Thanks fozzies, will give this a try next time im up there. Regards Chris

Hi, do you mean the module or the pabx?

Yes I think your right about getting in a pro, I think I've gone as far as I can with this now and your right this was just a favour and it's become a royal pain in the butt !! Time to let the owners deal with it and spend some money me thinks. Well thanks for all your time and if you pm me your details, I'll pass them on....if you want !! Regards Chris

Hi, the pabx was reset about three times during the maintanace visit, but the module only seemed to work after the first pabx reboot, but as I said for just half an hour.

Just a quick update:- The telecoms people came today and checked the line from the module to the pabx with a butt phone, which showed no faults on the line. The Samsung system is a digital system and is quite new and does not suffer with drifting frequencys (according to the engineer). When the engineer rebooted the pabx system, the module worked for half an hour as it should, but then went back to being intermittant. The paired cables between the module and the pabx were swapped with a spare pair and retested with the butt phone, but the call button was still intermittant. The paired cables show a voltage of 42v from the pabx to the module, the voltage from the psu is a constant 12.3v the call switch is is functional in itself and I am now at a complete loss as to what it could be!!

I found a profile feed and left a message there, Reckon a wife beating is in order but she has the rolling pin lol

I forgot to say, yes the number the module Yes im of the same opinion about coinsidences. I'm not an installer and it's even harder to get any information out of Urmet, but they did give me the programming guide for the module after asking nicley! but it has been an up hill struggle, especially as information will only be provided if you are an installer and you subscribe to their payment system. I wouldn't mind but I got volunteered into to this by my wife! for her friend...as a favour lol Like I said Thanks again! and where do I find your thanks button? as I am not so familiar with this site as of yet...but I get the feeling I will. Chris

Hi, yes I did check there was voltage across the switch when it was pressed, and yes there was, it's my fault not explaining myself...sorry. When I programmed the module, at first I did not know the group ext no. so I checked it by programming it with a known ext no. , once I knew dedicated group number I put that in and it would ring all the phones with it's special ring, athough thoughout this process the call button was intermittant ! I made sure that dial had a 2 second pause as you quite rightly pointed out about the pabx, as apparently most systems can cope with 2 secs. The telecoms guys are coming out to run a scheduled maintanace next week, so I shall get them to carry out the tests on the ext to the module with their test phone and hopefully that will identify if there is a problem with the ext or the pabx. It just strikes me as strange that the new module has exactly the same fault as the old unit, if indeed it is the module at fault, also the power supply seems to power the keypad entries ok, they never miss a beat so I suppose it does point to the telecoms side, im just wondering if there is a parameter in the programming of the module that I have overlooked or whether i should double up the power cables to the module to just be on the safe side. I really can't thank you enough for taking the time to answer and explain things. Chris

Thanks, I look forward to your post later.

Hi fozzies, I have just been to check the continuity ( which in fairness I had not done to the new module) across the call button and they make and break every time, the voltage into the module is 12.3v and is constant whether the button is pressed or not, I did notice that the psu is not that dissimiler to a laptop psu, being fed by the mains via a figure of 8 cable, which in turn feeds the intercom module and 2 keypad modules in parrallel, is this a standard psu for this kind of setup? as I'm now suspecting that there is a possibility that when it was installed just over 3yrs ago, it just about coped but is beggining to fail due to overload! It's a weird one because it's almost giving the symptoms of a corroded cable, sometimes working, sometimes not. I think I will replace the psu with something a little more substantial and replace the cables from it to the intercom module also. The pabx system is realitivley new Samsung unit and after talking to the installers of this, they assure me that if it works in one direction it will work in the other direction as it is just a 2 wire system, and thinking about it, when the module seizes the line, the connection is always made. It's just getting the module to do it's job and seize the line on the first button press every time. Thank you fossies for your helpful advise. Chris

Hi I was wondering if anyone could shed some light on a problem I am having with an Urmet 1145/1 intercom module. The problem is it has an intermittant call button, it requires 2 or 3 pushes for it to connect. Thinking the unit was faulty, I replaced the module for a new one and reprogramed it, but it still does exactly the same thing ! I have checked the power cables to the module are providing the correct voltage etc, which they are. Now I am thinking there is a communication problem at the pabx system in one direction, as I can call the module every time from the phones in the house, Any help will be apprietiated. Thanks in advance Chris
