WHAT YOU SHOULD KNOW ABOUT CO Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is a cumulative poison. Even low levels of CO have been shown to cause brain and other vital organ damage in unborn infants with no effect on the mother. The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed with ALL members of the household: MILD EXPOSURE Slight headache, nausea, vomiting, fatigue (often described as "flu-like" symptoms).
PAGE 3
INSTALLATION RECOMMENDATIONS Natural gas (methane) is typically supplied through a main utility line connected to your home. Early warning is best achieved by the installation of alarms on all floors and areas of the household. WHERE THIS ALARM SHOULD BE INSTALLED • Install an alarm inside each bedroom where the occupant closes the door while sleeping. • An alarm should be installed in any family living unit containing a fuel-burning appliance or fireplace or having an attached garage.
PAGE 4
RECOMMENDED PLACEMENT: NOTE: For any location, make sure no door or other obstruction could prevent the carbon monoxide or gas from reaching the alarm. WHERE THIS ALARM SHOULD NOT BE INSTALLED To avoid causing damage to the unit, to provide optimum protection, and to prevent unnecessary alarms. Do NOT locate this alarm: • In garages, kitchens, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas.
PAGE 5
• Good ventilation is recommended when household cleaning supplies or similar contaminants are used. • 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).  Negative pressure differential resulting from the use of exhaust fans.

IMPORTANT! The battery backup is designed to provide short-term emergency power to the CO and Gas Alarm. Actual backup time depends on the strength (freshness) of the battery. The battery backup will not work unless a good battery is properly installed. When the alarm utilizes battery backup power, the natural gas sensor will operate the alarm and will sample less frequently to extend battery life.
PAGE 7
IF THE CO ALARM SOUNDS: 1. Operate TEST/CO 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/window. Do a head count to check that all persons are accounted for.
PAGE 8
WEEKLY TESTING • NEVER use an open flame of any kind to test this unit. You might accidentally damage or set fire to the alarm or to your home. The built-in test switch accurately tests the unit's operation as required by ANSI/UL2034 Standard for Safety. NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty. • DO NOT stand close to the alarm when the horn is sounding. Exposure at close range may be harmful to your hearing.
PAGE 9
Use only the batteries specified. Use of different batteries may have a detrimental effect on the CO/Gas alarm. The constant exposures to high or low temperatures or high humidity may reduce battery life. IMPORTANT! The battery backup is designed to provide short-term emergency power to the alarm. Actual backup time depends on the strength (freshness) of the battery. The battery backup will not work unless a good battery is properly installed. NOTE: WEEKLY TESTING IS RECOMMENDED.

HOW CAN I PROTECT MY FAMILY FROM CO POISONING? This alarm is an excellent means of protection. It monitors the air and sounds a loud alarm before carbon monoxide levels become threatening to the average, healthy adult. An 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.
