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 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 cannot operate without continuous electricity. It does
not operate during a power failure.
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 work-
ing 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) commer-
cial 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 concentrations under 30 ppm. For additional infor-
mation 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 continuous power to
the unit. 
When fully powered, it 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 unit goes into alarm mode
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 Carbon Monoxide Alarm features a permanently installed sensor, three
colored indicator lights, and an 85dB alarm horn. It also has a Silence Feature
to temporarily quiet the alarm horn.
