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.
There are many special features that can help protect you and your home, or make your safety products easier to maintain and operate. Many of these features are not well known by their name, so to learn more about specific features of a model, select it and view its detail page.
