Smoke detectors can run off of a 9-volt battery or 120-volt house current.In this article, we will examine the two most common types of smoke detectors used today: photoelectric detectors and ionization detectors. And, we'll also take a look inside an ionization detector. Let's start with photoelectric detectors.moke detectors can run off of a 9-volt battery or 120-volt house current.
