How to Join Alarm Cables

["JonS" <semi.jon@xxxxxxxxxxxxx>]

I want to create a distribution box for my alarm cables so that I do
not
have to disturb the main enclosures to make minor changes (Idratek modules
have inputs on relay modules).  I need capacity to join about 100 cores
(i.e. 50 joints) but some are solid other stranded of varying diameters as
I
have a mix of alarm and Cat5e cable to join. Some are carrying power (12V)
others signal.

I've looked at various IDC connection options but am confused by the choice
and how to join the cables entering and within the distribution box.

Something like this looks suitable

Would I punch down each incoming wire on a separate contact/IDC connector
and then jumper between them into the same IDC connector or would the
jumpers go into an electrically linked connector within the same block?  I
think I will be punching the cables directly together as this will give me
adequate flexibility - is this a no-no?

For 12V distribution could I put several cores into the same IDC connector
or best to use chocolate block for that?

Alarm networks must have this same problem when they are moved / extended
but an image search only shows new connectors rather than ones in use, or
else are of huge installations where the detail is missing.



Many thanks
