"Whats to stop someone from replacing the fuse in the spur"
Well yes take your point but this is where the definition in the law is a bit of tape across a mcb is not a barrier but having to use a screwdriver to unscrew or pull out the spurs fuse holder is seen a physical act and deterant so then Joe Public does not have an excuse because he or she could use a screwdriver to open a CU socket, light switch and so on when the law says they should know better.
Also one other point when I got into alarms 26 years ago the majority of burglar alarms were rented mostly by business or a household who could afford it. I was a time served spark but most of the guys I worked with were not sparks so hence why the dodgy mains supplies although now there is a spur fitted and the only problems now is there is a 13A fuse fitted. If you send me your email address I will dig out the check sheet I created to service an alarm system and if you need any more info drop me a mail.
