IR radiation is naturally ocurring and its sources are everywhere. Now you
have introduced facts not in evidence to blame someone not posting to defend
his or her position.
My post below didn't say anything about the IR. I suggested that the occurrence
of the problem across multiple sensors suggests to me a wiring or brain fault.
Period.
You have followed the same schema in your post that you
have blamed on the installer as faulty and you have not solved the problem
either.
I didn't say the installer was "faulty", I said his troubleshooting was half-assed.
The circuits in a PIR detector are for the most part pyrolytic
element(s) with a delta t and delta T circuit. where t=temperature and
T=time. I have had courses in physics. I detect pure physics genius in your
post. I hope we can enjoy a through discussion from you on the vibrational
energy transfer and reaction of vibrationally excited molecules at surfaces.
Please preface your remarks with your CV and all of the academic credentials
you have garnered.
I detect an extreme lack of reading and compresension skills on your part. Go
back and re-read my post and tell me where I said anything about the physics of
infrared detection.
Or instead say it is nearly imposible to figure out who
or what is to blame from the very limited information available.
I'm not blaming the installer (who in this case is apparently NOT the ORIGINAL
installer either) for the problem, I'm saying he didn't diagnose it properly and
was likely more interested in simply selling the OP new hardware.
Believe it or not, this DOES happen.
customer is upset over a bill and doesn't want to pay it most likely, and
that is more the focus of his question.
Of course it is. The ensuing discussion is ostensibly about whether the bill
he's been handed is legitimate.
My take is, the installer who's billing him has failed to correctly diagnose the
problem and has merely treated the symptoms, and should not be paid for an
incomplete job.
He has not been cheated in any way I can detect from the information given.
He's been sold equipment he probably doesn't NEED, and he's being billed for
work that wasn't properly done (ie. determining and FIXING the problem).
Hey Jim, does this Matt guy do any real work in this industry?
In fact, the company I work for specializes more in CCTV, although we do do the
odd alarm.
Experience has nothing to do with common sense. Common sense says that this
installer has done a lousy job of troubleshooting, has apparently not found the
actual cause of the problem and is merely patching up the symptoms, and from
that may simply be interested in selling the OP new hardware (probably with a
healthy markup) as a "quick fix".
