Smoke detectors use different methods to detect smoke and fire, but work in similar ways. Photoelectric smoke detectors use a light source that refracts when smoke enters its chamber. That refraction triggers the alarm and sets off the beeping. While ionization smoke detectors use a chemical reaction to trigger the alarm. Both are effective at their jobs, but the best kind of smoke detector has both methods!
In this video, we go into the details about how photoelectric and ionization smoke detectors work, what their strengths are, their price ranges, and where you can find new ones if you’re looking for a new smoke detector.
And check out our resources below where you can find more fire safety tips on SafeWise.com like how to avoid a house fire, what to do if one happens, how to make a fire escape plan, and where to buy smoke detectors.
