PHOTOELECTRIC SMOKE ALARMS VS IONIZATION SMOKE ALARMS


Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”).
How they work: Photoelectric-type alarms aim a light source into a sensing chamber at an angle away from the sensor. Smoke enters the chamber, reflecting light onto the light sensor; triggering the alarm.

Ionization smoke alarms are generally more responsive to flaming fires.
How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.

Experts in the fire safety field have different opinions on what type of smoke alarms or smoke detectors are best suited for protection. For the best protection for you and your family, installing both photoelectric and ionization smoke alarms is recommended, as both flaming and smoldering fires are causes of fires in the home. Of course protection is always better than no protection, so make sure your home has a smoke alarm.
