They are also more vulnerable to false alarms caused by cooking or steam and can cause a lot of frustration for homeowners. Ionization smoke alarms should be used in areas with no cooking appliances, for example, hallways and bedrooms.

Dual Sensor Smoke Alarms

Smoke alarms with dual sensors blend both ionization and photoelectric sensors to provide the most comprehensive fire detection. They are good at detecting both rapid, flaming fires as well as slow burning fires and are less susceptible to false alarms than either ionization or photoelectric smoke alarms alone.

However, smoke detectors with dual sensors tend to be more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensors are best utilized in areas where both quick, flaming fires and slow, smoldering fires are possible like bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms connect to your home’s Wi-Fi network and send out alerts to your phone or other devices if they spot smoke or fire. They are also able to be connected to other intelligent home devices such as smart thermostats as well as security devices.
