9120b Smoke Detector
A 9120b smoke detector is a device that is used to detect the presence of smoke in a given area. These detectors are often used in commercial and industrial settings, as well as in residential homes. Smoke detectors work by using a small amount of radioactive material to ionize the air in their sensing chamber. When smoke particles enter the chamber, they disrupt the ionization process, which triggers the alarm. 9120b smoke detectors are powered by either batteries or a 120-volt AC power source.
