Dual Smoke Alarms with Smoke Sensors

Smoke alarms with dual sensors combine photoelectric and ionization sensors to offer the most comprehensive fire detection. They are good at detecting both rapid, flaming fires as well as slow, smoldering flames, and are less susceptible to false alarms than photoelectric or ionization smoke alarms on their own.

However Dual sensor smoke alarms are generally more expensive than either photoelectric or ionization smoke alarms alone. Dual sensor smoke alarms should be utilized in areas where both fast, flaming fires and slow, smoldering fires are possible, such as bedrooms and living rooms.
