INTRODUCTION
BASIC SAFETY INFORMATION
• Dangers, Warnings, and Cautions alert you to important
operating instructions or to potentially hazardous situations.
Pay special attention to these items.
• THIS IS NOT A SMOKE ALARM! This CO Alarm is designed to
detect carbon monoxide from ANY source of combustion. It is
NOT designed to detect smoke, fire, or any other gas.
• This CO Alarm is approved for use in single-family residences.
It is NOT designed for marine or RV use.
• This CO Alarm will only indicate the presence of carbon
monoxide gas at the sensor. Carbon monoxide gas may be
present in other areas.
• The Silence 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.
• This CO Alarm should receive continuous 120VAC, 60 Hz, pure
sine wave electrical power. Do not use in an extension cord or
outlet controlled by a dimmer or switch.
• NEVER ignore your Carbon Monoxide Alarm if it alarms. Refer
to “If Your CO Alarm Sounds” for more information. Failure to
do so can result in injury or death.
• 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.
• This product is intended for use in ordinary indoor locations of
family living units. It is not designed to measure CO levels in
compliance with Occupational Safety and Health Administration
(OSHA) commercial or industrial standards. Individuals with
medical conditions that may make them more sensitive to
carbon monoxide may consider using warning devices which
provide audible and visual signals for carbon monoxide concen-
trations under 30 ppm. For additional information on carbon
monoxide and your medical condition contact your physician.
HOW YOUR CO ALARM WORKS
GENERAL INFORMATION
Leave your CO Alarm plugged in year-round. CO problems can
occur any time during the year, and this Alarm can only alert you if it
is plugged in and receiving power.
This CO Alarm is intended for use in a standard, unswitched 120V AC
wall outlet. It is not intended for use in extension cords, power strips, or
outlets controlled by a switch or dimmer. These may not provide contin-
uous power to the unit. When fully powered, the unit samples the air and
takes a new reading about every second. A microchip inside the unit
stores each reading, and remembers the levels of CO it has been
exposed to over time. The Alarm sounds when it has been exposed to a
“critical” level of CO (measured in parts per million or “ppm”) within a
specified time (measured in minutes). This CO Alarm features a perma-
nently installed sensor, an indicator light, and an 85dB alarm horn. It also
has a Silence Feature to temporarily quiet the alarm horn.
MALFUNCTION WARNING
This unit performs self-diagnostic tests approximately every second.
If the Alarm malfunctions, it should be replaced immediately.
