Hi It depends on the model run of the accenta8 you have but contrary to posts so far ADE default user code is 0123 not 1234 All models lock up with mains spike caused by flat backup battery as the psu can't cope with the added current. Depending on run power down mains & battery power up mains only and within 5 secs press reset twice panel should bleep twice and default;or power up battery only and panel will reset to default on earlier models.IIR the accenta 8+ would only house a 2.3ah battery whilst the metal boxed remote keypad version would accept up to a 7ah. If you post type ( remote keypad,metal box,plastic box with keypad.) I should be able to dig out the manual for you. HTH CJ
We had a short power cut today and the when the power came back up the alarm went off and could not be controlled, so I've taken out the fuse.
I understand that the fault lies with the back-up battery failing in the main Accenta unit - the system was installed in 1999 and the battery has not been serviced. It's quite a large lead-acid battery I see they are on ebay for about £8.
I'll get another of the batteries - but the question is when I install and restore power is the code lost and if so what's the procedure for getting it back to normal? Trying to figure it out with the alarm going is not easy...
