One of the least expensive investments that you will make in your home could ultimately prove to be the most valuable. Home smoke alarms are essential to possess in various spots through the dwelling to ensure the greatest protection. When selecting placement areas, consider putting smoke alarms in areas of high risk, such as the kitchen and garage. Each individual room should posses its own device, and any hallway or stair areas should have their own smoke detectors, too. Most importantly, check the batteries every three weeks to ensure they are functioning properly.
