Dual Smoke Alarms with Smoke Sensors

Dual-sensor smoke alarms combine both ionization and photoelectric sensors to offer the most complete fire detection. They are effective in detecting both rapid, flaming fires as well as slow, smoldering flames, and are less vulnerable to false alarms than either photoelectric or ionization smoke alarms by themselves.

However Dual sensor smoke alarms are typically more expensive than either photoelectric or ionization smoke alarms by themselves. Dual sensor smoke alarms are best employed in areas where both rapid burning fires, flames and slow burning fires are possible like bedrooms and living rooms.
