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. Avoid installing them in kitchens or rooms that have steams like saunas and bathrooms to prevent false alarms. Do not install smoke and carbon dioxide detector in breezy and ventilated areas like in front of electric fans, air conditioners, windows and doors.
