"False" alarms on wireless alarm systems

I have never been in a situation ever where I could not properly commision a system because spurious false alarms were occuring.

really, you do quantified signal tests before every install? I take back what I said.



oh, wait, no you don`t.




your only getting flake because your so sure, when actually, your wrong

They are not "my" facts, they are facts of radio transmission systems. If you have no experience any of the problems that beset radio communications then I would suspect you have not followed up many or any of the installations. Or the users have not been aware of the problems being there in thier system. Have you ever disabled the jamming detection circuit to prevent false alarms ? ( as you recently advised as way to reduce false alarms ) If you or the users have dis-abled it then that system could be totally useless as an alarm system if there is any source of radio signals that block ( jam ) the siren's receiver when the intrusion occurs.

Which is exactly what people are trying to tell him but to no avail.

Maybe the signal is being blocked by something :(

Co-incidently one of my clients is today arranging for a 14 day monitoring of wireless activity in the area where he is commissioned to install a radio comms system. This is to ensure the system ( with its own licence ) will not interfere with existing systems or them with the new system.

This monitoring used to be person(s) sitting watching a radio frequency spectrum analyser screen and logging with pen and paper any transmissions that could affect or be affected by the planned installation. Now it is all automatic.

No, I am just letting others say what I have been saying for eons it seems.

Reason for not posting sooner also is I went out to check a job out then decided it was too nice to sit in the office and went to the river and hired a boat for the afternoon. Suffering now (Row boat, fancied a change) and not enough sunblock!!!!

Thanks Bernard, I was going to use that quote about the car fob myself. However you beat me to it. Rather funny it was posted as this discussion was going on.

So as the discussion has show you have no understanding of "wireless" how it works, the frequencies used and why. You do realise Yale are on the common range of car remotes. Graded systems moved a while back and although still possibly susceptible, they are far safer and run anti jamming reporting. Two way comms.

But glad to see your being taught, perhaps you will actually retain some of this, even investigate how the items you fit actually work. Rather than take things out of a box and stick them to walls.
This has been the only issue I have had, not with you personally but your lack of understanding which then makes you think DIY equipment is comparable to professional equipment.
Personally I would be ashamed to charge money to fit DIY equipment. And have always refused to do so ( You would be surprised. how many do phone and ask). Actually I bet your not, hence doing so. Why I asked before if you wait outside Ikea with a tool box :D
 
Sounds like a nice afternoon. Hope you enjoyed it.

I have never said the potential for problems doesn't exist only that it only occurs very very rarely if at all in the ebvironment I work in.

More accurately:
With your limited knowledge on the subject and even more limited product, you are blissfully unaware of the problems that exist and do occur.
 
Alumni, out of interest, how many domestic burglaries of UK homes do you are believe are carried out successfully as a result of RF interference with wireless alarms?

And how many false alarms, would you say, as a result of RF interference with wireless alarms?
 
And out of interest, just how do you think anyone will have accurate figures to make any sort of safe statement?

And before you start playing your usual semantics, think a little wider than yellow toot, but then, that puts you in an area you are unfamiliar with.

..and so are the homeowners. Yale are still safely selling the product not having ever failed a trading standards fit for purpose claim.

and if thats not trolling, I have no idea what is.

this one however is answerable - of our reported overall activations last year 1.12% we`re the result of systems detecting jamming whilst set, and 3.96% we`re systems detecting jamming whilst premises occupied

at a guess the figure if radio only would be a factor of 10 higher

Remember to include those burglaries where the alarm did sound but local people ignored it as "just one more false alarm". That factor could be significant in areas where previous false alarms having been caused by interference triggering the jamming detection circuit in a non compelled ( one way only ) wireless alarm system.

Were these systems using 433 MHz band ?
