How to turn off burglar alarm & decommission

If you're wanting to turn off a home alarm, and remove the power and fully decommission (forever!) a burglar alarm - then this is a short guide on how to do this. Key steps are:
- Locate your alarm panel
- Locate the fuse spur
- Remove fuse from fuse spur
- Open alarm panel
- Remove the x2 terminals on battery

Can confirm this is exactly how it went on our Mercury alarm. I think the battery was going bad and it made an internal alarm every hour (starting at 5am this morning!). Disconnected the fuse, removed the cover. The tamper went off. Entered the code on the key pad to stop the tamper alarm. Eventually plucked up the courage to disconnect the battery. The external siren then went off for about 10 minutes. Done. Thanks.

The instructions were simple, to the point, easy to follow and VERY EFFECTIVE! Thank you very much.

Hello mate, my elderly parents have been suffering from power cuts and their alarm woke up the street all the time causing them considerable stress. This has solved the issue and I thank you.

Brilliant. Exactly as described and very simple to do. Thankyou so much . Just saved me the £190 + VAT I was quoted for an engineer. How these people keep a straight face when charging so much for such an unbelievably simple task is beyond me!

Worked like a charm thank you!!! Followed your steps. Switched the mains back on and the outdoor alarm stopped in less than 15 minutes.

Cheers this worked the company that had a contract to service our alarm said they’d have to attend (call out charge obviously), it took me literally 2 minutes following your instructions thank you very much. Obviously the alarm ringing for 20 minutes annoyed the neighbours but they are an ignorant bunch of self centred muppets so two birds with one stone.

Thank you very much for this extremely helpful video. I was just about to call an electrician, when the thought of looking on good old YouTube came to mind. You've saved me money. Thank you.

This is a great and useful video. For my decommission of the VISONIC alarm, I added the unplugging of the backup battery cable. I also turned off the security alarm switch in the main box.

An absolute life saver this video. Alarm going off in the early morning but haven’t used it in over 10 years. Followed guidance and everything is quiet!!

Thank you so much. You saved our sanity ❤

This worked for me, thanks for the help! I have 2 questions, 1. Once the bell/siren has gone off, is that it off for good or is there anything that could set it off like a power surge? 2. Is it safe to leave the spur with no fuse in it long term, does it need to be isolated on the main board too or disconnected completely? Thanks

[furstyferret]

Just been up a ladder ripping wires out the siren, just seen this now! 🤦🏻‍♂️😂

Ive i switch the power the electric off on the main box to the ehole of thr houd, will this set iff my home alarm? Also if then enter the code will it turn off the alarm siren

Reason im.asking as have replace same gang wall sockets

[rahimqureshi]

Do you just need to remove the fuse? Is it safe to disconnect the cable from the fuse spur to the alarm panel after you remove the fuse?

Are security alarms connected to mains power supply? I'll be decommisioning my security alarm tomorrow and will be removing all sensors and any wiring that comes with it. Thanks

[hoverbovver]

I need to move a sensor due to house renovations. It will take about 5 minutes to snip the wire, extend it and reconnect it. Will the antitamper trigger the alarm even if I disable that zone? And will it fall silent after 5 minutes or continue to scream until an engineer enters the maintenance code?

[TheMattprune]

Why does the alarm still go off if the battery and electrical fuse removed? How do you stop the alarm going on for 20 minutes as this might annoy my neighbors. Will it be safe to remove the alarm at this point?

I have a Risco 2 system which is wireless with the only part hard wired the main panel and internet connected.
So sick of having to replace the batteries at around £60 per battery every 2 years and subscription costs of 30 per year to Risco cloud that's before the annual service of around £100 per year i have decided to decommission and resell the whole system. in favour of a complete hard-wired monitored one. any thoughts and advice on how to best do this would be appreciated, can i do it myself or is it wiser to pay an engineer to remove the system?

I’m currently trying to deactivate my challenger pa28 alarm. I’ve taken the fuse out but too scared to disconnect the battery incase it doesn’t turn off. Will having it disconnected from the mains for a day or two flatten the battery?
