Hi, After some help.

I have 10 year old Eurosec alarm system,  and when i went to change the internal battery i noticed a loose Blue wire, which i believe is the Trigger wire from the external alarm?.

Any idea were this should connect to? I have also noticed that the external alarm has stopped working.

 

the bell trigger connection

There are probably many wires that are not used inside a control panel do  a bell test if it works then its not a bell wire. Then set it if it sets then its likely not a wire in use 

I agree with PJ, was it stripped back as if it should be terminated somewhere?

Bell test works and system sets okay

I would guess that wire was unused then

If you want to keep your system operational I do hope you change your battery more often than once every 10years
