Which combo units you talking about dude? Hkc do well with there's but definitely need more than one
That's if customer wants to pay in the first place ........
It's funny you say that.... " for those who are used to me in trade lol"
I was Replying to sw , I normally fit a wireless shock with contact on the opener of the bifold and then a wireless shock on the other end of the bifold with contact disabled when using hkc
What panel are you using ?
Just join crimp , solder and extend cables etc
You could bury them in wall and put a face plate on top after
I would open the plaster up more towards ceiling and fit panel higher up if possible then joins can be inside panel
Do you have a better picture?
Dude
Simple process for you
Swap both keypads round
If keypad one works in position 2 atleast you know for sure to an extent the cable power and coms is good
Then it has to be addressing and programming or the keypad itself
