UK Can I use CAME dir 10 photocells with generic pair and 909 control panel?

[Charlieh20]

I’m installing a driveway gate and need two sets of photocells in series to stop gates when car is in the way of either pair. The set that came with the kit are straight forward, both units have a + and -. The receiver has the contact that’s closed when there is nothing in the way. Another pair the same would be easy to wire in series. But the 2nd pair are CAME dir10. The wiring diagram is different, it has a link labelled tx which joins the transmitter to receiver and doesn’t go to the board. The wiring diagram is different, are they compatible with the kit? The first pair only has 4 terminals on the receiver and no tx link as shown.
