Question: I’ve heard of two different kinds of smoke detectors. What are they and which one is better?
Great question! We’ve all read and heard of stories regarding devastating house fires in the Omaha, Lincoln, Council Bluffs and surrounding areas. Sometimes it’s the smallest things we overlook that can make a BIG difference when it comes to minimizing and maybe even preventing damage to your biggest investment. Smoke detectors are our topic this week! Let’s answer this and more from our AmeriSpec inspectors.
Answer: There are two different types of smoke detectors:
1. Photoelectric Detector
Contains a light and a light sensor. When smoke enters the detector, the sensor senses that the light beam has been
disrupted and sets off an alarm.
2. Ionization Detector
Contains an ionization chamber where particles are charged using a small amount of radioactive material. When smoke
enters the chamber, the detector senses the change in the current and sets off the alarm.
Both types of detectors will detect all types of fires; however, the photoelectric detectors appear to sense smoldering
fires better, while the ionization detectors seem to sense flaming fires better. Since one cannot predict which type of fire
will occur, fire departments are recommending that smoke detectors with both types of sensors (either in one unit or two separate units) be installed.
A dual Unit has both photoeclectric and ionization detectors in one device. Click the link for a few more tips on fire safety: Fire_Safety from AmeriSpec
