Photoelectric and ionization smoke detector

Both types of smoke alarms have their advantages as both flaming and smoldering fires can occur in your home. While an ionization alarm will. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.

Download this chart on ionization smoke alarms (PDF, 9KB). Photoelectric smoke alarms are generally more responsive to fires that begin with a long period of smoldering (called “smoldering fires”). As we mentioned earlier, each of these devices work on a different principle and therefore are likely to respond to different conditions differently. Because both ionization and photoelectric smoke alarms are better at detecting distinctly different yet potentially fatal fires, and because homeowners cannot predict what type of fire might start in a home, the USFA recommends the installation of both ionization and photoelectric or dual sensor alarms.

The First Alert Hardwire Dual Photoelectric and Ionization Sensor Smoke Alarm with Battery Backup is designed to provide peace of mind. The photoelectric and ionization sensors on this fire detector alert you to both smoldering and fast-flaming fires, offering comprehensive detection and early warning. There are smoke detectors that have the two technologies integrated into one smoke alarm detector.

We recommend the following for customers who may want to buy both photoelectric smoke detector and ionization smoke detector. You get double protection in. By Skip Walker, ACI, MCI. Imagine your car air bags deploying randomly when you hit a pothole, but failing over half the time in a collision. These alarms use “ions,” or electrically charged particles, to help detect smoke in the air.

But, ionization detectors cannot detect large smoke particles as well. In many cases the black smoke you are describing consists of large particles and will NOT be detected by ionization detectors. What is photoelectric emission?

Sources of these fires may include cigarettes burning in couches or bedding. The dual smoke detector has both ionization and photoelectric technology inside. An ionization smoke alarm contains a small amount of radioactive material.

Photoelectric smoke detector technology is generally more sensitive than ionization smoke detector technology at sensing large smoke particles, which tend to be produced in greater amounts by smoldering fires, which may smolder for hours before bursting into flame. With this fire alarm , you no longer need to choose just one technology. Smoke Alarms : Smoke alarms will detect most fires more rapidly than heat detectors. This alarm features two latching features and two silence features. I’ve been hearing more and more about this push, but after recently listening to an impassioned speech on the benefits of photoelectric smoke alarms over ionization alarms , I started taking an informal inventory of the smoke alarms that are installed in Minnesota homes.

Jeff Rossen and Avni Patel. Kidde offers photoelectric smoke alarms , ionization smoke alarms , and dual sensor alarms , which combine both technologies in one unit. Regardless of the technology, the most important thing is to ensure that you have working smoke alarms on every floor of your home, inside each bedroom and outside sleeping areas.
