Smoke detectors save lives Published Aug. 20, 2013 By Tech. Sgt. Andrew J. Kehl 18th Civil Engineer Squadron KADENA AIR BASE, Japan -- Whether awake or asleep, a properly installed and maintained smoke alarm is the only thing in one's home that can alert service members and their families of a fire 24 hours a day, seven days a week. According to the National Fire Protection Association, almost two-thirds of home fire deaths stem from fires in properties without working smoke alarms. To ensure an alarm is working and a home is safe, there are two ways the smoke alarm can be powered, by batteries or hardwired into a home's electrical system. If the smoke alarm is powered by a battery, it runs on a disposable 9-volt battery or a non-replaceable 10-year lithium, or "long-life," battery. A backup battery is usually present on hardwired alarms and may need to be replaced. These batteries must be tested on a regular basis and, in most cases, should be replaced at least once each year, except for lithium batteries. Residents should test their alarm system monthly, replace the batteries at least once a year and replace the entire alarm unit every eight to 10 years to ensure the safety of their homes. Kadena's fire department urges all residents to take a few minutes each month and test their smoke detectors. A working smoke alarm significantly increases the chances of surviving a deadly home fire; they are constantly on alert, scanning the air for fire and smoke.
