Dual Sensor Smoke Alarms

Dual-sensor smoke alarms incorporate photoelectric and ionization sensors to offer the most comprehensive fire detection. They can detect both rapid, flaming fires as well as slow, smoldering flames, and are less prone to false alarms than either photoelectric or ionization smoke alarms by themselves.

However, smoke detectors with dual sensors are generally more expensive than either photoelectric or ionization smoke alarms by themselves. Dual sensors are best employed in areas where both rapid, flaming fires and slow burning fires can be a possibility like bedrooms and living spaces.

Smart Smoke Alarms

Smart smoke alarms are linked to the Wi-Fi network in your home and send out alerts to your phone or other device if they detect fire or smoke. They also can be integrated into other home smart devices, like smart thermostats, or security systems.
