On the other hand the ionization type smoke detector is more sensitive to flames than to smoke. It sets off an alarm faster than a photoelectric or optical beam smoke detector once it detects fire. Therefore it is best used to detect smoke from fast flaming materials like paper and wood. It is also cheaper to manufacture. Compared to photoelectric smoke detectors, it consumes less
power so a small battery can power it for month and is independent of external wiring. Since ionization type smoke detectors can detect particles smaller than smoke particles, they are prone to false alarms. Ionic smoke detectors use a radioactive isotope americium 241, and rules on proper disposal vary in each region. Some European countries have banned ionic smoke detectors. Most photoelectric smoke detectors run on AC power circuits meaning the users have to install the wirings around the house. Such smoke detectors also have a backup battery aside from the 120 volt power it needs to function.
Smoke detectors should be placed where smoke isn’t supposed to be.
