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.

In general, install combination CO and Gas Alarms:

WHERE YOU CAN HEAR THE ALARM FROM ALL SLEEPING AREAS.

In or near bedrooms and living areas or wherever you suspect a gas or CO exposure is likely.

On each level of a multilevel home.

IMPORTANT!

Installation in an improper location can affect the sensitive electronic components in this alarm. Please review WHERE THIS ALARM SHOULD NOT BE INSTALLED (see Page 3).

Not suitable for installation in hazardous locations as defined in the National Electric Code. This alarm will detect natural gas primarily and carbon monoxide secondarily. Natural gas events will always take precedence over carbon monoxide events. The word "gas" will be used to specifically refer to natural gas.

When on AC power, this alarm is designed to act as a continuous monitor. It is not designed for use as a short-term testing device to perform a quick check for the presence of CO or gas.

BASIC SAFETY INFORMATION

This combination Carbon Monoxide and Natural Gas alarm has two separate alarms. This alarm is not designed to detect fire or any other gas. Carbon monoxide and natural gas may be present in other areas. The CO and Natural Gas Alarm will only indicate the presence of CO or natural gas which reaches the sensor. The CO and Natural Gas Alarm is not designed to sense smoke, heat or flames.

Do not paint the alarm. Paint may clog the openings to the sensing chambers and prevent the unit from operating properly.

Do not stand too close to the unit when the alarm is sounding. It is loud to wake you in an emergency. Exposure to the horn at close range may harm your hearing.

Make sure the alarm is not receiving excessively noisy power. Examples of noisy power could be major appliances on the same circuit, power from a generator or solar power, light dimmer on the same circuit or mounted near fluorescent lighting. Excessively noisy power may cause damage to your alarm.

Find the pair of self-adhesive labels included with this CO and Gas Alarm.

On each label, write in the phone number of your emergency responder (such as 911) and a qualified appliance technician.

Place one label near the CO and Gas Alarm and the other label in the "fresh air" location you plan to go to if the alarm sounds.

This alarm cannot be operated from power derived from a square wave, modified square wave or modified sine wave inverter. These types of inverters are sometimes used to supply power in off-grid installations, such as solar or wind derived power sources. These power sources may produce high peak voltages which will damage the alarm.

This unit should receive continuous electrical power. (The battery is meant for emergency backup only.) Choose an outlet where it can't be accidentally unplugged or switched off by children. Keep small children away from the unit. Teach them not to play with it or unplug it. Explain what the alarms mean.

Do not plug this alarm into an outlet controlled by a dimmer or switch or ground fault circuit interrupter.

The test sequence lasts for approximately 8 seconds after the test button is pressed. The alarm will then test itself for proper operation. The red LED indicator will simultaneously flash in sync with the horn alarm patterns, for example, 1 beep, 1 second pause, 4 beeps, 5 second pause. When testing the alarm, have someone else check that the alarm can be heard easily from the sleeping areas. The unit should be located where it can wake you if it alarms at night.

RECOMMENDED PLACEMENT:

NOTE: For any location, make sure no door or other obstruction could prevent the carbon monoxide or gas from reaching the alarm.

WHERE THIS ALARM SHOULD NOT BE INSTALLED

To avoid causing damage to the unit, to provide optimum protection, and to prevent unnecessary alarms. Do NOT locate this alarm:

In garages, kitchens, crawl spaces and unfinished attics. Avoid extremely dusty, dirty or greasy areas. Installation in these areas could lead to nuisance alarms, may expose the sensor to substances which could damage or contaminate it, or the alarm may not be heard by people in other areas of the home, especially if they are sleeping.

In the garage, vehicle exhaust can contain some carbon monoxide. These levels are higher when the engine is first started. Within hours of starting a vehicle and backing it out of the garage, the levels present over time can activate the alarm and become a nuisance.

In the kitchen, some gas appliances can emit a short burst of CO or gas upon startup. This is normal. If your CO and Gas Alarm is installed too close to these appliances, it may alarm often and become a nuisance.

Keep alarms at least 20 feet (6m) from the sources or combustion particles (stove, furnace, water heater, space heater), if possible. In areas where a 20 foot (6m) distance is not possible (in modular, mobile or smaller homes for example), it is recommended the alarm be placed as far from these fuel-burning sources as possible. The placement recommendations are intended to keep these alarms at a reasonable distance from a fuel-burning source and reduce "unwanted" alarms. Unwanted alarms can occur if an alarm is placed directly next to a fuel-burning source. Ventilate these areas as much as possible. If you must install the alarm near a cooking or heating appliance, install at least 5 feet (1.5m) from appliance.

Curtains or heavy furniture may prevent CO or gas from reaching the sensor.

Less than 12 inches (306mm) away from fluorescent lights. Electrical noise can interfere with the sensor.

In extremely humid areas. This alarm should be at least 10 feet (3m) from a bath or shower, sauna, humidifier, vaporizer, dishwasher, laundry room, utility room or other source of high humidity.

In very cold or very hot environments or in unheated buildings or outdoor rooms where the temperature can go below or above the operating range of the alarm. Temperature limits for proper operation are 40o to 100oF (4.4o to 37.8oC).

In turbulent air, such as near ceiling fans, heat vents, air conditioners, fresh air returns or open windows. Blowing air may prevent CO from reaching the sensors.
