Came gates

[JoeF]

Hi all, help needed.
I have a set of came ati gates, pcb za3 and until a few months ago  were working fine. I had a problem with them not closing, this was resolved by removing the wiring  from the photocells, intercom and push button in the house, and connecting terminals 2 and c1. Just recently I had a local company quote me £500 to reconnect the photo cells, intercom and push button which seems extremely expensive. The guy said some of wiring needed replacing.
I'm an electrician by trade, but just need help in knowing how the wiring goes for reconnecting the external components on the terminal block.
Also the dip switches, not sure wether they were changed when the original problem occured. So would like to know which ones need to be on or off.
Thanks in advance Martin
Ps. The intercom is a videx gsm 4000 series

Hi,

what brand of photocells do you have are they hard wired or battery photocells?
