IMPORTANT INFORMATION ABOUT CARBON MONOXIDE ALARM
1. WHAT IS CARBON MONOXIDE?
Carbon monoxide is a colorless, odorless and tasteless poison gas that can be fatal when inhaled. CO blinds to the hemoglobin
in the blood and inhibits its capacity to carry oxygen. CO kills hundreds of people each year and injures many more because it
is difficult to be detected with the human senses. In high concentrations, CO can kill in minutes.
2. SOURCES OF CARBON MONOXIDE
Inside your home, appliances used for heating and cooking are the most likely sources of CO. Vehicles running in attached
garages can also produce dangerous levels of CO. CO can be produced when burning any fossil fuel, such as gasoline, propane,
natural gas, oil and wood. It can be produced by any fuel-burning appliance that is malfunctioning, improperly installed, or
not ventilated correctly, such as:
z Automobiles, furnaces, gas ranges/stoves, gas clothes dryers, water heaters, portable fuel burning space heaters and
generators, fireplaces, wood-burning stoves and certain swimming pool heaters.
z Blocked chimneys or flues, back drafts and changes in air pressure, corroded or disconnected vent pipes, loose or cracked
furnace exchangers.
z Vehicles and other combustion engines running in an open or closed garage, attached or near a home.
z Burning charcoal or fuel in grills and hibachis in an enclosed area.
3. CONDITIONS THAT CAN RESULT IN TRANSIENT CO SITUATION IN THE HOME:
The following conditions can result in transient CO situations:
z 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).
z Negative pressure resulting from the use of exhaust fans.
z Simultaneous operation of several fuel-burning appliances competing for limited internal air.
z Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters.
z Obstructions in, or unconventional, vent pipe designs which can amplify the above situations.
z Extended operation of unvented fuel-burning devices (range, oven, fireplace, etc.).
z Temperature inversions which can trap exhaust gases near the ground.
z Vehicle idling in an open or closed garage, or near a home.
To be safe, know the possible sources of CO in your home. Keep fuel-burning appliances and their chimneys and vents in good
working condition. Learn the early symptoms of exposure, and if you suspect CO poisoning, move outside to fresh air and get
emergency help. Your first line of defense is an annual inspection and regular maintenance of your appliances. Contact a
licensed contractor or call your local utility company for assistance.
4. SYMPTOMS OF CO POISONING
35 ppm
The maximum allowable concentration for continuous exposure for healthy adults in any 8 hour period
200 ppm
Slight headaches, fatigue, dizziness, nausea after 2-3 hours
400 ppm Frontal headaches within 1-2 hours, life threatening after 3 hours
800 ppm Dizziness, nausea and convulsions within 45 minutes. Unconsciousness within 2 hours and death within 3 hours
1600 ppm Headache, dizziness and nausea within 20 minutes. Death within 1 hour.
6400 ppm Headache dizziness and nausea within 1-2 minutes
The following symptoms related to CO POISONNING and are to 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.
Many cases of reported CARBON MONOXIDE POISONING indicate that while victims are aware they are not well. They
become so disoriented they are unable to save themselves by either the building or calling for assistance. Yong children and
household pets are typically the first affected.
5. IMPORTANT SAFEGUARDS
Installation of your CO alarm is only one step in your safety plan. Educate yourself and family to the sources and
symptoms of CO poisoning and how to use your carbon monoxide alarm:
z Test your CO alarm weekly
z Replace the battery immediately once depleted
z Buy appliances accepted by a recognized testing laboratory
z Install the appliances properly, following the manufacturer’s instructions
z Have installations done by professionals
z Have your appliances checked regularly by a qualified serviceman
z Clean chimneys and flues yearly
z Make regular visual inspections of all-fuel-burning appliances
z Check appliances for excessive rust and scaling
z Do not barbecue indoors, or in attached garage
z Open windows when a fireplace or wood burning stove is use
z Be aware of CO poisoning symptoms
DO NOT:
z Burn charcoal inside your home, RV, camper, tent or cabin
z Install, convert or service fuel burning appliances without proper knowledge, skill and expertise
z Use a gas range, oven or clothes dryer for heating
z Operate unvented gas burning appliances using kerosene or natural gas in closed room
z Operate gasoline powered engines indoors or in confined areas
z Ignore a safety device when it shuts an appliance
z Ignore any warning from your CO alarm

WARNING: This product may not alarm at low carbon monoxide levels. Individuals with medical problems may
consider using warning devices which provide audible concentrations under 30 ppm.
Hush Feature
WARNING:
• The Hush 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 remove the battery from your CO Alarm to silence the horn. Use the silence feature. Removing the battery removes
your protection! See “If Your CO Alarm Sounds” for details on responding to an alarm.
The Hush Feature is intended to temporarily silence your CO Alarm’s alarm 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 .When CO reaches alarm levels the
alarm will sound— repeating horn pattern: 4 beeps, a pause, 4 beeps, etc. Press and hold the Test/Silence button until the horn is
silent. The initial Silence cycle will last approximately 4 minutes.
NOTE: After initial 4-minute Silence cycle, the CO Alarm re-evaluates present CO levels and responds accordingly. If CO
levels remain potentially dangerous or start rising higher the alarm will start sounding again.
While the detector is silenced:
If the CO Alarm...
This means...
Is silent for only 4 minutes, then starts sounding
loudly—4 beeps, pause, 4 beeps, pause
CO levels are still potentially dangerous.
If the CO Alarm...
This means...
