Most flaming, fast-moving fires are a result flammable liquids, wood, or paper catching fire. These are items that produce flames right away and do not have as much smoke as a smoldering fire. Ionization alarms sense smoke by the work of ions (electrically charged particles), whereas photoelectric alarms detect smoke with a beam of light, according to the National Fire Protection Photoelectric vs. Ionization smoke detectors When looking for the best smoke detector for your property, you'll probably come across a face-off between ionization and photoelectric smoke detectors. Both happen to have valuable features for property owners concerned about the danger of fire and smoke. Smoke alarms come in two kinds: ionization and photoelectric.
Depending on the source of the smoke, one type of alarm gives a faster warning compared to the other.

There are two smoke detection technologies that are recognized as effective within the fire safety community, and ionization is one of them. Ionization smoke detectors generally work better when a fire is flaming, rather than just smoldering. 2020-04-10 Consumers Union, the nonprofit publisher of Consumer Reports, recommends you install smoke alarms with two different types of sensors: Ionization sensors ($10 and up) are better at detecting fast, flaming fires.

The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics , and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. You should see “Photoelectric” or ” Ionization”, or possibly even “P” or “I”. While an Ionization alarm will eventually detect a smoldering fire, it will do it at a much slower rate than a photoelectric alarm.
