What Is A Photoelectric Smoke Detector?
The different technologies in smoke detectors have very important implications. The science behind smoke detectors is meant to alert you as quickly as possible in dangerous situations. For example, photoelectric smoke detectors are well-known for protecting against smoldering fires. Whether it be a smoldering fire or a flaming fire, you’ll want to be aware as soon as possible. At First Alert, we want to make sure you understand the technology that helps keep you safe, so you can make the best decision when it comes to protecting your home and family.
How Do Photoelectric Smoke Detectors Work?
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. The alarm detects smoke; when smoke enters the chamber, it deflects the LED light from the straight path into a photosensor in a different compartment in the same chamber. As soon as light beams hit this sensor, the alarm begins to sound.
How Do Photoelectric Smoke Detectors Compare To Other Smoke Detectors?
Other popular technologies for smoke detectors are ionization alarms and dual sensor smoke detectors. The dual sensor smoke detector has both ionization and photoelectric technology inside. Ionization smoke alarms are best for detecting rapid flame fires, while photoelectric smoke alarms protect against slower, smoldering fires.
Should I Have A Photoelectric Smoke Detector?
It’s safe to say every home should have a photoelectric smoke detector. While the ionization smoke detector has been proven more effective in detecting flaming fires, photoelectric alarms outperform it when it is a smoldering fire. For best protection, it is recommended to have both types of fire alarms throughout your home.
