House alarm goes off when power comes back on

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. I hope you have found this video
