Heat Detectors vs. Smoke Detectors: What’s the Difference?

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. Webboth photoelectric and ionization type alarm. Neither type of detector was demonstrably better in reducing nuisance alarms.” There is no statistical data to ... where photoelectric alarms are typically installed, false alarms occur, many due to lint from linens (which may be changed daily in the case of a hotel) and cat hair . ... ray the mover naples
