CHAPTER 1:
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 singlefamily 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.

IMPORTANT!
CAUTION!
WARNING!
This CO Alarm does not operate without a
working battery. Removing the battery, or
failure to replace it at the end of its service
life, removes your protection.
WARNING!
WARNING!
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.
WARNING!
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.
WARNING!
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 may consider using
warning devices which provide audible and
visual signals for carbon monoxide
concentrations under 30 ppm.
HOW YOUR CO ALARM WORKS
General Information
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, three colored
indicator lights, and an 85 dB alarm horn. It also
has a silence feature to temporarily quiet the
alarm horn.

CO ALARM IS IN ALARM.
Sensor has detected enough
CO to trigger an alarm. ALARM
light flashes RED rapidly and
horn sounds loudly. See
Chapter 3 for details on how
to respond to an alarm.
“ALARM-MOVE
TO FRESH AIR”
During an alarm, move
everyone to a source of fresh
air. Do NOT move the CO
Alarm!
CO ALARM SPECIFICATIONS
Gas Detection at Typical Temperature and
Humidity Ranges:
formulated to detect CO levels below 30 ppm
typically. UL tested for false alarm resistance to
Methane (500 ppm), Butane (300 ppm),
Heptane (500 ppm), Ethyl Acetate (200 ppm),
Isopropyl Alcohol (200 ppm) and Carbon
Dioxide (5000 ppm). Values measure gas and
vapor concentrations in parts per million.
Required Alarm Levels:
exposure at levels of 30% to 70% Relative
Humidity (RH):
• 400 ppm CO between 4 and 15 minutes
• 150 ppm CO between 10 and 50 minutes
• 70 ppm CO between 60 and 240 minutes
The unit is designed not to alarm when exposed
to a constant level of 30 ppm
for 30 days.
Audible Alarm:
Power:
Powered by 9V battery. Green light
flashes about twice a minute when device is
receiving battery power.
During Alarm:
red light flashes rapidly.
This CO alarm is designed to sound for up to
12 hours in alarm conditions, provided the
battery is fresh and installed correctly.

Standards:
Single and Multiple Station carbon monoxide
alarms UL2034.
According to Underwriters Laboratories Inc.
UL2034, Section 1-1.2: “Carbon monoxide
alarms covered by these requirements are
intended to respond to the presence of carbon
monoxide from sources such as, but not limited
to, exhaust from internal-combustion engines,
abnormal operation of fuel-fired appliances,
and fireplaces. CO alarms ar e intended to alarm
at carbon monoxide levels below those that
could cause a loss of ability to react to the
dangers of Carbon Monoxide exposure.” This
CO Alarm monitors the air, and is designed to
alarm before CO levels become life threatening.
This allows you precious time to leave the
house and correct the problem. This is only
possible if alarms are located, installed, and
maintained as described in this manual.

CHAPTER 2:
Installation
WHERE TO INSTALL
CO ALARMS
The Consumer Product Safety Commission
(CPSC) recommends the use of at least one
CO Alarm per household, located near the
sleeping area. For added protection, install
additional CO Alarms in each separate
bedroom, and on every level of your home.
If your bedroom hallway is longer than 40 feet,
install a CO Alarm at BOTH ends of the hallway.

GARAGE
In a Single-level Home:
• Install at least one CO Alarm near or
within each separate sleeping area.
• For added protection, install an additional CO Alarm at least 20 feet (6
meters) away from the furnace or fuel
burning heat source.
In a Multi-level Home:
• Install at least one CO Alarm near or
within each separate sleeping area.
• For added protection, install at least one
CO Alarm on each level of the home. If
you have a basement, install that CO
Alarm at the top of the basement stairs.
• For added protection, install an additional CO Alarm at least 20 feet (6
meters) away from the furnace or fuel
burning heat source.
In a Mobile Home:
• Install CO Alarms on inside walls ONLY.
Uninsulated outside walls and roofs of
mobile homes often transfer heat and
cold from outdoors.
