Step 2 - Determine the number of smoke detectors needed - Choose how many detectors will be installed. Follow manufacturers recommendations in this area. Remember that you want at least one detector for each occupied bedroom.

Step 3 - Locate the areas - Choose the place where your detectors will be installed. Follow manufacturers recommendations. As a rule of thumb the higher you mount the detectors the better. Smoke rises so the higher the detector is mounted the sooner it will alarm. Typically you should place your alarm 6-12 inches from the area where a wall meets a ceiling because these areas create "dead spots" that may delay an alarm. Also don't put smoke detectors near a window, door, under an air conditioning vent, or other area where the air may be lost or the presence of smoke may be obscured. Also putting smoke detectors in kitchens, or bathrooms because steam from cooking or showers, cooking, and etc. can cause false triggers. Areas with fumes such as those from from paint, solvents, chemicals, or gasoline can cause a false trigger.

Step 4 - Prepare the Area - Set up the ladder just below the area where the detector is to be installed. Note: Make sure that the ladder is a safety ladder and is stable and safe so you do not fall.

Step 5 - Prepare Yourself - Put on your goggles and breathing mask and get the tools you need for the next step.

Step 6 - Remove the Old Detector Body (Replacement Only) - Detectors typically come in two parts, the body and the mount. The body can typically be removed by turning the body of the detector freeing it from the mount.

Remove them carefully taking particular care to prevent the screws from stripping out the slots in the head of the screw. Also remember that the mount may move and or fall once several of the screws have been removed so keep one hand on the mount to prevent it from moving.

Step 8 - Follow the Manufacturer Instructions - Most detectors simply require the screws be replaced in the mount but each detector can vary slightly in installation so follow the instructions provided by the manufacturer.

Step 9 - Test The Detector - Once you have finished the installation check the detector to make sure that it is working.

Step 10 - Repeat the process - Repeat the process for each detector that needs to be installed or replaced.
