The local electrician near to me said adding a fuse connection unit is ok as long as you do all the tests and paperwork. He also said he would show me what needed doing. Which is also what i was told on the tavcom mains compliance training. I was also told being competant is about showing you have done training and been shown and can show you can do all the tests. You do need a meggar tester (thats a brand name) fluke also do one If the site failed the earth test for instance you would need to abort untill a sparky had fixed any faults you found before your install Adding a new circuit is also sparky land i.e fitting new cable to a new mcb Also you cannot add to a circuit without a RCD you have to test the RCD, which you have to test trip's correctly using your slighty expensive new toy (meggar or Fluke others are available) This is all i have been told on a course or in person, I like to listen and make sure what i am going to do i do correctly. I now have a part p tester which is great, I checked my earth and RCD and they work fine so my flat should burn down yet unless i cook something I suspect sparky's would like to keep doing even minor works as it's money in their pockets not yours

Ask the seller?

The keypad will display active zones and if it's just picked you up does tell you that zone is preventing arming to make you check you have not missed something what happens if with the zones for the pirs set to guard access Enter you code, do you want to arm ( Yes ) Display showing Zone preventing arming Pir? Then press yes again and leave. Does it set or not and what happens when you come back in does it (entry) and disarm and show no faults ?
