TESTING AND MAINTENANCE
WEEKLY TESTING
Press the Test/Silence button on the Alarm cover until alarm sounds. During testing, you will hear a loud alarm sequence – 4 beeps, pause, 4 beeps, pause.
The alarm sequence should last
•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.”
•Vacuum the CO Alarm cover at least once a month, using the soft brush attachment. Never use water, cleaners, or solvents, since they may damage the unit. Test the Alarm again after vacuuming.
•Replace the battery immediately when you hear the “Low Battery Warning”.
The Low (or Missing) Battery Warning: The horn will “chirp” once a minute.
REPLACING THE BATTERY
Choosing a Replacement Battery:
This CO Alarm requires two standard AA batteries. The following batter- ies are acceptable as replacements: Energizer E91. These replacement batteries are commonly available at local retail stores.
Use only the alkaline or lithium replacement batteries listed. The unit may not operate properly with other batteries. Never use rechargeable batteries since they may not provide a constant charge.
To Replace The Batteries:
1.Open the battery compartment.
2.Use the thumb guide to remove the old batteries.
3.Insert the new batteries, making sure they snap completely into the battery compartment and cannot be shaken loose.
4.Close the battery compartment, then test the battery
5.Plug the CO Alarm back into the outlet.
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 appli- ances 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 maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real danger now that homes are more energy efficient.
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
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.
Some individuals are more sensitive to CO than others, including people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can be more quickly and severely affected by CO. Members of sensitive populations should consult their doctors for advice on taking additional precautions.
FINDING THE SOURCE OF CO AFTER AN ALARM
Carbon monoxide is an odorless, invisible gas, which often makes it difficult to locate the source of CO after an alarm. These are a few of the factors that can make it difficult to locate sources of CO:
•House well ventilated before the investigator arrives.
•Problem caused by “backdrafting.”
•Transient CO problem caused by special circumstances.
Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO. BRK Brands, Inc. shall not be obli- gated to pay for any carbon monoxide investigation or service call.
HOW CAN I PROTECT MY FAMILY?
A CO Alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before carbon monoxide levels become threatening for average, healthy adults.
A CO Alarm is not a substitute for proper maintenance of home appliances.
To help prevent CO problems and reduce the risk of CO poisoning:
•Clean chimneys and flues yearly. Keep them free of debris, leaves, and nests for proper air flow. Also, have a professional check for rust and corrosion, cracks, or separations. These conditions can prevent proper air movement and cause backdrafting. Never “cap” or cover a chimney in any way that would block air flow.
•Test and maintain all
•Make regular visual inspections of all
A yellow flame means fuel is not being burned completely and CO may be present. Keep the blower door on the furnace closed. Use vents or fans when they are available on all
•Check for exhaust backflow from CO sources. Check the draft hood on an operating furnace for a backdraft. Look for cracks on furnace heat exchangers.
•Check the house or garage on the other side of shared wall.
•Keep windows and doors open slightly. If you suspect that CO is escaping into your home, open a window or a door. Opening windows and doors can significantly decrease CO levels.
In addition, familiarize yourself with all enclosed materials. Read this manual in its entirety, and make sure you understand what to do if your CO Alarm sounds.
