RE: Looking for Patchpanel

["Paul Gordon" <paul@xxxxxxxxxxxxxxxxxxxxx>]

Hi Mike

The important point was to bring the mass of connections away from the
Comfort terminal blocks - my current panel has *loads* of cores twisted
together going into the 12V/Com connections for example, and all the unused
cores are also bunched up inside the panel case... - all *very* untidy, -
hard to actually get the cover back on the panel (so I leave it off!), and
doesn't inspire confidence in the reliability of the connections (although
touch wood, it hasn't caused any problems so far).

Krone blocks or patchpanel - the principle is the same, - just to get the
connections outside of the case and into something much more manageable. -
I suggested patchpanel because they are cheap, easily available (I imagine
Krone is too, but I've more familiarity with buying CAT5 stuff). Also,
because I have structured cabling already, it seems to be more in keeping
with the paradigm... - as well as the permanently wired zone inputs (which
I agree probably won't change after initial connection), it means I can
quickly and easily install another Comfort input or output anywhere in the
house where the structured cabling reaches, just by plugging in and
patching... - I want to put a flood sensor in the kitchen? - didn't wire
for one of those specifically? - no problem, just wire the sensor to an
RJ45, plug it in to a nearby faceplate, and connect it to the zone just by
plugging in a patch cord back at the panel... - (because unlike some
people, I *did* put enough CAT5 outlets in the kitchen!!) Same with output
zones, - want a comfort controlled relay in the boiler cupboard? - not
previously wired for one? - again no problem, since I have a 2-port CAT5
outlet in the boiler cupboard, so again I can easily use the existing
structured cabling to connect something to Comfort in a place where I
didn't originally lay a "dedicated" zone cable.

It therefore seems to me to be the next logical step to use a CAT5
patchpanel for the Comfort zone connections to make this process as
straightforward as possible, - nothing more than completely standard CAT5
crimps / patches required to connect anything, anywhere...

Slightly confused here Paul



Why put the Zones through a Patch panel

Not the type of thing you need to change very often

If you are trying to tidy the wiring just use Krone blocks

Hint

You can also use the earth/common blocks for  12v 0v KB KA as well

Hoping someone can recommend a CAT5 patchpanel... - This is for my
Comfort zone connections... - I'm looking for either a 32port 2U model
(I have found a couple of suitable candidates of these), or, - and
perhaps preferably, a 48-port 2U panel, - but with the ports grouped in
blocks of 8 - all the ones I've seen so far have them grouped in blocks
of 6... - there are *loads* to choose from blocked in 6, but thus far I
haven't found a single one grouped in blocks of 8... - I'd prefer blocks
of 8 purely for aesthetic purposes, since all the Comfort connections
are grouped in 8's (16 input zones, 16 output zones, up to 8 keypads,
etc...) - so it would be a good fit to the comfort cabling scheme to
have logical blocks of 8 ports...  -  makes identifying areas simpler in
my mind...



My other option is to use a 32-port panel, - top row of 16 for inputs,
bottom row of 16 for outputs, and then not put the
keypads/doorstations/UCM's etc via this panel. But wire those straight
to the comfort board instead... - Given that keypads & doorstations
require shielded cable, this might be a good idea anyway....



However, given that 48-port panels are no more expensive, (and very
often cheaper) than a 32-port, it seems a bit mad to just get a 32....



I've looked in all the usual online suppliers...



Cheers.
