FAQ:

What powers a smoke alarm?

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 lithium ("long-life") battery. Alarms that get power from your home's electrical system, or "hardwired," usually have a back-up battery that will need to be replaced once a year.

Are smoke alarms expensive?

Smoke alarms are not expensive and are worth the lives they can help save.
