This is NOT a photoelectric, or dual sensor alarm. It uses old school ionization.
From Consumer Reports: ;Ionization smoke detectors are best at detecting the small particles typical of fast, flaming fires. But in our tests, all tested p.oor.ly for detecting smoky, smoldering fires. Ionization units are prone to false alarms from burnt food and steam, so don’t mount them near a kitchen or bathroom.
