assuming as you say 0abcd then its not on default codes. But I only know the uk panels and they may have different defaults. I think they are printed on the pcb in the aerial area.
if the code was correct it wouldn't wait for any more digits
The thing is, you might be totally legit in your request but we don't actually know that or have any way to verify it. Also if we were to give this information out then anyone could access it, Obviously then there would be no point in your security system.
