Dual sensor smoke alarms blend both ionization and photoelectric sensors to offer the most complete fire detection. They are effective in detecting both quick, flaming flames and slow burning fires and are less prone to false alarms than ionization or photoelectric smoke alarms by themselves.

However dual sensor smoke alarms are generally more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensor smoke alarms are best utilized when both fast flames, flaming fires as well as slow burning fires can be a possibility, such as bedrooms and living rooms.
