What is Understanding Ionization Smoke Alarms about?
There are three main types of smoke alarms: ionization, photoelectric, and combination. Ionization alarms detect flaming fires faster using a small amount of radioactive material to ionize air and detect changes in conductivity from smoke. Photoelectric alarms detect smoldering fires faster using a light beam that triggers an alarm when smoke disperses the light. Both technologies are commonly used, with ionization responding quicker to flaming fires and photoelectric to smoldering fires.
