Hi all, I fitted a new washing machine wall switch, which went ok, 5 mins after completing the job and exactly when I switched off another plug upstairs, the internal alarm went off and the internal power to the alarm panel was cut. The fuse for the burglar alarm has not tripped. Then at night the external alarm had gone off for about 10 mins then stopped. Not sure what will happen next. Where I stand now there's no hard wired power to the alarm. Any ideas plzzzz before I call the alarm guys....
