Ionization smoke detector

The two most commonly recognized smoke detection technologies are ionization smoke detection and photoelectric smoke detection. Ionization smoke alarms are generally more responsive to flaming fires. How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and. This type of smoke detector is more common because it is inexpensive and better at detecting the smaller amounts of smoke produced by flaming fires.

Inside an ionization detector is a small amount. Because of this shielding, the smoke detector poses no radiation health risk when they are properly handled. Within the ionization chamber , there are two plates with voltage in between them. If an electron in this space is knocked out of place due to smoke entering the chamber, it causes ionization , an in response, the alarm goes off.

The first smoke detector type, ionization alarms are generally more responsive to a flaming fire (for instance, when a lit candle tips over and ignites a curtain), according to the National Fire Protection Association (NFPA). These alarms use “ions,” or electrically charged particles, to help detect smoke in the air. This radioactive material ionizes the air in the sensing chamber, and makes it conductive, thus facilitating current flow between the two charged electrodes present within.

While an ionization alarm will eventually detect a smoldering fire,. If you have ionization smoke alarms in your home, install. 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. How does an ionization smoke detector work? What are some radioactive elements used in smoke detectors? Which smoke detector is best? Free 2-day Shipping On Millions of Items.

The smoke detector senses the drop in current between the plates and sets off the horn. Check the back of your smoke detector for a sticker bearing the radiation symbol to determine which type of detector it is. On the other han ionization smoke detector is more responsive to flaming fires. The photoelectric smoke detector is considered more environmentally friendly.

This is because, ionization detectors use radioactive elements such as americium-241. When choosing what smoke detector to install in your home,. 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. This smoke detector is easy to install since there are no wires neede and it includes a smart hush feature to silence false alerts.

The Kidde Smoke Detector uses ionization sensors to detect invisible fire particles, but it does not include a photoelectric sensor. Experts recommend that for optimal protection you have both types of sensing technology in your home. Save Up to - Authorized Distributor - Expert Advice - Free Shipping!
