First Alert Dual Sensor Smoke Alarms implement photoelectric and ionization sensors. Dual sensor smoke alarms excel at detecting the presence of both smoldering and fast-flaming fires, ensuring optimal levels in peace of mind. Both sensors work together to provide complete smoke and fire detection. The photoelectric sensor detects smoldering fires from objects like cigarettes burning on furniture or in trash cans. The ionization sensor excels in detecting fast-flaming fires like erupting kitchen grease fires or combustibles.
For maximum protection and full coverage from all types of fires, your best option is to use a dual sensor smoke detector that features both photoelectric and ionization sensing technologies.
Where to Place Dual Sensor Smoke Alarms: One in every bedroom, and at least one on every level of the home.
