The DXS-80 is a carbon monoxide (CO) alarm with a built-in transmitter

PRODUCT DESCRIPTION

designed for use with Linear’s DXS and DX Format receivers. The detector gives warning to alert against both the acute and chronic effects of CO poisoning. When carbon monoxide is detected, the alarm sounds a loud local alarm. When the local alarm sounds, the built-in transmitter sends a digitally coded wireless signal to its companion receiver every 20 seconds until the air has cleared and the detector is restored. The local alar m can be silenced once by pressing the TEST/RESET button. The transmitter will continue to send an alarm signal every 20 seconds. After 7 minutes, the alar m will sound again if there is still an unsafe CO concentration level. The reset function can be used only once for each alarm occurrence. The DXS transmitters are precoded at the factory to one of over a million possible unique system codes, so no ﬁeld coding is required. Receivers must be programmed to the transmitter’s code before system testing and operation. Refer to the receiver’s instr uctions for details on programming. The unit is powered by one 3-volt lithium battery. The battery is supplied with the transmitter and can power the unit for more than one year. If the battery voltage drops below a preset level the alarm will sound a low battery chirp every 45 seconds and a low battery signal will be sent to the receiver (some receivers can report low battery, others cannot). When the detector reaches the end of its serviceable life (after about 6 years) a permanent trouble condition will occur and cannot be reset. Maintenance: Occasionally clean the outside casing with a cloth. Ensure that the holes on the front of the alarm are not blocked with dirt and dust. Do not paint, and do not use cleaning agents, bleach, or

polish on the detector.

4 After following steps 1 - 3, if your alarm reactivates within a 24-hour period, repeat steps 1 - 3 and call a qualiﬁed technician

to investigate for sources of CO from fuel burning equipment and appliances, and inspect for proper operation of this equipment. If problems are identiﬁed during this inspection, have the equipment serviced immediately. Note any combustion equipment not inspected by the technician and consult the manufacturers’ instructions or contact the manufacturers directly for more information about CO safety and this equipment. Make sure that motor vehicles are not and have not been operating in an attached garage or adjacent to the residence.

IMPORTANT INFORMATION

1.0 WHAT YOU SHOULD KNOW ABOUT CO

Carbon monoxide (CO) is an insidious poison. It is a colorless, odor less and 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 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. Also, young children and household pets may be the ﬁrst affected. Your CO 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. A CO Alarm is NOT A SUBSTITUTE for other combustible gas, ﬁre or smoke alar ms. This carbon monoxide alarm is designed to detect carbon monoxide gas from ANY source of combustion.

CAUTION: ☞ This alarm will only indicate the presence of carbon monoxide gas at the sensor. Carbon monoxide gas may be present in other areas. WARNING: ★ 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 signals for carbon monoxide concentrations under 30 ppm.

2.0 IMPORTANT CONSIDERATIONS

2.1 • The DXS-80 has been designed to operate for six years with

regular maintenance.

2.2 • Never disconnect the battery to silence an alarm. The alarm will automatically sense when the level of CO in the air falls below the danger level. You should stay outside the residence in fresh air until the alarm is silenced. When the alarm sounds, do not stand too close to the alarm. The sound produced by the alarm is loud because it is designed to awaken a person in an emergency. Prolonged exposure to the alarm at a close distance may be harmful to your hearing.

NOTE: ☞ Manufacturer strongly recommends replacement of alarm six years after date of purchase. Under no circumstances should the alarm be used (7) years after the date of purchase.

3.0 DEVELOPING YOUR OWN CO SAFETY PLAN

This CO alarm can quickly aler t you to the presence of CO, it cannot prevent toxic CO emissions. Please note that there are hazards against which CO detection may not be effective, such as gas leaks or explosions. The ultimate responsibility for protection against toxic CO fumes rests solely on you. Installing CO detectors is just the ﬁrst step in protecting your family from toxic CO poisoning. We also suggest that you create an effective, comprehensive safety program as outlined below.

3.1 • Install CO detectors properly following the instructions in this manual.

3.2 • Develop a family escape plan and practice it with your entire

family, especially small children.

