While adding fire sprinklers to your home, you may want to consider other fire prevention and protective measures. Get your smoke alarms and CO alarms inspected and replaced, if needed. Add fire doors to vulnerable areas of your home. Inspect or purchase fire extinguishers. For exterior protection, consider fire-smart landscaping practices .

The National Fire Protection Association (NFPA) says you can place smoke detectors on either the ceiling or the wall, depending on the setup of your room. Since smoke rises, the ceiling makes sense, but if you go with a wall mounting, the alarm should be installed high up—no less than 12 inches from the ceiling. 

Concrete homes have better fire resistance because this material is highly resistant to fire and heat. But any paint, siding, windows, roofing, or other materials on a concrete home may still be flammable. Never try to stay in a building with a large, active fire or a wildfire approaching because this can still be deadly. However, building a fireproof home with concrete can better protect the structure against total destruction.

You can fireproof an existing door to some extent, but it's better to remove the old door and replace it with a fire-rated model. Anything dealing with extreme heat needs rigorous testing and a door you DIY fireproof will not undergo the same safety measures as a premade one. Consider a door with a rating of at least 30 minutes or more in residential areas.
