Smoke alarms are either hardwired into a home's electrical system or powered by a battery. Hardwired smoke alarms usually have a backup battery to keep the alarm functioning if there is a power failure. All batteries should be maintained and replaced in accordance with manufacturer's guidance, Medford Fire-Rescue said in a news release.

According to the United States Fire Administration, each year in the United States about 2,500 people die in home fires. According to the National Fire Protection Association, two-thirds of fire deaths occur in homes with no working smoke alarms present. Properly placed and maintained smoke alarms cut the chance of dying in a home fire by 50 percent, fire officials report.