Remains silent after you pressed the Test/Hush
button
CO levels are dropping.
Low Battery Signal
The horn “chirps” once every minute. This warning should last for up to 30 days, but you should replace the battery as soon as
possible.
NOTE: With normal use the battery will last for 1 year minimum. However, battery life will be reduced if either a fault occurs
with the battery or the alarm remains in alarm for long periods of time.
Unit Malfunction
Your CO alarm performs an internal self-diagnosis to make sure that it is functioning properly. If the unit has
detected an error, there is a failure warning. The horn sounds 3 short “chirps” every minute. Push and hold
Test/Hush button, Red LED is on. Release Test/Hush button, Red LED is off. In case of the above failure
warning happened, the CO alarm should be replaced to a new one.
End of Life warning
The horn sounds 2 short “chirps” following with 1 long “chirp”every minute. In case of the above warning
happened, the CO alarm is end of life, and the CO alarm should be replaced to a new one.
If your CO alarm sounder is beeping, and you are not sure if it is a CO alarm or malfunction alert, reset the alarm, open
windows for ventilation, turn off fuel-burning appliance (like kerosene or oil heaters, furnaces, wood-burning stoves, water
heaters, or other fossil-fuel burning appliances)
Never ignore a CO unit’s alarm. A true alarm is an indication of potentially dangerous levels of carbon monoxide. CO alarms
are designed to alert you to the presence of carbon monoxide before an emergency, before most people would experience
symptoms of carbon monoxide poisoning, giving you time to resolve the problem calmly.
TESTING THE CO ALARM
• Test the CO Alarm once a week. If the CO Alarm ever fails to test
correctly, have it replaced immediately! If the CO Alarm is not working
properly, it cannot alert you to a problem.
• 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.
Push and hold the Test/Hush button on the cover until the LED flashes. The alarm horn will sound 4 beeps, a pause, then 4
beeps. The ALARM (RED) light will flash.
The alarm sequence should last 5-6 seconds. If it does not alarm, make sure fresh batteries are correctly installed, and test it
again. If the unit still does not alarm, replace it immediately.
Testing with Carbon Monoxide
The unit checks for CO every 4 seconds and as soon as it detects CO it flashes the red light (as per Table A) to
confirm that is detecting CO gas.
The unit can be tested with CO by using one of the kits that comes with CO either in a glass phial or aerosol can.
Follow the instructions on the kit. When it senses the CO,it will have a Pre-Alarming status, please refer to

Golden Power G6F22; Golden Power GL6F22A.
CO ALARM REPLACEMENT:
CO Alarms don’t last enduringly. CO Alarms are sophisticated electronic devices with many parts. Although the alarm and its
component parts have undergone stringent tests, and are designed to be very reliable, it is possible that parts can fail. Therefore,
you should test your CO Alarm weekly. The CO Alarm must be replaced in 3 years or by the recommended replacement date on
the label of unit on back side.
CLEAN THE CO ALARM
Clean the CO alarm at least once a month to remove dust, dirt, or debris. Using the soft brush or wand
attachment to a vacuum cleaner, vacuum all sides and cover of CO alarm. Be sure all the vents are free of debris.
If necessary, use a damp cloth to clean CO alarm cover.
IMPORTANT: Do not attempt to remove the cover to clean inside the CO alarm. This will void your warranty.
NOTE:
z Never use detergents or solvents to clean the alarm. Chemicals can permanently damage or temporarily contaminate the
sensor.
z Avoid spraying air fresheners, hair spray, paint or other aerosols near the alarm.
z Do not paint the alarm. Paint will seal the vents and interfere with proper sensor operation.
Move the CO Alarm to a remote location, to prevent possible damage to or contamination of the sensor if you will be staining
or stripping wood floors or furniture, painting, wall-papering, or using aerosols or adhesives.
WARNING: Reinstall the CO Alarm as soon as possible to assure continuous protection.
The following is a list of substances that at high levels can damage the sensor or cause temporary false alarm that is not a
carbon monoxide alarm.
Ethylene, ethanol, alcohol, iso-propanol, benzene, toluene, ethyl acetate, hydrogen, hydrogen sulfide and sulfur dioxide.
Also most aerosol sprays, alcohol based products; paint, thinner, solvent, adhesive, hair spray, after shave, perfume, auto
exhaust (cold start) and some cleaning agents.
WHAT TO DO IF THE ALARM SOUNDS
WARNING
Actuation of your CO alarm indicates the presence of carbon monoxide (CO), which can kill you. If alarm sounds:
1. Operate reset button
2. Call your emergency services
3. Immediately move to fresh air-outdoors or by an open door/window. Make sure that all persons are alerted. Do not
re-enter the premises nor move away from the open door/window until emergency services responders have arrived,
the premises have been aired out, and your alarm remains in its normal condition.
4. After following steps 1-3, if your alarm reactivates within a 24 hour period, repeat steps 1-3, and call a qualified
appliance technician to investigate 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 manufacturer’s instructions, or contact
the manufacturers directly for more information about CO safety and the equipment. Make sure that motor vehicles are
not, or have not been, operating in a garage attached or adjacent to the residence. Never restart the source of a CO
problem until it has been corrected.
WARNING: Never ignore the sound of the alarm! If the alarm is sounding, pressing the test/reset button will
terminate the alarm. If the CO condition that caused the alert in the first place continues, the alarm will reactivate. If the
unit alarms again within six minutes, it is sensing high levels of CO which can quickly become a dangerous situation.
