Dual sensor smoke alarms blend both ionization and photoelectric sensors to offer the most complete fire detection. They can detect both quick, flaming flames and slow, smoldering flames, and are less prone to false alarms than either ionization or photoelectric smoke alarms alone.

However, Dual sensor smoke alarms tend to be more expensive than photoelectric or ionization smoke alarms by themselves. Dual sensor smoke alarms should be utilized in areas where both quick flames, flaming fires as well as slow burning fires can be a possibility, such as living rooms and bedrooms.
