Two Sensor Smoke Alarms

Smoke alarms with dual sensors incorporate photoelectric and ionization sensors to provide the most complete fire detection. They are effective in detecting both fast, flaming fires and slow burning fires and are less vulnerable to false alarms than either ionization or photoelectric smoke alarms by themselves.

However, dual sensor smoke alarms are typically more expensive than either photoelectric or ionization smoke alarms alone. Dual sensor smoke alarms are best employed when both rapid burning fires, flames and slow, smoldering fires are possible like bedrooms and living rooms.
