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...

I'm pretty sure that the code should not be lost.

If however it has, it may have reverted to factory settings (most likely
1234 or 9999).

On the downside, when we had a power failure (actually the supplier
changing the main-fuse and holder) and the alarm battery had failed; the
alarm somehow got fried and never worked again.

Thanks - I think you're right and it's in non-volatile memory. The
instructions are very poor.

I wouldn't be surprised if we get the same. We never use it anyway.

I now see the installer is still in business so I'll ask them for a
service call quote - may as well give the house it's added value back.

My guess is that after the 1234 or 9999 engineers/programming code one
step in the subsequent setup was missed because of badly written
instructions in the manual.

Your diagnosis of the problem is probably correct.

When I replaced the battery in mine I also removed the mains power at
the same time. On applying the power the alarm was completely reset
along with a two tone beeping from the control unit, but no external
alarm. Entering the engineering code stopped the beeping and allowed a
set-up sequence.

You will need the instructions for your alarm to set it up. My original
instructions were a translation from Chinese by someone who spoke no
English I deciphered them when I first installed the alarm and
condensed around a dozen A4 sheets down to a single page.

No, it would not set or reset with either the originally programmed or
factory codes and would not enter engineering mode at all - so no steps
could be missed. It just locked up totally and would not accept any key
entries (wouldn't even beep on each key press).

Powering off and on again gave no improvement.

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.

Having checked the list of Accenta models the 8 is the "pig" of the litter.
Reset is as follows:-
disconnect power,battery & mains.
Remove all wires from terminals 17 (PA) and 27 (set+)
fit a link wire between these two terminals and connect power.
system will power up with no alarm
remove link and refit wiring.
Keypad will show any open zones.
when all zones clear and lid tamper clear panel will beep and go into day
mode clearing NVR.
User code 1 is now 0123 @ eng code is 9999

apologies for crashing the thread and I hope the contributors are alerted to new comments...
but I need to do exactly the same thing and I'm unclear on when to reconnect the battery
I need to reset the engineering code to the default value and I want to change the battery at the same time
.. with battery connected or not?
.. or connect battery here?

2012 I think the list of old posts must be catching up at last....

Hi CJ, would be very grateful for some help, I have disabled the alarm on my
system using your method removing wires from terminal 17 PA and 27 set and
putting the jumper wire in, which worked perfectly thankyou, the only
problem is now I want to reactivate it, any ideas? thanks Jim

just saved us a call out . Thank you.

Changed sensor now no sensors are working

What kind of sensor? Magnetic switch, PIR etc.?

What was wrong with the old sensor?

When did you last replace the battery in the alarm control panel?

Got an accenta8 and it gone into Tampa mode and locked down keypads etc.
Changed the battery with no effect.
With the battery disvonnected and taking the fuse out the alarm goes off and the pads work. So looks like power is getting to the main board

But still nothing with battery and power?

Any ideas before I call an engineer.
