Page 2: What You Should Know About Co
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. -
Page 3: Basic Safety Information
In general, install combination CO and Gas Alarms: • WHERE YOU CAN HEAR THE ALARM FROM ALL SLEEPING AREAS. • In or near bedrooms and living areas or wherever you suspect a gas or CO exposure is likely. • On each level of a multilevel home. IMPORTANT! Installation in an improper location can affect the sensitive electronic components in this alarm. -
Page 4: Recommended Location Of Alarms
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. -

Page 6: Operation & Alarm Characteristics
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: What To Do If The Alarm Sounds
IF THE CO ALARM SOUNDS: Operate SILENCE button; Call your emergency services, fire department or 911. Write down the number of your local emergency service here: 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: Testing & Maintenance
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 CSA 6.19-01 Standard. NEVER use vehicle exhaust! Exhaust may cause permanent damage and voids your warranty. -
Page 9: Co & Natural Gas Alarm Limitations
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. - Page 10 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.
