Smoke Alarms for Ionization

Smoke alarms that use Ionization utilize some radioactive substance to ionize air within the alarm. If smoke gets into the alarm, it disrupts the process of ionization and causes an alarm sound to be heard. These kinds of smoke alarms are effective in detecting rapid burning fires and generally cost less in comparison to photoelectric fire alarms.

However, ionization smoke alarms aren’t as effective at deterring slow burning fires. They are also more prone to false alarms from cooking or steam and can cause a lot of frustration for homeowners.

Dual Sensor Smoke Alarms

Dual sensor smoke alarms combine both ionization and photoelectric sensors to provide the most complete fire detection. They are effective in detecting both fast, flaming fires and slow burning fires and are less susceptible to false alarms than either ionization or photoelectric smoke alarms on their own.

However Dual sensor smoke alarms are typically more expensive than photoelectric or ionization smoke alarms on their own. Dual sensor smoke alarms should be used when both quick, flaming fires and slow, smoldering fires are feasible for example, bedrooms and living spaces.

Smart Smoke Alarms

Smart smoke alarms are linked to your home’s Wi-Fi networks and send out notifications to your smartphone or other devices if they detect smoke or fire. They also can be integrated into other home smart appliances, such as smart thermostats or security systems.
