    Default Concept 2000 failure

    I have a Concept 2000 installed at my home which has finally failed on me after nearly 20 years of reliable service. The error message I get is "terminal reset....please wait"......the error message does not go off and the alarm squarks continuously....can't do anything on any of the 3 keypads installed. Being a former techie (now retired), I had a go and did the obvious things to reset the controller like power cycling the system with the battery disconnected....only difference this made was for the alarm to go from high pitch to squark. I haven't tried reseating the chips into their sockets, this will be my next step as its possible the error could just be due to poor pin contact. The people who installed the alarm (gone out of business now) installed reed switches on every window and door and also a number of PIR, a setup we would like to retain.

    I know that the C2000 is obsolete, but I'm hoping someone out there can either repair the controller or has a 2nd controller to sell. PM me if you do. I assume this will be the simplest and cheapest solution and all I would need to do is swap out the NVRAM chip.

    Alternatively, can anyone suggest a system to upgrade to ?...

    Unfortunately you'll probably find that the NVRAM chip is one of the most likely components to fail after 20 years of service. Those Dallas chips have an internal lithium power source which has a design life of "no less than 10 years", if you got 20 years out of it, you're doing well

    You'll have to reprogram, but you may find that replacing the Dallas chip and defaulting will "fix" you're problem on the existing board, leaving you with a working (albeit blank) system.

    defaulting will be a big problem unless you take it to CSD and sign a waiver. It then becomes your problem if the factory default fails, this default does not delete all the programming just the installer code back to default setting.

    I suspect you are right about the dallas chip power source failing, would have been useful to have another chip to swap just to confirm the board is OK but I don't.....also don't quite follow why you say I would need to "default" as well, as I assumed replacing with a blank dallas chip would set the installer code to default....perhaps a wrong assumption?

    Default Concept 2000 Terminal Reset

    Greeting's All,

    Sorry to stick my nose in but did something change prior to the failure,
    example: relocated a terminal (codepad), low battery condition, rats in the roof etc.

    "Terminal Reset" is generally associated with a LAN BUS device address issue,
    that is a terminal has lost its address and I have seen this before with a
    cockroach living inside a terminal and causing the terminals address to change.

    If you haven't already, restart the panel whilst holding the HELP button on the terminal,
    this will display the codepads address, best to start from terminal 1.

    A new panel wont help you if your LAN devices are incorrectly addresed (numbered)
    or lost on the LAN because a rat chewed through a clock or data line.

    Best Regards......Pete

    Hi Muttley,

    all suggestions are welcome , thanks for yours.....I got the wifey to hold down the Help key whilst I powered up the alarm, but alas, the issue is still there, same error message and alarm sounding off so I've disconnected ac power for now.

    The problem originated after an inquisitive visitor pressed one of the panic buttons I have installed in the bedrooms (and before you ask, yes...the panic button has definitely been reset). Once the alarm was triggered I couldn't turn the alarm off because the the keypad is unresponsive. I tried the other 2 keypads and they were unresponsive too...actually, come to think of it, some keys did change the characters on the keypad but the "terminal reset...please wait" message kept overriding anything I did on the keypad. So the only thing I could think of to shut the siren was to to turn the power off to the alarm system.
    I've also tried reseating all socketed components but this hasn't worked either.

    So the problem may still be a failed NVRAM Dallas chip or a bad LAN bus components....

    I feel I'm getting out of my depth here so would be happy to pay someone to go come over and fix my problem or can someone suggest a company still servicing the C2000.

    I live in Sydney SW (between Campbelltown and Camden) so if this is within your area please PM so we can tee up a time.

    thanks

    I am in Melbourne so the service call will be a beauty.
    I have a Concept 2000 board if you need it ( postage is at your expense )

    Can you send me your home phone number ( not mobile ) by message
    and I think we can fix it over the phone. I need more information.

    Regards....Pete

    Consider replacing the panel with a Concept 4000LX and a new keypad. Keypads that age often start giving trouble anyway.
    If you have any expanders you might get lucky. Some will work with a dipswitch change. Some keypads can even work with a dip change.

    A multimeter will answer your question, use it to read the LAN voltage and come back to us with what it is.

    Just a heads up for those following the thread.

    Maskitoe and I have discussed the situation and done a diagnosis
    on the entire system and we found a number of concerning issues.

    The terminals are early IRT2000's and not compatible with any other
    IR series panel. They have been wired with CAT 5 and had the same
    pair for data & clock (orange - data. orange/ white - clock), so he was
    unlucky that it didn't fall over shortly after install so the company
    could come back and wire these correctly, we have now addresed
    this issue as best we can. ( split pair )

    We could not get the panel to start even on just one terminal, so he is
    preparing a section list for me and I will program a replacement panel
    on the bench and send it up to him.

    If he wishes, he can send me back the old panel so that I can perform
    an autopsy. (very gory business you know, not for the faint of heart)

    Overall the system was poorly installed by idiots.

    Thanks to all....pete

    PS this may be an interim measure until he can find a local competent tech
    to quote for a complete upgrade to the system. 55 reeds, 5 PIRs so possibly
    a C3000 or Solution 64/ 144 ( existing system has past it's use by date )

    Cat 5 was considered cutting edge in the early nineties :-)
