In new construction AC and AC/DC smoke alarms MUST be interconnected to meet NFPA recommendations.

WHAT IS CO?

O is an invisible, odorless, tasteless gas produced when fossil fuels do not

C burn completely, or are exposed to heat (usually fire). Electrical appliances

pically do not produce CO.

hese fuels include:Wood, coal, charcoal, oil, natural gas, gasoline, kerosene,

and propane.

mon appliances are often sources of CO. If they are not properly main-

Com tained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real danger now that homes are more energy efficient. “Air-tight”

s with added insulation, sealed windows, and other weatherproofing

home can “trap” CO inside.

SYMPTOMS OF CO POISONING

These symptoms are related to CO POISONING and should be discussed

ith ALL household members.

Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like” symptoms).

edium Exposure:Throbbing headache, drowsiness, confusion, fast heart rate.

M Extreme Exposure: Convulsions, unconsciousness, heart and lung failure.

Exposure to Carbon Monoxide can cause brain damage, death.

This CO Alarm measures exposure to CO over time. It alarms if CO levels

e extremely high in a short period of time, or if CO levels reach a certain

inimum over a long period of time. The CO Alarm generally sounds an alarm

m before the onset of symptoms in average, healthy adults. Why is this important?

cause you need to be warned of a potential CO problem while you can still

eact in time. In many reported cases of CO exposure, victims may be aware

r that they are not feeling well, but become disoriented and can no longer react well enough to exit the building or get help. Also, young children and pets may

he first affected.The average healthy adult might not feel any symptoms

be t when the CO Alarm sounds. However, people with cardiac or respiratory problems, infants, unborn babies, pregnant mothers, or elderly people can

e quickly and severely affected by CO. If you experience even mild

be mor symptoms of CO poisoning, consult your doctor immediately!

FINDING THE SOURCE OF CO AFTER AN ALARM

arbon monoxide is an odorless, invisible gas, which often makes it difficult to

C locate the source of CO after an alarm. These are a few of the factors that can make it difficult to locate sources of CO:

Because CO may dissipate by the time an investigator arrives, it may be difficult to locate the source of CO.

HERE TO INSTALL THIS ALARM, Continued

or CO Alarms,the National Fire Protection Association (NFPA) recommends

hat a CO Alarm should be centrally located outside of each separate sleeping

ea in the immediate vicinity of the bedrooms. For added protection, install

ar additional CO Alarms in each separate bedroom, and on every level of your home.

NOTE: For added protection, install an additional Smoke/CO Alarm at least

5 feet (4.6 meters) away from the furnace or fuel burning heat source where

ble. In smaller homes or in manufactured homes where this distance

possi cannot be maintained, install the Alarm as far away as possible from the

urnace or other fuel burning source. Installing the Alarm closer than 15 feet (4.6

ters) will not harm the Alarm, but may increase the frequency of unwanted

me alarms.

RECOMMENDED RESIDENTIAL PLACEMENT

• When installing on the wall, the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the

all/ceiling line.

• When installing on the ceiling, place the alarm as close to the center as

ble.

possi In either case, install at least 4 inches (102 mm) from where the wall and

• ceiling meet. See “Avoiding Dead Air Spaces” 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 THIS ALARM SHOULD NOT BE INSTALLED

o NOT locate this Smoke/CO Alarm:

Avoid extremely dusty, dirty or greasy areas.

•

• Where combustion particles are produced. Combustion particles form

hen something burns.Areas to avoid include poorly ventilated kitchens,

w garages, and furnace rooms. Keep units at least 20 feet (6 meters) from the sources of combustion particles (stove, furnace, water heater, space heater)

ble. In areas where a 20-foot (6 meter) distance is not possible – in

if possi modular, mobile, RVs, or smaller homes, for example – it is recommended the Smoke Alarm be placed as far from these fuel-burning sources as

ble. The placement recommendations are intended to keep these

possi Alarms at a reasonable distance from a fuel-burning source, and thus reduce “unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm is

laced directly next to a fuel-burning source. Ventilate these areas as much
