WebApr 10, 2012 · The main reason is cost. Photoelectric smoke alarms typically cost about twice as much as the ionization type. The other reason is that ionization smoke alarms will outperform photoelectric alarms ... WebIonization smoke detectors work by using a small amount of radioactive material to ionize the air in the sensing chamber. This creates a small current that flows between two electrodes. When smoke enters the chamber, it disrupts the current, triggering the alarm. Photoelectric smoke detectors work by shining a light source into the sensing chamber.

Thanks to ... WebScore: 4.9/5 (38 votes) . 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. WebApr 10, 2012 · Almost 40 years ago, The Gillette Company laucned a product line called Captain Kelly which featured Photo Electric Smoke Detectors. They had a RV that was used to present the the Photo Electric system vs Ionization and took people through an actual demonstration of how much smoke (4%) was necessary to trigger the Ionization alarm. electric bikes langford
