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!

No, the cable is simply coiled up beneath or inside the split unit (or even a bit further down) and would need to be pulled forward approximately 5-6 meters (16-20 feet) from its current position to the future gate or driveway.

Edit: What exactly do you mean by more cables? Couldn’t you use a junction box for the other consumers? I would like to keep it as simple and straightforward as possible...

Now it’s too late anyway, but why is it done like this?
Are you sure there is no pipe further down? Any pictures of the installation?
How many conductors does the cable have?
Tap power for the doorbell. If there is enough space in the gate, you can house it there.
Usually, the gate manufacturer provides precise instructions. For the other leaf or photoelectric sensor, a conduit is simply installed and led over from the main side.

Make absolutely sure that there is no pipe below. I think you mean a conduit?

I need to ask my electrician what he installed there....

Here you can see the cable under the ladder, which looks quite thick, and then exits to the left through the PVC pipe.

Renovation room with GROHE flush-mounted cistern in the frame, insulated pipe on the left, ladder on the right.

@11ant A single-leaf folding gate? Sounds interesting, since that would eliminate the need to run cables to the second post, I assume?
Yes, that would then be a passive/dumb stop.

There are also wheel gate operators available. They support gate leaves up to 7m (23 feet) in length and 150kg (330 pounds), and in that case, you only need one. I’m just not sure if you have enough space for such a large gate.