Draw a ﬂoor plan of your home and ﬁnd two ways to exit from ✓ each room. There should be one way to get out of each bedroom without opening the door. Make sure that all occupants know what the CO alarm signal ✓ means and how they must exit the residence by themselves if necessary. Decide on a meeting place a safe distance from your house and ✓ make sure all occupants understand where they should go and wait if there is a dangerous CO condition. Conduct CO safety dr ills at least every 6 months to make sure ✓ that everyone, even small children, know what to do in order to escape safely. Know where to go to call the Fire Depar tment from outside your ✓ residence.

NOTE: ☞ This unit is designed to detect carbon monoxide (CO) entering its sensing chamber. It does not sense combustible gas (such as natural gas, propane or butane), heat, smoke or ﬂames.

4.0 IMPORTANT: WHAT YOUR CO ALARM CAN AND CANNOT DO

4.1 • This CO alarm is designed for use within a single residential

living unit only. In a multi-family building, the alarm may not provide early war ning for residents if it is placed outside of the residential units, such as on outside porches, in corridors, lobbies, basements, or in other apartments. In multi-family buildings, each residential unit should have detectors installed as previously indicated.

4.2 • When properly located, installed, and maintained, this CO alarm is designed to provide early war ning of developing poisonous CO conditions at a reasonable cost. This alarm monitors the air, and when it senses CO, it activates its built-in alarm. It can provide precious time for you and your family to escape from your residence before CO can ser iously injure or kill. However, such an early warning is possible only if the alarm is located, installed, and maintained as speciﬁed in the Owner’s Manual.

WARNING: ★ The DXS-80 CO Alarm is not designed for marine, aircraft, automobile or RV use.

5.0 INSTALLING THE DXS-80 FOR RESIDENTIAL USE

If bedroom doors are usually closed at night, alarms should be placed in each bedroom as well as in the common hallway between them. CO alarms may not sense CO on a different level of a residence or building. For example, a second ﬂoor alarm may not sense a CO leak on the ﬁrst ﬂoor or in the basement. Therefore, alarms should be placed on every level of a residence or building. If the alarm is located outside of a bedroom, it may not wake up a sound sleeper, especially if the bedroom door is closed or only partly open. If the alarm is located on a different level of the residence than the bedrooms, it is even less likely to wake up people sleeping in the bedroom. Installing CO alarms may qualify you for lower homeowner’s insurance rates, but CO alarms are not a substitute for insurance. Homeowners and renters should continue to insure their lives and property.

5.1 • RECOMMENDATIONS One of the most important considerations in any CO alarm system is the location of the alarms. Statistics of the National Fire Protection Association (NFPA) show that most of the fatal CO occurrences happen at night while people are sleeping. Early warning of CO is best achieved by the correct installation of CO alarms. Placement of an alarm in a garage may cause an alarm due to CO from automotive exhaust.

5.2 • RECOMMENDED MOUNTING LOCATIONS Put a CO alarm inside each bedroom where the occupant closes the door while sleeping. A closed door can block particulate smoke, but CO gas is likely to get through.

5.3 • This CO alarm must be mounted on the wall or ceiling.

5.4 • LOCATIONS TO AVOID Placing units where they will not operate

properly causes nuisance alarms. To avoid nuisance alarms, do not place units:

Within 5 feet (1.5m) of any cooking appliance or furnace. ✓ Near an open window or door, because the fresh air entering the ✓ opening may delay CO from reaching the alarm. In damp or very humid areas or next to bathrooms with showers ✓ or tubs. Install detectors at least 10 feet (3 meters) away from bathrooms. 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 32° F to 100° F (4.4° C to 37.8° C). Good ventilation is recommended when household cleaning ✓ supplies or similar contaminants are used.

5.5 • SOME CONDITIONS WHICH CAN RESULT IN TEMPORARY CO SITUATIONS:

5.5.1 • Excessive spillage or reverse venting of fuel burning appliances caused by outdoor ambient conditions, such as:

a. Wind direction and/or velocity, including high gusts of wind. Heavy air in the vent pipes (cold/humid air with extended periods between cycles).

b. Negative pressure differential resulting from the use of exhaust fans.

c. Simultaneous operation of several fuel burning appliances competing for limited internal air.

d. Vent pipe connections vibrating loose from clothes dryers, furnaces, or water heaters.

e. Obstructions in or unconventional vent pipe designs which can amplify the above situations.

5.5.2 • Extended operation of unvented fuel burning devices (range, oven, ﬁreplace, etc.)

5.5.3 • Temperature inversions, which can trap exhaust gasses near the ground.

5.5.4 • Car idling in an open or closed area garage, or near a home.
