Ionization Smoke Alarm

Definition: An ionization smoke alarm is a type of smoke alarm that’s designed to detect fast-flaming fires by sensing very small smoke particles.

Parent Tip: Ionization alarms can respond quickly to open-flame fires, but they may be slower to detect slow, smoky fires. Many families choose a dual-sensor alarm (ionization + photoelectric) for broader protection.

Why It Matters: Understanding the difference between alarm types helps you choose the best protection for your family—especially at night when everyone is asleep.
