Two Sensor Smoke Alarms

Smoke alarms with dual sensors combine photoelectric and ionization sensors to provide the most comprehensive fire detection. They can detect both rapid, flaming fires as well as slow burning fires and are less vulnerable to false alarms than either photoelectric or ionization smoke alarms by themselves.
