WHAT YOU SHOULD KNOW ABOUT CO

Carbon monoxide (CO) is an insidious poison. It is a colorless, odorless, tasteless gas. It is a

cumulative poison. Even low levels of CO have been shown to cause brain and other vital organ

damage in unborn infants with no effect on the mother.

The following symptoms are related to CARBON MONOXIDE POISONING and should be discussed

with

ALL members of the household:

MILD EXPOSURE

Slight headache, nausea, vomiting, fatigue (often described as "flu-like" symptoms).

MEDIUM EXPOSURE

Severe throbbing headache, drowsiness, confusion, fast heart rate.

EXTREME EXPOSURE

Unconsciousness, convulsions, cardiorespiratory failure, death.

Many cases of reported CARBON MONOXIDE POISONING indicate that victims are aware they

are not well, but they become so disoriented that 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.

Your combination alarm is designed to detect the toxic CO fumes that result from incomplete

combustion, such as those emitted from appliances, furnaces, fireplaces and auto exhaust.

This product is intended for use in ordinary indoor locations of family living units. It is not designed

to measure compliance with Occupational Safety and Health Administration (OSHA) commercial or

industrial standards. Individuals with medical problems may consider using warning devices which

provide audible and visual warnings for carbon monoxide concentrations under 30 ppm.

IMPORTANT CONSIDERATIONS

YOUR COMBINATION CO AND NATURAL GAS ALARM HAS BEEN DESIGNED WITH AN

END-OF-SERVICE LIFE ALARM WHICH WILL SOUND AFTER APPROXIMATELY 7 YEARS OF

OPERATION FROM INITIAL POWER UP.

NOTE: MANUFACTURER RECOMMENDS REPLACEMENT OF THIS ALARM 7 YEARS AFTER

DATE OF INSTALLATION.

WHAT YOU SHOULD KNOW ABOUT NATURAL GAS

Natural gas is a fossil fuel which consists primarily of methane. This common energy source is often

used for cooking, home heating and water heating. Natural gas is typically supplied through a main

utility line connected to your home. It is a highly flammable chemical compound. Although it happens

rarely, a natural gas leak can sometimes occur inside the home. This can be dangerous because it

increases the risk of explosion and fire.

Natural gas is odorless and colorless. When Mercaptan is added to natural gas as an odorant, it can

then be detected by smell. Although it can vary greatly, the typical level for detection of the gas by

smell is 25% of the lower explosion limit (LEL). People who have a diminished sense of smell may

not be able to rely on this safety mechanism. Therefore, installation of this alarm can be an important

tool to help protect you and your family. This alarm is calibrated to sound before 20% LEL Therefore,

it is possible that you may smell gas before the alarm is activated. If you are not sure which

gas your home uses, contact your utility company.

INSTALLATION RECOMMENDATIONS

Natural gas (methane) is typically supplied through a main utility line connected to your home.

Early warning is best achieved by the installation of alarms on all floors and areas of the household.

WHERE THIS ALARM SHOULD BE INSTALLED

• Install an alarm inside each bedroom where the occupant closes the door while sleeping.

• An alarm should be installed in any family living unit containing a fuel-burning appliance or fireplace

or having an attached garage.

• An alarm should be centrally located outside of each separate sleeping area in the immediate

vicinity of the bedrooms. Where bedrooms are separated and audibility of the alarm to occupants

within the bedroom area could be seriously impaired, more than one alarm could be needed.
