No nothing like that just some drilling , plasterboard put up .

Hi guys need some help . Urgently . Recently had some work done in my house and the fuse spur for the alarm has been blowing every couple of day for passed week. This Pir I’ve noticed has gone red also so was wondering if this could be the problem cause all the others have blue lights. If this cable was broken it’s only 12volt anyway so didn’t think this could be the problem the fuse in the spur was 13amps also , thought it should of been a 3 or 5 amp . Didn’t take the MCB out just blew the fuse . . Can anyone help me out . Many thanks guys ,
