They are also more prone to false alarms caused by steam or cooking and can cause a lot of frustration for homeowners.

Two Sensor Smoke Alarms

Dual-sensor smoke alarms blend both ionization and photoelectric sensors to provide the most complete fire detection. They are effective in detecting both rapid, flaming fires as well as slow burning fires and are less susceptible to false alarms than ionization or photoelectric smoke alarms alone.

However Dual sensor smoke alarms are typically more expensive than either photoelectric or ionization smoke alarms by themselves. Dual sensors are best utilized for areas in which both quick flames, flaming fires as well as slow, smoldering fires can be a possibility like living rooms and bedrooms.

Smart Smoke Alarms

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