Hi! I think the article should describe in more detail, what the effects of a smoke detector are. Because: It looks like there were never so many final falls and terminal smoke intoxications as now (after they all have a smoke detector in their bedroom in F.Rep.Germany...)... Does anybody know some scientific studies? Thx. Bye. -- 2020-08-27T07:32:23UTC //forgot to sign... Homer Landskirty (talk) 14:40, 29 December 2022 (UTC)[reply]

Erwin Sick

Apparently Erwin Sick is given credit for the first smoke detector, but not much has been written about it. Any more detailed information? "In 1956, Sick is granted the second patent for a new type of photoelectric retro-reflective sensor, followed in 1958 by the patent for the first smoke detection device in the world." ^[1] Rhynchosaur (talk) 16:59, 5 August 2022 (UTC)[reply]

TL:DR not relevant to the article-

This seems to be the original patent it is more of a security sensor (Photoelectric sensors | Reflex Array | SICK) used in industry production than a fire alarm product. Here is about there history on their own site: SICK's company history | SICK Fackbok.se (talk) 20:25, 11 April 2023 (UTC)[reply]

Added discussion of radiation

Added sections on radiation in and disposal of ionization smoke detectors, which are generally being replaced by photo-electric smoke detectors.

Officials at the US Department of Energy provided references to documents published by the US Nuclear Regulatory Commission that report on studies of Ionization smoke detectors done in about 1978 and 2001. They also provided links to a backgrounder by the NRC and another backgrounder by the US Environmental Protection Agency (EPA). Bruce Esrig (talk) 09:48, 24 September 2022 (UTC)[reply]

Wiki Education assignment: Industrial Hygiene and Ergonomics- Graduate Student Projects

SMOKE DETECTORS VS SMOKE ALARMS

A smoke detector by definition only senses or detects. It has no audible or visual output. Detectors are used in fire alarm systems that have a control panel which the detector sends a signal to when it detects smoke, a heat rise or other material it is designed to sense. It is useless in almost all home applications. Smoke alarms are designed to both sense AND give off an audible and/or visual output such as a high db alarm, a strobe light or voice. Smoke alarms are what are used in single family homes or residences that are not required to have a fire alarm system. Umpyprof (talk) 20:12, 21 February 2024 (UTC)[reply]

The name "Smoke Detector" is commonly used to describe a combined detector+alarm and in normal use means the same as "Smoke Alarm". I am sure that pure detectors without any alarm function exist but this does not mean that the item known as as Smoke Detector "has no audible or visual output". Mtpaley (talk) 00:53, 22 February 2024 (UTC)[reply]

You might have a point though on the order of redirect. Currently "Smoke Alarm" redirects to "Smoke Detector" and this article is clearly written with a domestic smoke alarm in mind. It might make more sense to reverse this and make smoke detector redirect to smoke alarm which is renamed from the current smoke detector page. Mtpaley (talk) 01:03, 22 February 2024 (UTC)[reply]

If you have ever taken or taught a fire alarm system course as I have, one of the first things you learn is that a smoke detector is not the same as a smoke alarm and using the terms interchangably may be a serious mistake, especially to those who are not familiar with the subject. In fact the subject comparing detectors to alarms is on provincial licencing exams for those who wish to work on fire alarm systems. If you are going to use technical terminology, use it correctly. If you want to continue to use the 2 terms synonymously go right ahead and hope you never give someone the wrong information. I'm not going to reply again. Any person who reads my post will certainly get my point. Umpyprof (talk) 02:36, 22 February 2024 (UTC)[reply]

Very few, if any, persons that are licensed to work on fire alarm systems are also inclined to edit Wikipedia. Your expertise in the area would be greatly appreciated as there is a deficiency in a lot of the fire safety material on this site, as evidenced by the inaccurate terminology used here in favor of the "more common" name.

-== Typical smoke detector obscuration ratings ==
+Hi!
-This table doesn't quite make sense. Ionization and Photoelectric are two categories of sensors used to detect smoke, while beam, aspiration, and laser are products that utilize these technologies in their product. Also, percent per foot is not how sensitivity is commonly measured in beam-type smoke detectors, which is probably why there is no citation for the value entered. I am going to reformat this table and obtain citations for all values unless there is reasonable argument against.  <small><span class="autosigned">—&nbsp;Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[User:EEthug|EEthug]] ([[User talk:EEthug|talk]] • [[Special:Contributions/EEthug|contribs]]) 18:38, 1 May 2014 (UTC)</span></small>

+Added sections on radiation in and disposal of ionization smoke detectors, which are generally being replaced by photo-electric smoke detectors.
-Ionization and photoelectric detectors each have their own merits, so why is the [[Smoke detector#Performance differences|Performance differences]] section so anti-ionization?! Even the comparison table in that section shows that ionization detectors are more sensitive to lower obscuration values, on average (yeah, okay, so there's one photoelectric model than can supposedly 0.2%/foot, but that's clearly an outlier if you follow the reference). Furthermore, photoelectric detectors obviously stand no chance of ever detecting invisible smoke particles, which obviously won't obscure anything. If ionization detectors are so "deadly", why are they still on the market and legal in most places? Why are there combination detectors that offer both ionization and photoelectric technologies if photoelectric can do everything that ionization can do—just better? I don't buy it. We should probably find the other side of the argument and [[WP:NPOV|represent it]] here. –&nbsp;<kbd>[[User:voidxor|<span style="color: #00F">void</span>]][[User talk:voidxor|<span style="color: #000">xor</span>]]</kbd> 21:16, 30 July 2015 (UTC)

-: i think that section is POV on another level, too: what performance? in F.Rep.Germ. i cannot see any 40% drop in smoke/fire/flame deaths (ICD-10 X0...), although the legislative ordered a lot of those photoelectric devices... furthermore smoke/fire/flame per (official) inhabitant seems to be more often in the US than in F.Rep.Germ., although F.Rep.Germ. does not have smoke detectors for decades... a newspaper said, that there is no proof for the usefulness of a smoke detector... but of course i do as the gov orders and check the functionality weekly by pressing the test-functionality-button (my computer has an alarm for that)... :) --[[User:Homer Landskirty|Homer Landskirty]] ([[User talk:Homer Landskirty|talk]]) 07:13, 31 July 2015 (UTC)

+== SMOKE DETECTORS VS SMOKE ALARMS ==
-:::: The question is asked above, "If ionization detectors are so "deadly", why are they still on the market and legal in most places?" The answer is because the manufacturers fight to keep the truth about them from the public evidenced by the Confidentiality Order placed on campaigners after ionization smoke alarm manufacturer Kidde (owned by UTC) failed to disclose the level of smoke their ionization alarm activated at under controlled scientific tests conducted by the Australian government scientific organization, the CSIRO. This was despite repeated requests by an Australian member of parliament:

-::::* Request for disclosure of smoke obscuration by Australian member of parliament: www.SmokeAlarmWarning.org/csiro.html
