Page 3: 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 4 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 SMOKE, CO AND NATURAL GAS ALARM SHOULD BE INSTALLED •...

Page 10: Operation, Testing & Maintenance
OPERATION, TESTING & MAINTENANCE OPERATION: The alarm is operating once the AC power is connected and turned on. When products of combustion are sensed, the alarm sounds a loud alarm which continues until the air is cleared. This alarm incorporates the NFPA recognized horn signal for evacuation. During alarm mode, the horn produces three beeps followed by a two second pause and then continually repeats.
Page 11: Co & Smoke Alarm Silence Feature
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.
