Power Source info
Power Source Smoke alarms are powered by battery or by your home's electrical system. If the smoke alarm is powered by battery, it runs on either a disposable 9-volt battery or a non-replaceable 10-year sealed lithium battery. Alarms that receive their power from your home's electrical system (hardwired alarms) usually have a back-up battery that will need to be replaced once or twice a year.info
Ideal Location info
Ideal Location <p><strong><font size="2">Different rooms in a home can often have different dangers associated with them.</font></strong></p> <p>Many smoke alarms have features to specifically address different location-specific needs. Examples include:</p> <p>Hallways - A super-bright LED for the hallway to aid in lighting an escape path</p> <p>Bedrooms - An additional voice warning in the bedroom to help wake those who may sleep through the traditional beep</p> <p>Kitchens - A unique sensor algorithm detects real fires faster and reduces cooking-related nuisance alarms</p>info

10-Year Battery Powered - Smoke Alarms
10-year sealed battery smoke alarms (sometimes called smoke detectors) offer a variety of benefits to the millions of Americans who rely on continuous battery-powered smoke and fire detection in their homes. The alarms are powered by sealed, long-life lithium batteries for 10 years (the life of the alarm), meaning they are always on. The National Fire Protection Association recommends replacing smoke alarms every 10 years.
