Help to remove A1 AJ600N security alarm

[kal87]

Hi all.
I have just moved into a new property and we have a old A1 AJ600N security alarm which has not been working for a while now according to the previous owner. There is power to the alarm. I want to remove and decommision this alarm completely. The fused spur is located near the keypad downstairs which can be seen in the photo. Would there be another fused spur near the control panel. From what ive been reading online alot of people say the spur is near the control panel, and so i am wondering if there will be 2? I am yet to find the control panel as I believe it may be in the loft. Any instructions on how to remove would be much appreciated

I would say that that is the control panel with an onboard keypad

Oh really.

Any idea how i would remove and decommision the entire hardwired alarm system. It is wired to the consumer unit and is shares a breaker with the smoke detectors.

if you pull the fuse out of the fused spur do you loose the alarm panel and or the smokes?

Ive not attempted to remove the fuse yet, as i was bit sure if there was a separate control panel. Will try this when I am back at the house on Thursday.

Really, would you be able to guide me through how to remove the entire alarm system if its not too much trouble.

Well, they are much like any other.

You need to find out if you have a back up battery in the external bell box.

Have you discovered which local fuse kills the power to the alarm panel?

 

[kal87]

The alarm is connected to the CU on a breaker shared with the smokes detectors. There is a fused spur next to the control panel, but i will check tomorrow to see if it also knocks out the smoke detectors if removed as someone has suggested may be the case.

Some older external bell boxes don't have a battery and some which do may well be goosed.

Burglar alarm panels have two sources of power. Normally run off the mains, if that is cut off, there is a battery, usually in the main panel, that takes over for a few hours. In most modern systems, there is also one in the bell box, so that even if the bell box is electrically detached from the rest of the system, it will carry on sounding.

The issue is if you kill the mains to the panel and remove the back up battery inside the panel, the bell box might start bleating, in which case you would need to get up there and administer violence to it, I mean get it to shut it up.

If you are lucky and there is no battery in the bell box, or it is goosed, when you remove both the mains and the back-up battery from the burglar alarm panel, the bell box should stay mute.

Please practice safe isolation.

If you pull the fuse what happens.

you can always push the fuse back in if a problem occurs

I will

Try this tomorrow, and try to get hold of the manuals to see if there may be a battery in the bell box.

you need a professional I think to do this safely.
