Yale HSA 6200 siren/beep got very quiet

[chaindaisy]

" ......Thanks, I'm in the driest part of the Canary Islnds ,where it is 29C outside as I type, with low humidity. We have had about 1/4 inch of rain in the last 18 months. Believe, me, condensation is not a problem! Added to which, I used to be an avionics engineer, so I understand the effects of condensation....."

Hi,

Now the last thing I want is to appear rude or upset anyone. I am so pleased your siren problem is resolved and wish you well for the future. That said, rain has nothing whatsoever to do with condensation inside a siren housing, niether does humidity. The high daytime temperature has a lot to do with it. We were taught this in school and did not require a degree in Avionics to understand the concept, which I have carried with me throughout my forty years on the ground in security, that simple piece of knowledge has helped resolve no end of external warning device problelms. I shudder to think that there is a security engineer on this site who is not knowledgeable in this area since it is probably one of the first aspects taught to anyone engaging in security as a career. I wish you well with your Avionics expertise, your home in the Canaries and your DIY alarm system.

The reason I mention avionics is that condensation in avionic boxes is one of the main causes of failures in aircraft systems, to the extent that the Swedish air force reduced unserviceability massively by plugging a commercial dehum into their aircraft avionic bays during overnight parking. So, I am well aware of causes and effects of humidity. The reason I mention where I live is because you pointed out I live in Spain, but more accurately I live 800 miles south of there there, where we have a very moderate temperature and low humidity year round, and my alarm is on a Northern facing wall, so doesn't get heated by direct sun. Aside from that, I've inspected the inside of the unit, and there is no sign of corrosion or tracking. Finally, the Yale technical help desk agreed that the actual noise making device appeared to have come unglued. So, I'll take your pleasure at my work experience, my choice of where I live, and the fact that I am quite competent to install an alarm kit sold by Yale at face value. Good luck with being an alarm installer.

This has been an interesting, but not helpful, introduction to this site.

Well, there's nothing like a bit of gratitude. Two pages of posts, two regulars and one passing through trying to help in two pages of posts, and you don't think the site is very helpful. It would be a pleasure to have you visit the site on occasion, since there may be posts which require help with condensation problems which only a true professional can resolve. Good luck and all the very best for the future.

I'm not entirely sure what the problem is here, the fact you feel competent because you can install an "alarm system" designed for the DIYer or that you got miffed that a "lowly" alarm engineer suggested your avionics career wouldn't serve you very well in your efforts in resolving this issue.

Oh and I live 250miles north of London the humidity in 80% and it's always raining.

Didn't take long for you to trip up and show your true colours did it 'Alarm' man... Always there ready to have a dig at someone else.

Eh?

That said, rain has nothing whatsoever to do with condensation inside a siren housing, niether does humidity. The high daytime temperature has a lot to do with it.

If that is the case then please explain the source of the water vapour that condenses into water inside the siren housing.

Hiya Gents.

I install, or at least I am responsible for the installation of, trade equipment. Does that suggest that I have a grudge against a diy system. Well, I get calls from DIY'ers every so often, and it makes no difference to me what equipment they've used. I'm the first to confess that I am not top of the class as far as say Micromark or Yale systems are concerned because I have to spend my time on other things. If Yale was such a bad system, why is it selling to a few thousand people every week. Yale must be doing something right so I've got nothing against their diy systems. Although it may appear that I was 'having a bash' at Yale in one of my posts, I can assure you that is not the case. In fact, I shall be posting a few questions in the knowledge that you can enlighten me on some of the finer aspects of Yale equipment.

What I do object to are idiosincratic posts which contradict both the writer and attempt to contradict the advice given by engineers on this site. I don't visit that regularly, just passing through so to speak, and the advice given by the regular engineers is first class in my opinion, so why should people who submit a query then attempt to belittle the very experts whom they have asked for help, I can't answer that one since I have, and always shall, treat every engineer on this site with respect, whether they choose to do the same with myself is entirely their decision.

