Ionization smoke alarms should be utilized in areas with kitchen appliances that are not in use, for example, bedrooms and hallways.

Photoelectric Smoke Alarms

Two Sensor Smoke Alarms

Dual sensor smoke alarms incorporate photoelectric and ionization sensors to offer the most complete fire detection. They are good at detecting both rapid, flaming fires as well as slow, smoldering fires, and are less susceptible to false alarms than either photoelectric or ionization smoke alarms alone.

However smoke detectors with dual sensors are generally more expensive than either photoelectric or ionization smoke alarms on their own. Dual sensor smoke alarms should be employed when both quick burning fires, flames and slow, smoldering fires are feasible, such as living rooms and bedrooms.

Smart Smoke Alarms

Smart smoke alarms are linked to the Wi-Fi network in your home and can send notifications to your smartphone or any other device when they spot smoke or fire. They are also able to be connected to other intelligent home devices, such as smart thermostats and security alarms.
