If your burglar alarm is sounding after there's been a power cut that
is probably due to the backup battery. The good news is it is extremely easy to
change it. It's quite easy to test the battery all you need to do is switch off
the power to the alarm and then when you restore the power if the alarm sounds
you know that the backup battery is dead or it's not working very well. This
battery should kick in once the power is cut to the alarm. It's very common and
you will notice that if there's a power cut in a large area that once the power
is restored a lot of burglar alarms will be sounding. You can fix that problem
quite easily simply by replacing this battery. These batteries do vary in price
this one was approximately £12. The important thing about the battery is
getting the correct sized one. Most of them are 12-volt but they do have
different amp power ratings you can see that this one is 2.1 amp power.
If you get a smaller amp power rating battery it will be a lot smaller so
really the only way to tell which battery you need is by having a look at
the battery already in there. In this video I will changing the battery on the
Accenta panel which is the same as a Optima these are both made by Honeywell.
If you're lucky you will have the engineering manual like that and if
you're lucky it will have the engineer's number in there. If you don't have that
you'll just have to do it the difficult way remove the panel and then input the
number to silence the alarm. But with this particular alarm we do know the
engineering code so we're going to input that now. So I want to press P and
then 9 9 9 9 which is the default code and you can see that it's gone into SOS
This actual panel is now in engineering mode which means that we can safely
remove those two screws. Once this panel drops down there is an anti tamper spring
behind there which will normally put the alarm into the alarm condition. So we
can quite safely remove this panel now and swap the battery over even
with the power still on. If you can't get the alarm into engineering mode it's a
good idea to have somebody at the remote keypad
to input the number to silence the alarm because as soon as you open
this panel up it will go into tamper mode. So we are just going to undo the two screws it's a
bad idea to switch the power off when you're doing this because if you do as
soon as you reconnect the new battery the alarm will go into the alarm
condition. It's a good idea to put your two thumbs over the two screws when you
pull this down then you don't lose the screws. So we have now safely exposed the battery
the only thing you need to be careful of in here is touching anything
on this side where the transformer is because that is where the power goes in.
But you can quite safely remove the battery, I'm just going to pull that out
and unplug the two terminal connectors. We will then get the new battery ensuring
we've got it the correct way around and then connect up the positive and the
negative and then we can push that back in there ensuring we don't trap any of
the wires. Now all we need to do is replace the front panel.
We're now back at the remote key pad we simply need to press the X button and
that will take it out of engineering mode. You can now use the alarm as you would do normally.
