Smoke alarms with Ionization use a small amount of radioactive material to ionize the air within the alarm. If smoke gets into the alarm, it interrupts the process of ionization and causes an alarm sound to be heard. Smoke alarms of this type are effective in detecting rapid, flaming fires and generally are less costly in comparison to photoelectric fire alarms.

But, ionization smoke alarms aren’t as effective in deterring slow burning fires. They are also more prone to false alarms from cooking or steam, which can be frustrating for homeowners. Ionization smoke alarms should be used in areas where there are none of the cooking equipment, for example, bedrooms and hallways.

Two Sensor Smoke Alarms

Smoke alarms with dual sensors incorporate both ionization and photoelectric sensors to provide the most comprehensive fire detection. They are good at detecting both quick, flaming flames and slow, smoldering flames, and are less susceptible to false alarms than photoelectric or ionization smoke alarms on their own.

However dual sensor smoke alarms are typically more expensive than photoelectric or ionization smoke alarms alone. Dual sensors are best utilized when both rapid burning fires, flames and slow burning fires are feasible, such as living rooms and bedrooms.

Smart Smoke Alarms

Smart smoke alarms connect to the Wi-Fi network in your home and will send out alerts to your smartphone or any other device when they detect smoke or fire. They can also be integrated with other smart home devices, for example, smart thermostats and security alarms.
