Da Abacus 15 Installation Manual
As Nova says this does seem like an older panel pre molex pins thats maybe had a software update thats why your getting all the digi programming you cannot miss the pins and you need them to plug the digi on only using two wires ie your telephone line connection thats why its called two wire mode if you have no molex pins and there deffinatley not on the back side of the p.c.b I dont think your gonna do it buddy.Garry.Hes put a picture of the chip on page 1 Pete it says Abacus 6 on the pcb board and Abacus 6 R on the chip.

Just moved into new home fitted with this type of burgular alarm. Cannot afford engineers visit as out of work at the mo, and they don't want to help otherwise. Alarm panel seems to function in setting and disarming the alarm, with normal tones from the house internal sounder during setting/disarming, and when tested by opening the door.

Abacus Manual
The outside alarm box doesn't seem to work at all despite a neighbour saying that before we arrived that it had activated outside once and turned off after a while. We have the manual and a password code (but maybe not an engineers code). We cannot set the time on the panel or access any of the other test functions. The manual tells you to go to 'set system' mode and say 'no' to display 'omit zone' and thereon to the 'program menu'. Unfortunately, when we say 'no' it just goes back to 'system off' mode' and doesn't allow us into any of the program/time/system test menus.
How To Reset Abacus Alarm
From what you have said you have not got the 'Master User Code', that would be needed to change the time & date and access the other bits you mention.If you don't have another code to try, you're stuck.1st, if you have just moved in, the correct codes should have been supplied, at the very least the Master User Code, not a 'User Code' as you have.Go back to the agents and ask them to get the correct code from the vendors. If they can't help it will be the responsibility of the vendors to get the alarm company to attend and re programme the code to ones that are usable, after all you paid for a working system, didn't you? It doesn't work if you want to change the parameters, does it!2nd, It is a very easy panel to default the codes and programme new ones, don't be fobbed off if you have to get someone in, find someone else.Good luck, this can be sorted easily. Many thanks for your very quick and useful reply - I believe that the alarm was originally fitted several owners before and we bought from a lady after her divorce settlement so not keen on chasing back on this - she had said that she believed the alarm was working OK but hadn't been using it - she gave us a code which was the only one she new, which indeed may just be the basic 'user' code.We have both the operator instructions and original installation and programming instructions.
Abacus How To
In the latter there is a section on 'factory defaults' which is said to be a section on a 'procedure if for some reason the programmed master or Engineer code has been lost or forgotten'. This entails de-powering the system completely, including the battery, and then following a start up sequence. This sounds like a worthwhile route, once I've followed through the tech jargon.cheers again.
