accenta8 mini, was playing up last week all zones were lighting up when i tried to enter code and would not let me set the alarm. Solution was changing the internal 12V battery, everything was working fine for 3 days then alarm just went off by itself, entered the code and it switched off but stayed on tamper and would not let me reset it. Turned the system off from the mains, alarm goes off, can enter the code but again stays on tamper and wont let me reset it. Disconnected the internal battery but still the same outcome. Checked the fuses and all working. The box outside is flashing due to the tamper light on keypad. All sensors are working.
Any ideas anyone?
