There are generally two types of smoke alarms - ionization smoke alarms and photoelectric smoke alarms. All fires produce smoke particles in varying number and size. Ionization smoke alarms are generally more sensitive than photoelectric smoke alarms at sensing small smoke particles.

The different isotopes diffuse into an ion source where they are ionized. A vertically aligned electrical field (AC and/or DC) can be applied over the electric field, and the photoelectric effect can be studied by observing how  ionization.

Photoelectric smoke alarms typically cost about twice as much as the ionization type. The other reason is that ionization smoke alarms will outperform photoelectric alarms in the event of a fast moving fire. The faster reaction time can be measured in tens of seconds, but in the event of a fast moving fire, these are precious seconds.

These are items that produce flames right away and do not have as much smoke as a smoldering fire. 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).

they transition from the solution phase to the gas phase during soft ionization. of novel push-pull chromophores: photoelectric properties and application to 

Photoelectric vs ionization

You should see “Photoelectric” or ” Ionization”, or possibly even “P” or “I”. While an Ionization alarm will eventually detect a smoldering fire, it will do it at a much slower rate than a photoelectric alarm. Thus,its recommended to use a combination of both smoke alarms. to receive the fastest warning. Photoelectric smoke alarms are generally better than ionization smoke alarms at detecting smoldering fires.

PhoToeLecTric Vs. ionizaTion TechnoLoGies Ionization smoke detectors: • Use radiation to detect smoke. • More effective in detecting flaming fires. • Increased risk of nuisance alarms caused by steam or cooking smoke.

Sources of small smoke particles: Hot, flaming fires that consume combustible materials rapidly and may spread quickly, such as: What is the difference between Photoelectric and Ionization smoke alarms? Ionization Smoke Alarms - Generally are more effective at detecting flaming fires, which consume combustibles quickly and spread rapidly.

Photoelectric vs ionization

For this reason, photoelectric devices (mentioned above) will provide family members with less advance warning to get to safety before hot, flame-intense fires engulf the residence. Ionization devices more quickly detect low-smoke fires, setting off the alarm sooner. Doubly Safeguard Your Home with Photoelectric and Ionization Technologies There are generally two types of smoke alarms - ionization smoke alarms and photoelectric smoke alarms.

Main outcome measures were: percentage of study alarms that were working, observed reasons for non-functional status, and self-reported frequency of nuisance alarms at 9 and 15 months of follow-up.
