CHAPTER 1: Introduction
BASIC FEATURES
• Separate sensor and alarm to detect
smoke and CO. The two alarm systems
work independently.
• Powered by a single 9V alkaline or
lithium battery
• Flip-open battery door for easy battery
replacement
• Large, easy-to-use Test/Silence button
• Colored lights indicate battery status and
service needed.
The CO Alarm
The Carbon Monoxide (CO) Alarm measures
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 in your stove or water
heater).
• Features Solid-state Infrared Reservoir
(SIR) Sensor System
• “CO” alarm light flashes when
CO alarm is triggered
• Silence feature quiets alarm horn while
you take corrective action
The Smoke Alarm
The Smoke Alarm monitors the air for the
presence of combustion particles (produced
when something burns). When enough
combustion particles reach the smoke sensing
chamber, it triggers an alarm.
• Ionization Technology
• “SMOKE” alarm light flashes when
smoke alarm is triggered
• Silence feature quiets alarm horn in
response to unwanted alarms like those
caused by cooking smoke

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 combination Smoke and Carbon
Monoxide Alarm has two separate alarms.
The CO alarm is not designed to detect fire
or any other gas. It will only indicate the
presence of carbon monoxide gas at the
sensor. Carbon monoxide gas may be
present in other areas. The Smoke Alarm will
only indicate the presence of smoke that
reaches the sensor. The smoke alarm will
not sense gas, heat or flames.
This smoke/CO alarm is approved for use in
single-family residences. It is NOT designed for
marine or RV use.
This device is not intended to alert hearing
impaired residents. Smoke alarms specifically
designed for the hearing impaired, which featur e
devices like flashing strobe lights, are available
to alert the hearing impaired in case of fire.

The Carbon Monoxide Alarm (continued)
According to Underwriters Laboratories Inc.
UL2034, Section 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. Carbon monoxide alarms are
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.
This CO alarm is designed to alert you to
a potentially dangerous build-up of CO over
time. It cannot fix a CO problem, and it
cannot identify a specific source of CO.
The company shall not be obligated to pay
for any carbon monoxide investigation or
service call conducted by a Fire Department,
or licensed investigator or repairman,
arranged by the homeowner in response to
an alarm.

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.

CHAPTER 2: Installation
WHERE TO INSTALL
THIS ALARM
Minimum coverage for smoke alarms, as
recommended by the National Fire Protection
Association (NFPA), is one smoke alarm on
every floor, in every sleeping area, and in every
bedroom (See Chapter 8 for details on the
NFPA recommendations).
The Consumer Product Safety Commission
(CPSC) recommends the use of at least one
CO alarm per household, located near the
sleeping area.
OTE:
For added protection, install an additional
CO alarm at least 15 feet (5 meters) away from
the furnace or fuel burning heat source.
In general, install combination
Smoke and Carbon Monoxide Alarms:
• On every level of your home, including
finished attics and basements.
• Inside every bedroom, especially if
people sleep with the door partly or
completely closed.
• In the hall near every sleeping area. If
your home has multiple sleeping areas,
install a unit in each. If a hall is more than
40 feet (12 meters) long, install a unit at
each end.
• At the top of first-to-second floor stairs.
• At the bottom of the basement stairs.
• For additional coverage, install alarms in
all rooms, halls, and storage areas, wher e
temperatures normally remain between
40˚F and 100˚F (4˚C and 38˚C).
In a Mobile Home:
• Install alarms on inside walls ONLY!
Uninsulated outside walls and roofs of
mobile homes often transfer heat and
cold from outdoors.

N
Recommended Placement
• When installing on the wall, the smoke
alarm should be placed between 4 inches
(102 mm) and 12 inches (305 mm) from
the wall/ceiling line.
• When installing on the ceiling, place the
alarm as close to the center as possible.
• In either case, install at least 4 inches
(102 mm) from where the wall and ceiling
meet. See “Avoiding Dead Air Spaces”
on page 7 for more information.
OTE:
For any location, make sure no door or other
obstruction could keep carbon monoxide or
smoke from reaching the alarm.

WHERE NOT TO INSTALL
THIS ALARM
Do NOT locate this smoke/CO alarm:
• In garages, kitchens, furnace rooms, crawl
spaces and unfinished attics. Avoid
extremely dusty, dirty or greasy areas.
• Closer than 20 feet (6 meters) from a furnace or other fuel burning heat source, or
fuel burning appliances like a water heater.
• Where combustion particles (formed when
something burns) are produced. Avoid
poorly ventilated kitchens, garages, and
furnace rooms. Keep this smoke/CO alarm
at least 20 feet (6 meters) from sources of
combustion particles (stove, vehicle,
furnace) whenever possible.
• Within 5 feet of any cooking appliance.
In air streams near kitchens. Air currents
can draw cooking smoke into the smoke
sensor and cause unwanted alarms.
• In extremely humid areas. This alarm should
be at least 10 feet (3 meters) from a shower,
sauna, humidifier, vaporizer, dishwasher,
laundry room, utility room, or other source
of high humidity.
• In direct sunlight.
• In turbulent air, like near ceiling fans or open
windows. Blowing air may prevent CO or
smoke from reaching the sensors.

Do NOT locate this smoke/CO alarm:
• Where the temperatures are regularly
below 40˚ F (4˚C) or above 100˚ F (38˚ C)
including unheated buildings, outdoor
rooms, porches, or unfinished attics or
basements. Extreme temperatures may
shorten component or battery life.
• In insect infested areas. Insects can clog
the openings to the sensing chamber.
• Less than 12 inches (305 mm) away from
fluorescent lights. Electrical “noise” can
interfere with the sensor.
Avoiding Dead Air Spaces
“Dead air” spaces may prevent smoke from
reaching the smoke alarm. To avoid dead air
spaces, follow installation recommendations:
On ceilings,
the center of the ceiling as possible. If this is
not possible, install the smoke alarm at least 4
inches (102 mm) from the wall or corner.
On a peaked, gabled, or cathedral ceiling,
the first smoke alarm within 3 feet (0.9 meters)
of the peak of the ceiling, measured
horizontally. Additional smoke alarms may be
required depending on the length, angle, etc. of
the ceiling's slope. Refer to NFPA 72 for details
on requirements for sloped or peaked ceilings.
For wall mounting
codes), the smoke alarm should be placed
between 4 inches (102 mm) and
install smoke alarms as close to
install
(if allowed by building
12 inches (305 mm) from the wall/ceiling line,
below typical “dead air” spaces.
