Sierra's re-dialling Constantly
Learned Colleagues,
Has anyone come up against the old C&K Sierras redialing constantly and not hanging up, costing heaps in Ph Calls?
Having a number of these panels playing up at the moment. Seems it was also a problem earlier in the year
and Telstra admitted in some ques to having caused the problem through upgrades in some exchanges for the NBN.
I initially put it down to the receiver but it is taking a number of other panels with no problems, with multiple line cards in rotary and
it is from a specific area of the country at a time, not all over.
I have listened to a number of the panels and the Ademco Contact ID Protocol sound fine with handshake - Kissoff sounding good except for a bit of
an echo which could possibly cause a bit of confusion in the transfer. I am yet to get a few readouts from the receivers, but all sounds OK.
I have been told there is a mode for Sierra panel daillers,but can find no info and Honeyill (Honeywell)have no answers.
Any info would be good.
Thanks

I remember the 238l 's doing a similar thing years ago,
I put in about half a dozen and eventually pulled them
back out.
Piece's of crap they were, I returned them for credit.
You might have to put the sierra's in " WHEELIE BIN MODE "
animated laughing thing here [-]

Your best bet would be to pull it out. C&K Panels are considered end of life. We had an issue similar with a Sierra, Rather then trying to trouble shoot it we simply replaced it with a new panel. We've slowly been pulling all C&K Panels out and replacing them.
If there was any confusion with the transmission the receiver would not kiss off the signal. If it kissed off each transmission the alarm event will be in the automation software. I would think the problem is at the panel end, with the panel not recognising the kiss off tone, and hence resending the data as it is designed too do. This will all be to do with the PSTN line configuration in the exchanges.
To confirm this you will need to go one of the sites with your phone butt and listen to the panel communicate with the receiver. Maybe you could upload the panel event log which might give some indication as to what is happening.
No problems with COntact ID Protocol - Handshake and kissoff all ok. Have listened to a number of comms, remember all other panels OK - Bosch/Risco/Paradox on Reciever.Originally Posted by kiwitech
That is what I think. Measured line Voltage at 55.2v at panel, but I can't find any specs on Sierra Dailer tolerances. Also at the same time our ADSL at home has doubled it's throughput.
Maybe Telstra has beefed up their line voltage for impedance in the area.
I used to have a pocket base emulator many years ago and would love to have one now.
To others that have suggested Binning the units, that's too good for them, I think they will used as a chook laying box's, with circuit board in tacked.
The shameless people that distribute this garbage
shold be drowned at birth.
Your posting of the issue at hand had me thinking about the worst
panels that I have had the disgust to work on and program.
Probably a good subject for a fresh thead, here are some samples:
All C & K panels ( Dualtecs were pretty good )..
Seadans fabulous DMP panels (just lacked the U )..
I did beta on the Soluion 40 and warned them (deaf)
IEI E86-8's (ahead of it's time but would die early)
IR Concept IQ ( were was the IQ, I never found it )

The cost of a modern panel is such that you'd surely spend more on diesel driving to the site and a couple of hours screwing around, than simply shouting them a new one.
Even if you got it working 100%, at its very best the end result would be a polished turd.
If you want instructions on that:
We've been coming across a heap of DS Panels lately. They are absolutley garbage, not to be confused with DSC panels. DS (Detection Systems). Terrible things.
My most hated panels:
1: Concept IQ don't know what Inner Range were thinking.
2: Solution 40 another panel that never worked like the IQ if it did work it was not for long.
3: C&K while they work in my opinion the worst to program.
4: Moose Alarms have not seen any in Oz which is a good thing, lots in NZ
5: Texecom only cause that make noises like my dishwasher
Just an update.
Telstra have admitted a problem, came down to a deal with Optus and routing of calls.
Yes we are upgrading a lot of panels for the next few weeks.
Worst Panel ever/ever
Wormalds Surveyor wired in single core phone cable. Used in NAB,s
Chubb Custodian Bank series. Used in ANZ'
Vanguard III used in some banks with a Ness DSR module, Dick Smith Camera Counter and a million relays.
Revolutionary Panel of its time,
Ness 5000 - Just ask Warren.
Best Panel
Concept whatever.
But I must say the latest Risco LightSys is a great little Panel!
