PLUG THE ALARM INTO AN OUTLET
This CO Alarm should receive continuous electrical power. Do not plug
this Alarm into an outlet controlled by a dimmer or switch.
1. Plug the unit into a standard UNSWITCHED 120V AC outlet. The unit
should be located where it can wake you if it alarms at night.
2. Make sure the POWER/ALARM light shines continuously when you plug it
in. The horn may “chirp” during power up, or when power is restored after
an outage.
3. Test by pressing the Test/Silence/Scroll button firmly until the unit sounds:
4 beeps, pause, 4 beeps. During testing, the POWER/ALARM light will
flash and “888” will appear briefly on the Display. This is normal.
PREPARE YOUR ALARM LABELS
Find the pair of self-adhesive labels included with this CO Alarm.
• On each label write in the phone number of your emergency responder
(like 911) and a qualified appliance technician.
• Place one label near the CO Alarm, and the other label in the “fresh air”
location you plan to go if the alarm sounds.
NOTE: A qualified appliance technician is defined as “a person, firm, corpora-
tion, or company that either in person or through a representative, is engaged
in and responsible for the installation, testing, servicing, or replacement of
heating, ventilation, air conditioning (HVAC) equipment, combustion appli-
ances and equipment, and/or gas fireplaces or other decorative combustion
equipment.”
HOW TO INSTALL YOUR CO ALARM
IMPORTANT! Read all instructions before using this product.
Quick reference:
• Plug the Alarm into a standard
120V unswitched outlet.
• Test the CO Alarm.
USING THE SILENCE FEATURE
The Silence Feature is intended to temporarily silence your CO Alarm’s horn
while you correct the problem—it will not correct a CO problem. While the
alarm is silenced, it will continue to monitor the air for CO.
To Activate the Silence Feature:
Press and hold the Test/Silence/Scroll button until the horn is silent.
Once you activate the Silence Feature: the Silence cycle will last
approximately 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.
The Silence Feature is for your convenience only and will not correct a
CO problem. Always check your home for a potential problem after any
alarm. Failure to do so can result in injury or death.
NEVER disconnect your CO Alarm to silence the horn. Use the Silence
Feature. Unplugging the CO Alarm removes your protection!
IF YOUR CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence of carbon monoxide
(CO) which can kill you. When your CO Alarm sounds, you must not
ignore it!
IF THE ALARM SIGNAL SOUNDS:
1. Operate the Test/Silence button.
2. Call your emergency services, fire department or 911. Write down the
number of your local emergency service here:
__________________________________________________________________
3. Immediately move to fresh air—outdoors or by an open door or window.
Do a head count to check that all persons are accounted for. Do not re-
enter the premises, or move away from the open door or window until the
emergency services responder has arrived, the premises have been aired
out, and your CO Alarm remains in its normal condition.
4. After following steps 1-3, if your CO Alarm reactivates within a 24-hour
period, repeat steps 1-3 and call a qualified appliance technician to inves-
tigate 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 manufacturers 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. Write down the number of a qualified
appliance technician here:

Alarms have various limitations. See "General Limitations of CO Alarms"
for details.
“ALARM-MOVE TO FRESH AIR”
If you hear the alarm horn and the red light is
flashing, move everyone to a source of fresh air.
DO NOT unplug the CO Alarm!
TESTING AND MAINTENANCE
WEEKLY TESTING
Test the Carbon Monoxide Alarm once a week.
Press 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.
• The Test/Silence/Scroll button is the only proper way to test the CO
Alarm. 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.”
• Vacuum 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. Test the Alarm again after vacuuming.
DO 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
permanent damage.
Household cleaners, aerosol chemicals and other contaminants can affect the
sensor. When using any of these materials near the CO Alarm, make sure the
room is well ventilated.
If 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
and all traces of fumes clear, plug the unit back in and retest it.
WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not
burn completely, or are exposed to heat (usually fire). Electrical appliances
typically do not produce CO.
These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,
kerosene, and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, are improperly ventilated, or malfunction, CO levels can rise quickly.
CO 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.
