Switching of suspended dimmable led fittings

Paul Fay · May 22, 2019

Hi,
I am installing 12 x suspended LED fittings in an office. They are on two switches. The fitting itself comes with a 5 core cable. How do I switch this. Do I need on/off and momentary switch or something else. See attached pic. Any ideas gratefully accepted.

it seems to have a low voltage supply as well as a 240v supply

Looks to be Dali or similar.

thats the dimming control lines 0-10V very common, just look for products under 0-10V dimming

as above.you will need a 5 core cable to the switch, which will be on/off with a variable 0V -10V output.

Thanks for quick replies.I thought as much , I wired the lights with 3 core cable plus a cat 6 for the dimming control. My problem is that the switches for the lights are on a grid. In the past when I’ve dimmed fluorescents before I’ve had a permanent feed and neutral to fittings and a momentary switch for the dimming control. This doesn’t appear to work on my dimmable LEDS . Does each switched run need two switches, an on off then a separate 1-10v dimmer. I have a 4 gang grid switch and was hoping to just use up two places.
