Two Sensor Smoke Alarms

They can detect both rapid, flaming fires as well as slow burning fires and are less prone to false alarms than either photoelectric or ionization smoke alarms on their own.

However, smoke detectors with dual sensors are typically more expensive than photoelectric or ionization smoke alarms alone. Dual sensor smoke alarms are best used when both fast, flaming fires and slow, smoldering fires are possible for example, living rooms and bedrooms.

Smart Smoke Alarms
