However, ionization smoke alarms are not as effective at deterring slow burning fires. They also are more susceptible to false alarms caused by cooking or steam and can cause a lot of frustration for homeowners. Smoke alarms that ionize are best utilized in areas where there are kitchen appliances that are not in use, for example, hallways and bedrooms.

But, photoelectric smoke alarms aren’t as effective at detecting quick flames. They’re also typically more expensive than ionization alarms. Photoelectric smoke alarms should be used in areas in which there are cooking appliances, like kitchens and living spaces.

Dual Smoke Alarms with Smoke Sensors

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

However dual sensor smoke alarms tend to be more expensive than either ionization or photoelectric smoke alarms on their own. Dual sensor smoke alarms should be employed in areas where both rapid, flaming fires and slow burning fires are possible, such as bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms are linked to your home’s Wi-Fi network and send out alerts to your phone or other device if they spot smoke or fire. They can also be integrated with other smart home devices, for example, smart thermostats as well as security devices.

The smart smoke alarms can be good at providing real-time alerts, even when you’re not at home. But, they’re generally higher priced than conventional smoke alarms, and require an internet connection that is reliable to work properly.
