Photoelectric detectors[edit]

Note: There has been some recent research that has proven that "Photo-Electric" smoke alarms do a much better job at detecting large fires, whereas the Ionization detectors could only detect a small fire (which could in turn, could burn rapidly out of control) after a minimum of ten minutes! The photo-electric alarms however detected the fires almost a fast as they detected a large fire. This issue is still under investigation and research but the word is spreading and a few government (Australian, I'm not sure about others) organizations have admitted that these new alarms do work a lot better. — Preceding unsigned comment added by 203.166.253.179 (talk) 09:06, 5 June 2006 (UTC)

Smoke Detector vs Smoke Alarm[edit]

The introduction paragraph makes a statement that may need a rewrite of the article and its structure;

A smoke detector or smoke alarm is an active fire protection device, subject to stringent bounding, that detects airborne smoke and issues an audible alarm, thereby alerting nearby people to the danger of fire.

What I mean by this is that there is a difference between a Smoke Alarm comprising a sensor and audible warning device and a Smoke Detector that forms part of a network of sensors connected to an alarm panel.

Perhaps the article could be written with a summary of the technology of smoke detection (ionisation vs optical) and then the application of these technologies, being in the form of smoke alarms and smoke detectors. — Preceding unsigned comment added by Rport (talkcontribs) 12:12, 22 August 2006 (UTC)

Alternatively (by someone else): A smoke alarm is a device comprising a smoke detector and audible device. etc. The smoke detector might be incorporated into a device which communicates with an alarm panel. — Preceding unsigned comment added by 77.102.254.104 (talk) 04:45, 13 July 2009(UTC)

Suggest merge[edit]

Americium smoke detector contains no information not available from reading the package it came in and is redundant with this article; any unique content should be merged to give it context. --Wtshymanski (talk) 16:25, 18 March 2012 (UTC)

Done in April. --Wtshymanski (talk) 14:00, 13 August 2012 (UTC)

Typical smoke detector obscuration ratings[edit]

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. — Preceding unsigned comment added by EEthug (talkcontribs) 18:38, 1 May 2014 (UTC)

Page is better now! — Preceding unsigned comment added by Qwertyuiopasdfghjklzxcvbnmkeys (talkcontribs) 02:32, 11 April 2015 (UTC)
Fixed I just removed the uncited part about the beam and cleaned up the table a little. Hope that helps. – voidxor 21:04, 30 July 2015 (UTC)
Fixed Also, I removed the uncited Air-sampling section, which was under the Design level-2 header right alongside Ionization and Photoelectric. You're right about air-sampling and beam just being specialized implementations of photoelectric. – voidxor 23:02, 31 July 2015 (UTC)

POV of Performance differences section[edit]

Ionization and photoelectric detectors each have their own merits, so why is the 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 represent it here. – voidxor 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)... :) --Homer Landskirty (talk) 07:13, 31 July 2015 (UTC)
Should we maybe create a Legislation section and split the Performance differences section in half? That would at least take the biased chronological litany of local laws being passed, and move it away from the objective discussion of obscuration and the like. – voidxor 22:27, 31 July 2015 (UTC)
sounds like pretty good idea... the local legislation told me, that their decision is based on "belief" and not on scientific studies... --Homer Landskirty (talk) 06:21, 1 August 2015 (UTC)
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:

With all due respect, I worry your conspiracy theory might increase this article's bias toward photoelectric detectors, rather than helping to ensure neutrality. I'll go ahead and split the section though, as Homer and I'd discussed. – voidxor 19:15, 4 August 2015 (UTC)
