What is an Ionization Smoke Alarm?
There are two main types of home smoke alarms; ionization smoke alarms and photoelectric smoke alarms. Knowing the difference between these is essential to choosing the right smoke and fire detector for your home and family. According to the National Fire Protection Association (NFPA), roughly 96% of households in the United States have at least one smoke alarm in their home, yet it’s unlikely people truly understand the difference between the two major types of alarms. . Learn more about the difference between each type and the benefits of installing an ionization alarm in your home.
What Type of Fires Does an Ionization Alarm Detect?
Generally, ionization detectors are more responsive to flaming fires. The term “flaming” fires refers to fires resulting from flammable liquids, wood or paper. This type of fire produces a lot of flames with a limited amount of smoke. Most house fires are categorized as fast-flaming fires, which is why ionization alarms are popular in homes. To be safe, we recommend having both types of home fire detectors installed or installing dual sensor smoke alarms that detect multiple types of fires.
How do Ionization Alarms Work?
Ionization chambers are the essential difference between ionization alarms and photoelectric alarms. Within the ionization chamber, there are two plates with voltage in between them. If an electron in this space is knocked out of place due to smoke entering the chamber, it causes ionization, and, in response, the fire alarm goes off.
