Use of UTP 5e twisted pair cable for 12V touch switches in the Ropam EXP-LIGHT16-RN system

Hello,
I am in the process of carrying out an electrical installation in my house. I am bothered by this problem, namely. The control of the whole house will be with a Ropam lighting controller EXP-LIGHT16-RN. Switching the lights using bell switches, with UTP 5e twisted pair cabling. Will I want to have touch switches powered by 12V, I can supply voltage via twisted pair, I will have 3 pairs of 0.5mm free. The maximum cable length to the switchboard is 25m.

regards

A voltage of 12V for the twisted pair is as acceptable as possible. If it will only be a switching control then I don't see a problem.

Hi, I have a question, what 12V bell switches did you use? I have a client where I am setting up this very lighting controller, but the lady designer has ordered tactile ordinary switches for 24V. I would appreciate a link, regards

The local inputs on the EXP-LIGHT16-RN are controlled by the 230V - N supply and not by 12VDC !
So you need to design the wiring correctly according to the standards.
