A. INTRODUCING the American Sensors Carbon

Monoxide Alarm

This Carbon Monoxide Alarm is an effective product for

detecting any build-up of carbon monoxide in your home.

Your new Alarm:

• Is easy to install

• Monitors for carbon monoxide continuously

• Sounds a loud alarm (85 dB) when it detects a hazardous

build-up of carbon monoxide

• Has a hazard level, or full, alarm

• Has a Test/Reset button so that you can test or reset at any

time

• Tests the electronics continuously

• Has a five-year limited warranty

B. What is carbon monoxide and why should you

be concerned?

Carbon monoxide is a dangerous, poisonous gas. It is often

referred to as the Silent

Killer because it has no

odor or taste and it

cannot be seen. The

presence of carbon

monoxide inhibits the

blood’s capacity to

transport oxygen

throughout the body,

which can eventually

lead to brain damage.

In any enclosed space

(home, office,

recreational vehicle or

boat) even a small accumulation of carbon monoxide can be

dangerous.

C. What are the potential sources of carbon

monoxide?

Although many products of combustion can cause discomfort

and adverse health effects, it is carbon monoxide (CO) that

presents the greatest threat to life.

CO is produced by the incomplete combustion of fuels such

as natural gas, propane, heating oil, kerosene, coal, charcoal,

gasoline or wood. The incomplete combustion of fuel can

occur in any device that depends on burning for energy or

heat such as furnaces, boilers, room heaters, hot water

heaters, stoves or grills and in any gasoline- powered vehicle

or engine (e.g., generator set or lawnmower). Tobacco smoke

also adds CO to the air you breathe.

When properly installed and maintained, your natural gas

furnace and hot water heater do not pollute your air space

with carbon monoxide. Natural gas is known as a “clean

burning” fuel because under correct operating conditions the

combustion products are water vapor and carbon dioxide,

which are not toxic. (Carbon dioxide (CO

) is also present in

the air we exhale and is necessary for plant life.) The

products of combustion are vented from furnaces and water

heaters to the outside by means of a flue duct or chimney.

Correct operation of fuel-burning equipment requires two key

conditions. There must be:

• An adequate supply of air for complete combustion

• Proper venting of the products of combustion from the

furnace through the chimney, vent or duct to the outside

Typical Carbon Monoxide Problems

1. Equipment problems, due to defects, poor maintenance,

damaged or cracked heat exchangers.

2. Collapsed or blocked chimneys or flues, dislodged,

disconnected or damaged vents.

3. Downdraft in chimneys or flues; this can also be caused by

very long or circuitous flue runs, improper location of flue

exhaust or wind conditions.

4. Improper installation or operation of equipment, chimneys

or vents.

5. Air tightness of house envelope results in a lack of air for

the combustion process.

6. Inadequate exhaust of space heaters or appliances.

7. Exhaust ventilation/fireplace competing for air supply.

D. Potential sources of carbon monoxide in your

home/office:

E. What are the possible symptoms of carbon

monoxide poisoning?

Carbon monoxide (CO) is odorless, colorless, tasteless and

very toxic. When inhaled, it produces an effect known as

chemical asphyxiation. Injury is due to the combining of CO

with the available hemoglobin in the blood, which lowers

the oxygen-carrying capacity of the blood. In the presence of

carbon monoxide, the body is quickly affected by oxygen

starvation.

The following symptoms are related to carbon monoxide

poisoning and should be discussed with all members of the

household so that you know what to look for:

Sensor vent

allows carbon

monoxide to

enter the

sensing circuit.

Alarm vent

Extreme Exposure (A-C): Unconsciousness, convulsions,

cardio-respiratory failure, death

Medium Exposure (D-G): Severe throbbing headache,

drowsiness, confusion, vomiting, fast heart rate

Mild Exposure (H-J): Slight headache, nausea, fatigue

(often described as “flu-like” symptoms)

Many cases of reported CARBON MONOXIDE

POISONING indicate that while victims are aware they are

not well, they become so disoriented they are unable to save

themselves by either exiting the building or calling for

assistance. Young children and household pets may be the

first affected. Exposure during sleep is particularly dangerous

because the victim usually does not awaken.

