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. Thus,its recommended to use a combination of both smoke alarms.

The two most commonly recognized smoke detection technologies are ionization smoke detection and photoelectric smoke detection. Ionization smoke alarms are generally more responsive to flaming fires. For this reason, photoelectric devices (mentioned above) will provide family members with less advance warning to get to safety before hot, flame-intense fires engulf the residence. Ionization devices more quickly detect low-smoke fires, setting off the alarm sooner.

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. Photoelectric sensors ($15 and up) are better at detecting smoldering fires.

Photoelectric should be used in areas that have steam, and ionization should be used in living rooms, bedrooms, kitchens, near air vents, etc.
