First Alert Carbon Monoxide Detector Installation

In the United States, about 170 people die every year from carbon monoxide poisoning, according to the U.S Consumer Product Safety Commission. In general, carbon monoxide is a poisonous gas without color and odor. Defective and inefficient internal combustible appliances such as portable generators, gas log fireplaces and gas-fired furnaces will produce carbon monoxide fumes. Many states will require every level in the building and near the sleeping quarters to install carbon monoxide detectors. Here are the steps on how to install it.

You will need:

  1. Hammer.
  2. Drill with 3/16 drill bit
  3. Pencil.
  4. Flathead screwdriver.


  1. First, open the battery hatch over on the First Alert carbon monoxide detector before inserting the batteries. Make sure to follow the diagram in the hatch compartment for proper placement for each of the battery. When the replacement finishes, close the battery hatch over.
  2. Then, turn over the alarm. Press the “test” button until the alarm sounds, and after a few beeps the alarm will turn off automatically. Open the small bag of screws anchors and screws, which are provided together with the First Alert carbon monoxide detector. Determine the place for the device. However, avoid yourselves from placing the alarm closer than 4 inches from where the walls meet the ceiling, which is recommended by First Alert.
  3. Next, unfold the mounting guide template from the package and place it against the wall of our desired location. Mark the inside of the template mounting holes using a pencil. Remove the template and drill the holes at your pencil marks.
  4. Place the plastic screws anchors into the drilled holes. If needed, tap the screw anchors with a hammer lightly. Insert the screws into the anchors using a flathead screwdriver by allowing the screws to project from the wall 1/8 inch.
  5. Finally, slide the back of the First Alert carbon monoxide detector onto the screws. Continue to slide until the screws enter the mounting brackets.