The amount of carbon monoxide in the air is measured as

ppm (parts per million). The graph below shows the

important relationship between carbon monoxide in the

air, exposure time and health effects.

For most people, mild symptoms generally will be felt after

several hours of exposure to 100 ppm of carbon monoxide.

Higher levels will lead to more severe symptoms or death.

F. Where should you install the Alarm?

Since carbon monoxide moves freely in the air, the suggested

location is in or as near as possible to sleeping areas of the

home. The human

body is most

vulnerable to the

effects of carbon

monoxide during

sleeping hours. For

maximum pro-

tection, a carbon

monoxide alarm

should be located

outside primary

sleeping areas or

on each level of

your home. In the figure above are suggested locations in the

home. The electronic sensor detects carbon monoxide,

measures the concentration and sounds a loud alarm before a

potentially harmful level is reached.

Some locations may interfere with the proper operation of

the alarm and may cause false alarms or trouble signals.

Do not place the Alarm in the following areas:

• Where the temperature may drop below 4.4°C (40°F) or

exceed 37.8°C (100°F).

• Near paint thinner fumes or household cleaning products.

Ensure proper ventilation when using these types of

chemicals.

• Within 1.5 m (5 feet) of any cooking or open flame

appliances such as furnaces, stoves and fireplaces.

• In exhaust streams from gas engines, vents, flues or

chimneys.

• Do not place in close proximity to an automobile exhaust

pipe; this will damage the Alarm.

G. How should you install the plug-in models?

Your American Sensors Carbon Monoxide Alarm is easy to

install to protect you and your family in your home, cottage,

cabin and office.

FOR PLUG-IN MODEL

CO800/CO800EL/CO910

Simply plug the Carbon Monoxide Alarm

into a standard 120 Volt AC wall outlet in

your home.

To provide maximum protection, please

allow one hour for your unit to initialize

after placement in electrical socket.

Do not use the alarm in an outlet that is

controlled by a wall switch.

If you have a double outlet, plug the unit

into the bottom outlet so that the top

outlet is available for other use.

To work properly, the unit must not be

blocked by furniture or draperies.

Hardwire Installation Instructions for Service Personnel

Simply attach your unit to any standard 120 Volt wiring system

utilizing the two wires and one of the electrical junction box

mounting plates provided. Follow local or federal electrical and

building code standards at all times.

Mount your Carbon Monoxide Alarm near the sleeping areas

of the home. To install the Alarm, please follow these steps:

1. Make sure the AC power to the junction box is turned off at

the Fuse Box or Service Panel before installation.

2. Install the appropriate round or box mounting plate

(supplied) to the junction box using the two 5/8 inch screws

(supplied). Be sure to pull the white (neutral) wire and

black (live) wire from the junction box through the

mounting plate center.

3. Connect the white wire (neutral) from the junction box to

the white wire of the Alarm using a twist-on wire connector

(supplied). The method is as follows: Strip both wires 1/2

inch. Keep the ends even. Hand twist the connector onto

the wires as tightly as possible.

Hold the connector and pull

each wire to make sure no wire

slips out. Make sure no bare

wire is exposed outside the

connector. Connect the black

wire (live) from the junction

box to the black wire of the

Alarm using a twist-on wire

connector and the same

method as above.

4. Check all connections and carefully push the wires and

wire connectors through the mounting plate and back into

the junction box.

5. Push the Alarm against the mounting plate with the 2

locator guides of the unit fitted into the slots of the

mounting plate.

6. While pushing forward, slide the

unit down until a clicking sound is

heard. The Alarm should now be

secured in place.

7. Turn the power back on at the

fuse box or service panel.

8. Your Alarm should be serviced by

Qualified Service Personnel only.

AC power should always be

turned off before servicing the

unit. To remove the Alarm from

its mounting plate, the locking mechanism (located in the

top-right corner) must be released as you slide the Alarm

unit upwards. This will expose your electrical wiring and

should be approached with extreme caution.
