I have recently moved into a new property which has an Eurosec CP8L alarm fitted. I undertand that the property had been empty for some time as it has been completely renovated. The user manual for the alarm was conveniently left nearby. A couple of days after moving I tried to use it. I noticed that the LCD displayed the message "Mains fault". Anyway I decided to give it a go assuming that the code left would be the defualt code. This did not seem to be the case as as soon I pressed a key, the system becamed activated. The main door was open as my parter was doing something and the whole thing went ballistic. The default code did not work at all. So I could only open the "fuse box" (no fuses there, just wires) and disconnect the system. As it was still blaring, I ended up opening the main box (the one with the anti- tamper spring) and disconnect the battery.
Is there anyway I can do a full reset of this alarm or should I call an engineer to do it?
Thanks in advance.
