How to wire a Ring wired video doorbell

Helpful video reference. The embedded video shows a UK home installation of the Ring Wired Video Doorbell, covering the transformer check, bracket fitting, bell-wire connection and first startup in the Ring app. Watch it end-to-end to get a clear sense of what the job involves before you start. Original video: "Ring Wired Doorbell (UK) — a Step-by-Step Guide to Easy Installation".

1. Check your existing transformer

Find the doorbell transformer — usually mounted inside a hallway cupboard, under the stairs or inside the consumer unit enclosure — and read the label. You need the secondary output voltage: typically 8V, 12V or 16V AC on UK models.

The Ring Video Doorbell Wired (the entry-level wired model) works on 8-24V AC, so most existing transformers are fine. The Ring Video Doorbell Pro, Ring Pro 2 and Ring Wired Plus all need a minimum of 16V AC. If your transformer outputs 8V and you have bought a Pro model, you need a new transformer before you go further.

Test with a multimeter across the secondary terminals with the power on — a reading 10-15% below the label rating is normal under load. A reading of zero suggests a blown transformer or an open-circuit winding.

2. Isolate at the consumer unit before touching the transformer

Even though bell wire is safe at low voltage, the transformer primary is at 230V. Switch off the MCB or fuse that feeds the circuit supplying the transformer and lock it off if your board allows. A lighting circuit often powers a hallway transformer via a spur — check both.

Confirm dead with a voltage tester at the transformer primary terminals before you open the cover. If you cannot identify which circuit feeds the transformer and do not have a tester that can find the live cable, stop here and call an electrician.

3. Remove the old bell push

Unscrew the old push from the door frame. Most are held by one or two small screws. Pull gently and the push should come away with the two bell wires attached.

Undo the terminal screws and remove the wires. The bell wire conductors are usually red and black or figure-of-eight twin with a rib on one side, but polarity does not matter on a standard bell circuit — you can connect either wire to either Ring terminal.

If the wires are corroded at the ends, snip back 30-40 mm and re-strip. Bell wire insulation strips easily with a sharp knife or small strippers.

4. Fit the Ring mounting bracket

Hold the Ring mounting plate at the correct position on the door frame. For most installations the camera faces the visitor head-on. Ring supplies a 15-degree wedge if your frame is angled or if you want to tilt the view — use it if the door does not face the street square-on.

Mark the two fixing holes with a pencil, drill at the right diameter for the supplied rawl plugs and screw the plate down firmly. Feed the bell wire through the central slot in the bracket.

On a uPVC door frame, drill carefully to avoid splitting. On timber, use the screw directly without a plug if the wood is sound.

5. Connect the bell wire

On the back of the Ring unit there are two small terminal screws — one marked with an orange dot, one with a black dot on some models, though most just have two identical screws. Loosen both.

Insert one stripped bell wire conductor into each terminal and tighten firmly. The wire should not pull free when tugged. Polarity does not matter for the Ring Wired or basic Ring Video Doorbell models.

Fold any excess wire back into the hole in the bracket, keeping the conductors clear of the mounting screws.

6. Seat the doorbell and configure the app

Press the Ring unit down onto the bracket until it clicks. Restore power at the consumer unit. The Ring unit should power up within a few seconds — the front LED will flash or glow.

Download the Ring app if you have not already, create an account or sign in and tap the plus (+) to add a new device. Select the model and follow the in-app setup steps: connect to your Wi-Fi network and enter the activation code on the back of the box or inside the Ring unit itself.

If the app shows "hardwire issue" during setup, this almost always means the transformer voltage is too low for the model you have bought. Check the transformer output and upgrade if needed.

7. Test all functions

Press the button and confirm: the chime triggers (either a traditional mechanical chime wired in series, or a Ring Chime plug-in unit), the live view appears in the app within a few seconds, and motion detection triggers when you walk past.

Adjust the motion sensitivity and zones from the device settings in the app. Ring's "motion scheduling" lets you reduce alerts during busy daytime hours and increase sensitivity overnight.

If the traditional chime does not ring after the conversion, check that the wiring from the Ring unit to the chime unit is still connected and that the chime type is correctly set in the Ring app settings.

When to call us

Connecting the bell wire to the Ring unit is usually straightforward for a careful homeowner. If the transformer needs replacing or if there is no existing doorbell wiring, that is the point to get a qualified electrician involved — Richard covers small jobs in Sandwich and east Kent at the £10 per 10-minute local rate.
