horn starts sounding.
• NEVER use vehicle exhaust! Exhaust may cause permanent damage
and voids your warranty.
REGULAR MAINTENANCE
To keep the CO Alarm working properly:
• Test it every week as described in “Weekly Testing.”
•
V
acuum the CO Alarm cover at least once a month, using the soft brush
attachment. Never use water, cleaners, or solvents, since they may dam-
age the unit. T
est the Alarm again after vacuuming.
• Replace the battery immediately when you see/hear the
“Low Battery W
arning”.
The Low (or Missing) Battery Warning:
The hor
n will “chirp” once a minute and the wor
d

R
EPLACING THE BATTERY
C
hoosing a Replacement Battery:
T
his unit requires one standard 9V alkaline battery. The following alkaline
b
atteries are acceptable as replacements: Duracell #MN1604 or MX1604;
Eveready “Energizer” 522. You can also use an Ultralife 9 volt lithium battery
#
U9VL for longer service life between battery changes. These replacement
b
atteries are commonly available at local retail stores.
Use only the alkaline or lithium replacement batteries listed. The unit may not
o
perate properly with other batteries. Never use rechargeable batteries since
t
hey may not provide a constant charge.
D
O NOT spray cleaning chemicals or insect sprays directly on or near
the CO Alarm. DO NOT paint over the CO Alarm. Doing so may cause
p
ermanent damage.
H
ousehold cleaners, aerosol chemicals and other contaminants can affect
the sensor. When using any of these materials near the CO Alarm, make sure
t
he room is well ventilated.
I
f your home is being fumigated, unplug the unit temporarily and put it where
it will not be exposed to chemicals or fumes. When fumigation is complete
a
nd all traces of fumes clear, plug the unit back in and retest it.
WHAT YOU NEED TO KNOW ABOUT CO
WHA
T IS CO?
CO is an invisible, odorless, tasteless gas pr
oduced when fossil fuels do not
burn completely, or are exposed to heat (usually fire). Electrical appliances
t
ypically do not produce CO.
These fuels include: Wo
od, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
t
ained, are improperly ventilated, or malfunction, CO levels can rise quickly.
C
O is a real danger now that homes are more energy efficient. “Air-tight”
homes with added insulation, sealed windows, and other weatherproofing
can “trap” CO inside.
