Question is, at what percentage does the smoke thickness or volume need to be to set off both Photoelectric and Ionization Alarms, need a percentage for a research study
Thanks for your video.We focus on Smart Sensor Alarms, hoping to provide safety protection for more people, smoke alarms, carbon monoxide alarms, Door Sensor,motion sensor，etc.A small item may be able to help many families stay away from disasters.
I found this video because I triggered my smoke alarm by having a bath in a closed bathroom and the sudden rush of air probably was what triggered it 😅 Very short and nice video! Thank you!
Hi Kathryn, thank you for watching. It may or may not. It depends on proximity of the incense stick to the smoke detector, the size of the enclosed space , how much ventilation there is, and whether the smoke from the incense stick is flowing toward or away from the smoke detector. You won't know until you test it out and if needed you can press the test button to hush the alarm if you need to ventilate the smoke from the insense stick.
Thanks for watching. These video simplifies the operation of the smoke detector. The exact wiring is more complicated than this so without wiring diagrams and more info, this is a hard question to answer in more detail.
Ionizing detectors use an americium alpha particle source to ionize the air path between two metal surfaces. This lowers the electrical resistance of the air path. Smoke particles block many of the alpha particles increasing the resistance of the air path. When the resistance increases sufficiently an electronic circuit detects that and sounds the alarm.
Thank you for sharing that detailed breakdown, we kept it simple for the video but do realize there are those who are interested in how it works at a more intricate level.
I think we had the second one growing up cuz I think would go off easily I remember one of us kids would have to use a towel and wave it at the smoke detector 😂
Sensitive smoke detectors and weak bathroom fans were the perfect storm in our home as the steam from the shower would consistently trigger the detector in the adjacent hallway.
Hi Will, Thank you for watching. Since smoke rises its best to have the smoke detector high up on the wall or on the ceiling. Avoid any "dead air" spaces like in corners. If you mount an alarm on the ceiling make sure it is in the middle in a location that the air will circulate over top of. Also its not recommended to place a smoke detector near any vents that might remove the smoke and interfere with the detection. The National Fire Protection Association (NFPA) recommends placement of at least one smoke alarm on every level of the home and one alarm in every bedroom. Carbon monoxide, however, mixes with the air, which is why CO detectors should be mounted in or near bedrooms and living areas, on a wall place six inches below the ceiling to six inches above the floor. This is a good resource if you'd like to read more www.kidde.com/home-safety/en/us/support/help-center/browse-articles/articles/what_is_the_best_placement_for_alarms_.aspx Hope this helps!
I just had a false alarm - when I removed the device from the ceiling, a small fly flew out of the detector. I guess this is something that can happen apparently, an insect gets into the detector and disrupts the beam.
This video was a quick view into smoke detectors but you are right, that most ionization detectors use a very small amount of the isotope americium-241. The radiation emitted is a very insignificant amount, and has low penetrating power which is blocked from the plastic housing of the smoke detector.
Thanks for watching. Ionization detectors will commonly have a small americium source encased in a layer of foil and ceramic which prevents the alpha particles from traveling outside of the smoke detector. These will still use a standard 9V battery as well.
Hello hope everything is good, by the grace of GOD I thought of an analogy that relates to this vid and the video here goes well with it. Do I have permission to use the short video footage ?
Thanks for watching Kayode. It depends on how you intend to use the footage. Playing the video on youtube for other people in a classroom or teaching setting is perfectly fine. Using this video as part of another video or creation is not permitted without permission, and we'd have to have more information first before giving permission.

Thanks for watching. The standard way of specifying smoke detector sensitivity is a measurement of Obscuration. Obscuration is the effect that smoke has on reducing light intensity, expressed in percent absorption per unit length. Higher concentrations of smoke result in higher obscuration levels. Ionization 2.6-5.0% obs/m (0.8-1.5% obs/ft) Photoelectric 0.70-13.0% obs/m (0.2-4.0% obs/ft) This means that a ionization smoke detector will be triggered when 1 meter of smoke blocks roughly 2% to 5% of the light that passes through that area. Overall this number is not something that consumers need to know when buying or using smoke detectors.
AMRE SupplyHi Bukit. Please read ‘The Combo Con’ document which explains why so much legislation around the world now specifically excludes combination ionization/photoelectric alarms. Thank you. www.thewfsf.org/combocon_files/TheComboConV2.1b.pdf

My SMOKE DETECTORS are driving my whole family crazy. They go off if someone is using talcum powder or deodorant, goes off if I'm vaping or if the automatic air freshener goes off. They are hotwired throughout the house so can't be disarmed by taking the battery out. I know that they are a great thing to have but no-one can relax, especially when they SCREAM at 2am when the cats or dog trigger the automatic air fresheners. Any advice would be gratefully received.
Thanks for watching. You could try a different type of smoke detector that might be not as sensitive to talcom powder or deodorant. You could buy one smoke detector, turn it on and do some tests, if it is better, then you could replace the rest of the smoke detectors with the same model.
Thanks for watching! You're not the first person to watch this video after a smoke alarm. Just like how most of our viewers only watch "How a Furnace Works?" after something doesn't work in their furnace: ruclips.net/video/tVLtJwix-_8/видео.html
Thanks for watching. If you're not sure if its working then it would be best to test your smoke detector. There is a test button on most models. If it doesn't beep then you'll have to replace the batteries or get a new one.
Find out more at: www.SmokeAlarmWarning.org Australian legislation (Queensland and the Northern Territory) and legislation in Zealand and some U.S. States mandates the use of photoelectric smoke alarms. Many authorities advise photoelectric alarms are "better" but for legal and political reasons are not allowed to warn that there is anything wrong with ionization alarms. However, in 2016 Australia's most senior fire official representing all fire brigades across Australia and New Zealand went public warning that "ionization smoke alarms should be banned". See his warning on Australian TV and discover for yourself why ionization smoke alarms should be banned: www.SmokeAlarmWarning.org
Hi Adrian, thank you for the information. In Canada both the provincial and federal recommendations have mentioned photoelectric and ionization alarms as viable options to protect. There isn't too much discussion on the precise efficacy of the alarms in specific conditions. With that in mind there are still dual alarms available as these provide the most complete protection.

Right now, there is no smoke or bad batteries. The fire Department men came by and checked says it is a short in the system. How one can explain?
