Hi,
Went about doing a bit of an internal clean up of the wiring in my main panel over the last few days, mainly cos i started to add a new sensor, and got annoyed at myself for not doing a tidier job of my internal panel wiring.
The messy bit i think is where a panel has multiple items requiring 12v power and coms cable, mine for example has 15 pirs (13 existing and 2 more to go), two keypads and 4 scs\'s, which adds up to a lot of 12v wiring and ka/kb connections.
I did use some connecting blocks to common a lot of it up, but still a bit messy, so was wondering what solutions were available to do this in a more formal manner, or if anyone had any tips, or photos of their panels to show as an example. Needless to say, I\'m not overly happy with mine, its okay, but could be better.

I am reinstalling my comfort after moving house.
All inputs and output connections are terminated off onto krone strips in a 520 cabinet that is next to the comfort panel power for the PIR\'s is fed to a couple of krone strips one for positive and one for negative.
Also have a ADM02 module in the 520 cabinet for connecting keypads etc
Will get some photo\'s when i have got it looking something like.
I am using krone blocks, but just for my velbus. On my comfort 1 system I had used krone blocks for all my comfort wiring, but prob with this is it is external to the panel and not protected, so does not meet standards unless you put it in an enclosure.
Krone is definately a neat solution though, was trying to see if I could fit a single krone block within the panel which would have been neat, but just couldnt wangle it!
Quote:The cabinet is a lockable metal cabinet that will be wired to the tamper circuit of the main panel.
Labels look good, a lot better than my effort.
Cool, would be interested to see it when you have it done uf you can post some pictures. I have a spare comfort enclosure, might see if i can place that next to my main one and mount some krone in it!
On the labels, if you download it as excel, it should be proper dimensions when you print it off!
The cabling in my Comfort panel is getting a bit out of hand and I\'ve also thought of installing a separate Krone enclosure.
One of the reasons my wiring is messy is that I have lots of unterminated cables (e.g there are 6 spare pairs from each PIR sensor attached by an 8 pair cable).
I keep the spare pairs just in case they are needed in the future! Do you chop them off or keep them? How do you guys manage the spare pairs?
Firstly plan the inuts out puts UCM\'s etc and don not over crowd the enclosure.
MAKE SURE mains feeds are away from alarm cables etc.
If you plan the layout start with MDC\'s or contact that have no power. Strip back the cables to the same length and tie back the spare cables - the cables to Z1 Z2 cable tie and before cutting to length loop around your finger -when the terminal strip goes onto the board use the loop as a spare length of cable so that the terminal black can be removed without disturbing the loom should the need arise.
If you can then move onto powered sensors such as PIR\'s ideally if you have an LEM then wire these into the LEM the power cables should be separated and bought out to a terminal strip. If you label them in pairs then they can easily be removed for diagnostics should there be a fault.
Group keypad cables together - group doorphone cables together.
The really messy one is always going to be the bell box cable.
Make sure that you can run the cables in a loom and ideally use a slotted cable trunking so that you can make a really neat job.
Don\'t be tempted to keep adding to the same enclosure - ideally use a separate enclosure for multiple UCM\'s etc.
Also I have provided Cytech with wiring colour code charts in the past.
Cut the outer cable back to the same point for each cable
get a cable tie base and cable tie them all together about 10mm back
twist the cables together in the order of your coulour code
i.e. red and black, blue/yellow, green/white
the attached picture will give you the idea.
I wouldn\'t recommend Krone Strips for alarm cable they are designed for solid cable and can cause false alarms with stranded alarm cable as the connections can come loose over time
