Hi Phil, yes exactly as you describe.

Many thanks for this info, just one point do I need to keep the wire colours together, by this I mean can I remove the existing yellow wire from the terminal on the panel and twist it to the new blue one and then put the new yellow wire into the tamper terminal, in the panel, so I still have one yellow and one blue wire going to the terminals in the panel (I hope this makes some sort of sense to you).

The alarm loop will be fine as you describe, the tamper loop needs to be wired in series. ie imagine a loop starting at the control panel going to the contact, from the contact to the next contact and returning to the control panel. In practice to do this take one of the existing tamper cores from the tamper terminal on the control panel, twist this with one of the cores going to the new contact (insulate and don’t connect to the panel) and take the return core from the new contact and connect this to the tamper terminal which is now vacant.
