You Will Need

  • A carbon monoxide detector
  • Pencil
  • Screwdriver
  • Wall punch
  • Hammer
  • Batteries

Steps

  1. Step 1

    Research detectors

    Research which kind of carbon monoxide detector is right for your home. There are two popular kinds: Battery powered or AC plug-in powered.

  2. Battery-operated models are preferable because they can be placed near the ceiling, which is important because CO rises. But if you know you’ll never remember to change the batteries, go with an outlet detector.

  3. Step 2

    Choose location

    Decide where your detector will go. It should be away from fuel-burning appliances and at least 15 feet from heating or cooking units and humid areas, like the bathroom. Also, make sure no furniture or draperies cover the alarm.

  4. The Consumer Product Safety Commission recommends that the unit be placed near your bedroom, so it will wake you up if it goes off.

  5. Step 3

    Read installation instructions

    Take your product out of its packaging and read the installation instructions. If it's an AC outlet--powered unit, just plug it into the wall. If it's a battery-powered unit, it should come with screws and screw anchors.

  6. Step 4

    Mark wall w/ pencil

    Line up the unit with the wall, marking with a pencil where the screws need to go. Many carbon monoxide detectors have a separate twist-off base, making it easy to install the unit.

  7. Step 5

    Make holes in wall

    Now, use the wall punch to make a hole in the wall right over those dots. Be sure the holes are no bigger than your screw anchors; you'll want them to fit snugly.

  8. Step 6

    Tap anchors into holes

    With a hammer, lightly tap the anchors into the holes.

  9. Step 7

    Screw base to wall

    If you have a separate base, screw that into the wall. If the base does not detach, place the screws in the wall but do not tighten; make sure the detector fits over them and can be secured.

  10. Step 8

    Install battery

    Install the battery in your detector, then place it on the wall.

  11. Step 9

    Test detector

    Be sure to test it--not only so you'll know it works, but also so you'll know what it sounds like.

  12. Consumer Reports recommends detectors with warnings that become louder and faster as the CO increases.

  13. Step 10

    Mark calendar

    Mark on your calendar now to replace the batteries in a year. Then sleep easy, knowing you're safe!

  14. The symptoms of carbon monoxide poisoning are headache, shortness of breath, fatigue, dizziness, and nausea.
