ᐅ Electric gate opener, doorbell, and release all on a single cable

Hey,

I hope you can help me solve my problem. Maybe it’s quite simple...

I have an electrical cable under the paving in the driveway that was originally intended for an electric gate. If you use a double-leaf gate, both leaves need to be powered. So, I assume you can run the existing cable to the first gate post, then branch it off to the second post. I hope my thinking is correct so far?

Now it gets a bit more complicated. If there is a doorbell on the gate, it also needs power. I got a Ring Doorbell Pro, which – as I found out – can be powered continuously via a power supply instead of having to replace the battery whenever needed. The idea would be to tap into that same cable to provide continuous power to the Ring, and inside the house there would be a chime that rings when someone is at the gate.

I noticed that many gate openers operate on 24V, which is also what the Ring requires, as it comes with a transformer for the electrical panel (distribution board). So if you connect the Ring to the gate opener, you wouldn’t need to install the transformer in the electrical panel. Additionally, I’m thinking about installing an electric door strike for the gate’s pedestrian door that could be triggered wirelessly to open it remotely from the house...

Maybe you have other suggestions?

Thanks in advance!

How many conductors does the cable have?

That’s a good question... If you ask like that, I think a 5-core cable is probably better, right?

Yes, with that you could basically supply three separate consumers.

However, when purchasing a double-leaf system, you need to make sure that each leaf requires only 3 wires for control: phase, neutral, and ground conductor if needed. In my case, there are 4 connections per side because each direction (open and close) requires a separate phase.

Um... I’m completely lost here...

Or rather, I need to buy a system that is designed for a maximum of 3 cables per side (panel), while you have one designed for 4 cables. Is it correct that with a maximum of 3 cables, this will work with the probably existing 5-core cable, allowing me to supply the other consumers with the same 5-core cable? Is that right?
