New Video – Deta Doorbell to Ring Doorbell Pro – UK Wiring Guide

Hey everyone, I’ve just published a new YouTube video covering how to switch from a Deta mains-voltage doorbell to a Ring Doorbell Pro (I had the Deta C3051, but the instructions are similar – if not the same – for some similar Deta models):

Hey YouTube, it’s Tristan from Smart Home Point here.

I bought a Ring Doorbell Pro a couple of months ago and then I started looking at how to wire it up. I have a Deta doorbell which is a mains voltage doorbell and I got a bit confused about ‘bypass your internal doorbell’, and one or two other installation instructions, and to be honest I put the box to one side and I forgot about it for a couple of months. But I then spent the past fortnight having a look… or the past week… having a look at exactly how you install and wire up the Ring transformer, what you do about your old Deta doorbell and I’m now a lot more confident to actually install my Ring Doorbell Pro. So I wanted to shoot this video and walk you through exactly what you gotta do step by step to actually convert from a Deta doorbell into your Ring Doorbell Pro. Let’s take a look.

Okay, so in the consumer unit. in this particular house I’ve actually got a ‘Bell’, you can see there, but also the doorbell might be powered off the ground floor lighting circuit instead. Whichever one it is, turn it off and now we go over to the doorbell itself. I’ve already loosened the cover, so I’ll take that off and obviously the power should be off. I’ll just double-check that with a quick voltage test pen. Yeah that’s definitely off. Okay. Right, so what we’ve got here is her a Deta C3501 doorbell and basically this cable down here – that’s coming in – it’s a gray mains cable and that’s the input. And then this cable here is the output cable going to the doorbell and handling any doorbell presses. It’s actually CAT5e cable, most of the strands aren’t used… or half of the strands aren’t used. The blue and white are, as are the orange and white one. They go in to there, so essentially the input earth isn’t used obviously, but the live and neutral is on the input. And then this is the output. So now let’s have a look at what I plan on doing to change this to the Ring Doorbell Pro transformer.

Okay, the first thing to note is that the Ring transformer is designed to go into the consumer unit to attach to the DIN rail in the consumer unit. However obviously I’ve got a mains voltage cable coming in from the consumer unit into the Deta doorbell transformer – or doorbell unit – on the wall, and as a result of that I don’t really want a mains cable coming in – that would essentially be the output here – to go into my Ring Doorbell, which I don’t really want. So what I’m gonna be doing instead is stripping back the Deta doorbell completely, I’ll take that off the wall, so I’ll be left with an input cable coming in and the CAT5E cable coming out. I’ll be replacing it with this, which is a Wylex ESE2 enclosure, in there it has a DIN rail enclosure, so the… the Ring transformer – once I’ve wired it up – will literally clip on to the enclosure, and then it’ll look quite neat on the wall. You’ll be able to see exactly what this is doing because it says Ring and it’ll look quite neat. And this is sort of the correct way of doing it in essence.

In terms of the wiring, what I’m gonna be doing… put that to one side for now… So the bottom “5” and “6” is where the input voltage comes in, and it actually says ‘input voltage’ in there 220 to 240 volts AC current. So this is where – you know – the cables, the input cables, that you’ve seen on the bottom left. They’ll be coming into here, and then the output cables need to go into “1” and “4”, which is explained in the Ring instructions. So the output cables will be coming out of “1” and “4”, and what I could do is just put “1” and “4” going straight into the Ring doorbell here and here, and it will actually work. However one caveat of that is that you’ve got in the ‘Installation Hardware’, you’ve got this ‘Doorbell Bypass Kit’.

Now if you actually take off the sticker – not that you should really have to… this should be made clear from the instructions – but if you take off the sticker, you actually see this says the ‘Ring Pro Power Kit Version 2’. And if you do some Googling what you actually find out is that this is a circuit breaker, it has a self resetting fuse, so essentially what you should do – and Ring’s own support pages confirm this (even though it’s not in the installation guide), but what you should do is one of these input cable… the output cable sorry… so either “1” or “4” should come into here and then carry on into your Ring Doorbell Pro – over there sorry. So in essence you’ve got two input cables – live and a neutral – coming in to the positions “5” and “6”. You’ve then got an output cable – let’s say number “4” – go in directly to one of the terminals on your Ring Doorbell Pro, while the other output cable number “1” – which is that one – will be coming into the Ring Pro Power Kit, it’ll then be coming back out to there on to the other Ring Doorbell Pro terminal, and that actually then completes the circuit. It keep… it introduces… this Pro Power Kit Version 2, which is the circuit breaker, it’s gotta self resetting fuse, so what that means is if anything goes wrong with this – if there’s a short or maybe if you accidentally say that it’s got a manual doorbell and it doesn’t (and that causes a short, or someone simply collects the power button or the push button – then this will… the fuse in this… will flick in your consumer unit. Obviously the bell or the downstairs lighting circuit will flick off, and then you just need to flick it back on and your Ring Doorbell is protected. So without this device – which comes in the Ring installation hardware blue box – without this device it will work, you know it follows the wiring instructions, but you know this is just an added safety feature. It’s a circuit breaker, and it’s worth in my opinion having.

So just to recap, I’ll have input cables coming in here – in terms of wiring it up – my number “4” output cable will go directly to this terminal, number “1” output cable will come into and out of the Ring Pro Power Kit, and then it will go to this screw on the Ring Doorbell Pro. So I’m gonna do that now. I’ll film… I won’t film every single step… I’ll film at the key stages. Let’s see how this goes!

So I have removed the old Deta doorbell, you can see it here. It’s just completely removed from the wall and then up on the wall itself you can see the two cables. This is the output cable – the CAT5E cable – and this is the supply input cable (the mains voltage one). That’s now with the Wylex enclosure, you can actually see it’s been attached to the wall and you can see the two cables – the input on the bottom and the output on the top. What I did here was for the output cabling I butchered an old CAT5E cable, just to get some the blue twisted pair so you can see that that’s coming into the Pro Power Kit. This was a lot easier than actually – you know – splicing the cable in-situ. So it’ll go into position “1” in the transformer and then I’ll connect the existing cable into this Pro Power Kit here. Okay, so that’s the final cabling now in the Wylex box. As you can see here on the left – at the bottom – you’ve got your input supply cable, you’ve got your earth just safely in a terminal, then you’ve got your live and neutral, they’re coming in at the bottom. And then at the top you’ve got your two output cables: your two twisted pairs with the one in position “1” going into the Pro Power Kit as discussed earlier. Okay so that’s how it looks, with the actual case on you can see it says Ring, you know what the device is doing. Obviously I’ll need to do a bit filling work, that’s easy enough.

Now let’s look at the outside. Okay so that’s the existing doorbell with the cover removed, so what I’ll do is just strip that off completely and that’s done now. You can see the two cables coming in, so they’ll just be coming into the terminals on the back, which you can see there the Ring Doorbell’s actually been attached loosely there. So now I just need to turn the power back on in the consumer unit, and you’ll see it goes into setup mode and then I can actually switch over to the app to set up. And that’s it really! You go into the Ring app then and setup and it’s quite easy to do, and then before you know it we’ll be online and you can actually look at your front door.
