The UL 2034 standard for residential carbon monoxide (CO) alarms does not
permit listed CO alarms to automatically display or alarm at CO levels below
30 ppm. The Defender LL6270 is designed to provide added protection for
older adults, pregnant women, young children, and persons with medical
conditions who may be more vulnerable to lower CO levels, and is not UL
listed.
When installed in residential applications, this monitor should
supplement, not replace, a UL listed CO alarm.

  • Page 7 4. INFORMATION ABOUT CARBON MONOXIDE WHAT IS CARBON MONOXIDE? Carbon monoxide (CO) is a highly toxic, invisible, odorless, tasteless gas. HOW IS CO GENERATED? Carbon monoxide is generated through incomplete combustion of fuel in various appliances. Poorly ventilated furnaces, boilers, water heaters, space heaters, fireplaces and wood burning stoves are the major cause of high CO levels in a building.
  • Page 8 5. RECOMMENDED LOCATION OF MONITORS CO poisoning can occur anywhere in the building. CO monitors should be installed on an interior wall, five feet off the floor, and on every heated and air conditioned level of the building. At the minimum, install CO monitors: 1.

  • Page 9: Locations To Avoid

    6. LOCATIONS TO AVOID NEAR A COOKING AREA: Do not install the monitor within five feet of any cooking appliances. CO may be generated during cooking and cause nuisance alarms. Also, cooking grease buildup can lead to monitor failure. Monitor near commercial cooking area should be cleaned at least once a month, or more frequently if necessary.
