Customer Reviews For The 10-Year Battery Carbon Monoxide Alarm with Digital Temperature Display

Place carbon monoxide alarms near or within each separate sleeping area so the alarm can be heard while occupants are asleep. For added protection, install an alarm in every bedroom and on every level of the home.

• Single-level homes: Place at least one CO alarm near or within each separate sleeping area.
• Multi-level homes: Place an alarm near each sleeping area and on every floor. If the home has a basement, place an alarm at the top of the basement stairs.
• Long bedroom hallways: If a hallway is longer than 40 feet, place a CO alarm at both ends.
• Mobile homes: Place CO alarms near interior walls only. Uninsulated exterior walls and roofs can transfer outdoor heat and cold.

Keep the alarm at least 20 feet from furnaces, water heaters and other fuel-burning heat sources, and at least 5 feet from cooking appliances. It should also be at least 10 feet from bathrooms, showers, saunas, humidifiers, dishwashers, laundry rooms and other sources of high humidity.

Do not place the alarm in garages, kitchens, furnace rooms or extremely dusty, dirty or greasy areas. Avoid unfinished attics, crawl spaces, porches and other locations where temperatures may fall below 40°F or rise above 100°F. The alarm should also be kept away from ceiling fans, heating and cooling vents, air returns, open windows and other sources of turbulent air that could prevent carbon monoxide from reaching the sensor.

Always follow the placement instructions included with the alarm and any applicable local carbon monoxide alarm requirements.
