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.

•

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) 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
information on carbon monoxide and your medical condition contact
your physician.

HOW YOUR CO ALARM WORKS

GENERAL INFORMATION

•

This CO Alarm does not operate without working batteries.
Removing the batteries, or failure to replace them at the end of their
service life, removes your protection.

A CO Alarm measures the CO levels in the air. It will alarm if CO levels rise
quickly (if the heat exchanger on your furnace breaks, for example), or if CO
is consistently present (a slow CO leak on a fuel-burning appliance).

This Carbon Monoxide Alarm features a permanently installed sensor and an
85 dB alarm horn. It also has a silence feature to temporarily quiet the alarm
horn.
