Hi,
I'm flooding our renovation with cat6.
Is cat6 good for connecting my detectors/sensors/keypads etc... to Comfort?
thanks!

If your using one type of cable make sure its shielded so your voice works A ok!

Just be careful when terminating the cables if they are single core instead of multistranded as it is easy to nick or break the wires. I think CAT6 multistranded is also available which is more flexible and does not break so easily

Currently flooding my new house with cat6 for data.
But still using cat5e for the the alarm panels keypads and alarm cable for the sensors as it is so much easier to work with and is cheaper.
Have you tried to get cat6 into a PIR?

Any of the above will do - the CAT6 is more bulky and total overkill.
As already mentioned always use screened for voice /mic.
We have installed hundreds of Comfort panels and always used to use CAT5. However rarely if ever did the other cores get used so we now simply install alarm cable which is actually so much easier to 'pull'. Also when terminating the cables at the comfort unit using alarm cable means that you can make an even neater installation.
Of course alarm cable is available in white or brown 4, 6, 8,or 12 core and is significantly more cost effective.

Do you mean to say you use Alarm cable for security sensors and shelded CAT5 for keypads?

To add to the last post - you can also purchase shielded 4,6,8,12 core alarm cable in white or brown.
So in response to ident we now use alarm cable for most applications.

Ok but be careful when you use alarm cable for keypads, UCMs etc for long distances
The RS485 Comfort bus achieves longer distance for twisted pair but alarm cable is not twisted

So if I have sensors that require a long distance cable di I use stranded cat5?

Stranded CAT5 is easier to handle than solid core CAT5 for alarm sensors. generally there is no problem with distance for alarm cables as long as the cable resistance in tens of ohms

We cannot define what is long
The RS485 standard specifies twisted cable, to prevent noise interference. It does not say how much the performance would be degraded by if nontwisted cable is used
It depends on many factors like distance from interfering signals like mains cables etc so it cannot be guaranteed. If your alarm cable is shielded that does improve the situation, so you wil have to make a judgement based on experience
