Thanks for the info but I am a bit worried that the gates will not auto close, this is something I would need, I bought the photocells as I could not see the old type ones on the website that came originally with only two wires. Is it possible to get them or is there another type that will work like the original? can you give me a link to them on the website? Fancy a trade in on the ones I bought?

As well as being powered, you need to wire the relay output on the photocells into the control panels photocell input. So in terms of wiring, you will need the 24V connection to power the cells and then you will need to wire from the NC and COM contacts on the photocell, into the CLOSE & COM contacts on the control panel. You will also need to do your search for the cells once connected with Dip switch 5 in the off position. Please note, that if using relay photocells on the CB11, the gates will not auto close. This is due to the board utilizing a fail safe type connection, and does not have the 'Photo Test' facility that other boards use.
Hope this helps! Let me know if you need any more info!

I have replaced the normal photocells that come with the liftmaster openers and the cb11 control with the above photocells. The original photocells had only two wires so there was no problem wiring them up but the new ones have 5 and 3. I just wired the +/- to the cb11 as before but they do not work. They do click when you walk through them but this does not stop the gate from closing like before. The gates will open and close ok but the photocells are not doing their job. Does some of the other of the 5 connections need to be made and if so where are they connected on the cb11. If they are wired ok is there anything else that could be the problem?, I have done the learn photocells detail on the controller but it dosen't seem to help.
Thanks for any help
