I'm not entirely sure of how the link works now... do you have any diagrams that show all the connections of the 2? If I were to have the second bell box with an independent power supply (it would use the ho+ and ho- is that right?) so i'm not sure how that would work

arh ok thanks. I missed off by accident as we don't have it yet, but we were going to add an auto dialler to the unit. Hence running short of that 1 extra input. Just to confirm, do you mean both wired with a tamper and switch, but 1 box supplied by a separate 12v supply+battery back up?

We were thinking of 3 PIR's and 4 door contacts, then the 2 bell boxes...

Thanks for your reply and advice! It was just for 1, 2 at maximum door contacts that I was going to add. along with the alarm box, do you think it will cope? Regards

Hi, Forgive me if this is very obvious, but I am new to wired alarms and just want to confirm in case all goes wrong... We purchased the Castle Euro Mini alarm from you recently, we are looking at installing it but had a query, if we want to wire more sensors than we have inputs in the unit, can we wire them in parallel in the same way you would wire the Tamper circuit in double pole wiring? then if so, is there a limit or recommended maximum for sensors and cable lengths etc? Our other question, due to it's position, we purchased a duplicate genuine alarm box (not a dummy). should these be wired in together to the same terminals or is there another way? Again apologies is these are very obvious questions but your advice would be appreciated. Many thanks
