Smoke alarms of this type are excellent at detecting quick, flaming fires and are generally less expensive than photoelectric smoke alarms.

Photoelectric smoke alarms use an illuminating beam for detecting smoke. If smoke gets into the alarm, it scatters light, which causes an alarm sound. Smoke alarms of this type are good at detecting slow, smoldering fires and are less prone to false alarms from cooking or steam.

Smoke alarms with dual sensors blend 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 ionization or photoelectric smoke alarms on their own.

Dual sensor smoke alarms should be utilized for areas in which both quick flames, flaming fires as well as slow, smoldering fires are possible for example, living rooms and bedrooms.