It's obvious to me that you are a bit of a close knit family, insofar that you can take each other's jibes with a pinch of salt, and I admire you for this. Rather like my own engineers who wouldn't think twice about giving a colleague a 'ripping' during a tea break, which is soon forgotten when they are out in all weather working beside each other.

On this occasion, I have taken the time to read into this 'cry for help' and found a large degree of inconsistency. It would not be correct for me to go into detail, it is an unfair imposition on the initial writer. I have wished him well for the future, suggested a few probabilities regarding the fault and that is where it ends.

Bernard, I have read a few of your posts and it would appear that you are well versed in the electronics field, for which I congratulate you. It would be no insult to yourself to suggest that each of your colleagues on this site are equally well versed in electronics ... but they are security engineers who need to look at a myriad of other influences which go outside that field on a daily basis. Your question regarding condensation can be answered by any pupil studying for their physics G.C.S.E. I shall therefore refrain from issuing a detailed answer whilst acknowledging your undoubted technical expertise.

but they are security engineers who need to look at a myriad of other influences which go outside that field on a daily basis.

The basic rules of electronics apply no matter what "other influences" come into the equation. It gets bad when sales commission and/or profit margins induce "engineers" to bend ( ignore ) the rules of electronics to make the product appear to be better than it is .

Your question regarding condensation can be answered by any pupil studying for their physics G.C.S.E.

it may be 50 years since I got "A" level GCE in physics but we were taught, "" no moisture or water vapour then no condensation is possible ""

When it comes to alarms some sirens have co-formal coating on the entire PCB, some only on the high voltage area around the strobe circuitry and some have no conformal coating at all.

I shall therefore refrain from issuing a detailed answer

Please explain why my physics master was wrong. Too late for him but I welcome the correction of errors in my education.

 

[chaindaisy]

And your point is ?

My point is that my education was and experience is that condensation can only occur if there is a source of water. You seem to be implying that modern education to G.C.S.E. standards is that condensation can occur in the absence of water ( if the temperature is high enough ? )

Dearest Bernard,

In legal circles I too tend to use the term " ... you imply ..." as my precept to gauging a persons reliability as a witness. However, under this particular topic viz; 'quiet siren and bleeps' or whatever, I have attempted to help the gentleman who posed the initial question. I doubt that I was successful to any degree in doing so.

In reply to my question " .... and your point is ? .... " it would appear that your answer is merely a repetition of your earlier post. To which you add the now infamous "... you imply ...". I can assure you that I never imply anything. I state a fact or a supposition which is not an implication. Nevertheless, it is open to the reader to determine from his or her own life experiences whether or not the writer is 'implying' a conjugative route. One person may for example suggest that Dickens is implying something in his writing, whereas another may suggest that Dickens is implying something totally different, yet a third may suggest that there is no implication in the quote, sentence nor paragraph. Unfortunately, the onus is on the reader, the reader's state of mind and the events which have moulded that particular reader's life. I tend to find a degree of malice in the mindset of persons who repeatedly question, repeatedly suggest 'implied' comments, and refuse to budge from a position they find themselves in, whether they are right or wrong, and invariably wrong.

I believe I have answered any arising anomalies in earlier posts, and amongst them was a reply to yourself regarding condensation. Unfortunately, I did not have the pleasure of meeting your 'physics master' whom I am sure had your best interests at heart. You are aware that I have not met him, of course. Therefore, I am neither liable to yourself nor your physics master for the purpose of benefitting yourself with an explanation of any kind.

Now, you would readily accept that this is a forum for D.I.Y. problems and not a soap box on which you or I vent our personal aspirations. I would suggest that, in such circumstances, we allow it to be used for just that; D.I.Y. problems.

Rather than allow you to leave in total anguish, perhaps with your acute electronics and physics knowledge you would care to furnish the site with the chemical symbol for a) carbon dioxide b) nitrogen c) oxygen and d) air (if there is such a symbol). I re-iterate the fact, no I do not imply it, that every pupil studying physics G.C.S.E. shall qualify the fact that " ...rain has nothing whatsoever to do with condensation inside a siren housing, niether does humidity..."

Be kind to yourself, you have nothing to lose.
