The National Fire Protection Association

According to the National Fire Protection Association (NFPA), smoke alarms should be installed on every level of your home, including the basement and installed inside of every bedroom and outside of each sleeping area.  For example, a home that is two stories and has three bedrooms should have five smoke alarms. Homes that have a set number of hardwired alarms can still place more battery-operated smoke alarms throughout the house. There is no such thing as having too many smoke alarms in your home! Just make sure they are properly placed within each room.

Where to Place Alarms on the Ceiling

In order to benefit from smoke alarms in your home, they need to be properly installed in each room. In the kitchen, battery operated smoke detectors should be installed at least 10 feet away from cooking appliances to minimize the number of false alarms. Smoke rises, so smoke alarms should be placed high on walls or ceilings.If you are installing your battery-operated smoke alarm on a wall, the top of the alarm should not be installed more than 12 inches from the ceiling. Keep in mind that alarms should not be placed too close to vents or windows in order for them to properly work.
