Dual-sensor smoke alarms blend photoelectric and ionization sensors to offer the most complete fire detection. They can detect both fast, flaming fires and slow, smoldering flames, and are less vulnerable to false alarms than either ionization or photoelectric smoke alarms alone.

However, Dual sensor smoke alarms are generally more expensive than either photoelectric or ionization smoke alarms by themselves. Dual sensor smoke alarms should be employed in areas where both rapid, flaming fires and slow burning fires are possible like bedrooms and living spaces.

Smart smoke alarms connect to your home’s Wi-Fi network and send out notifications to your smartphone or other devices if they detect smoke or fire. They can also be integrated with other smart home appliances, such as smart thermostats or security systems.
