What Does A Photoelectric Smoke Alarm Detect? A photoelectric smoke detector is characterized by its use of light to detect fire. Inside the alarm, there’s a light-sensing chamber. In this chamber, an LED light shoots a beam of light in a straight light across the chamber. Which is better ionization or photoelectric smoke alarm? Ionization
Why Would The Alpha Particles In The Smoke Detectors Remove Electrons From Air Molecules? A radioactive source “decays,” or sheds particles and photons from unstable atoms. The particles interact with neutral air molecules flowing through the chamber. The particles remove electrons from air molecules, creating positive ions. Why do smoke detectors emit alpha particles? Ionization
What Is Code For Fire Alarms?

On levels without bedrooms, install alarms in the living room (or den or family room) or near the stairway to the upper level,
Why Should Smoke Alarms Have A Long Half-life? The source should have a long half-life so that the smoke detector does not have to be replaced too frequently, and so that the count rate remains almost constant each day. Radioactive isotopes may not go where they are wanted. Use of isotopes with a short half-life
