Will a Ring Doorbell Ring My Existing Chime?

• A 16–24 VAC supply is the minimum for the Wired Doorbell 2K Plus and 4K Pro. Many UK bell transformers give less, so these doorbells run from Ring's 24 V DC DIN Rail Transformer or Plug-In Adapter instead
• A chime left in circuit on that DC supply is at risk; in Ring's words, 'Not bypassing will cause damage to your existing chime'
• The Wired Doorbell 2K and the Video Doorbell Wired come with a bypass cable, so the chime is bridged out rather than removed
• Battery doorbells draw only a trickle from the wiring, so they can share it with a compatible chime

• DETA C3500, C3501 and C3504
• Byron 720, 70217 and 761
• Friedland (Honeywell) D902 'Door Bell-in-One'
• Friedland E821 Quartet, E851 Serenade and CE861 Orchestra
• Grothe CROMA 230, CROMA 231A and CROMA 50
• Kocom videophone

• Choose Mechanical for a chime whose hammer makes a ding-dong, or Digital Type 1 or Type 2 for one that plays electronic tones; battery doorbells also offer Automatic Chime Detection
• Choose None when the doorbell is on the Plug-In Adapter, wired straight to a transformer, or has its chime bypassed
• With more than one wired chime, Ring says to bypass the extra ones by joining the wires on Front and Trans with a wire nut
• Check that 'Ring my in-Home Chime' is switched on in the doorbell's settings

• Confirm the chime type in the app matches the chime on the wall
• Move the doorbell wires clear of the chime's moving parts, which can catch on them
• Check the transformer against the doorbell's range, which Ring lists as a cause
• If the chime is not bypassed, test it by bridging the two doorbell wires

• Chime (3rd Gen): plugs into a socket and connects on 2.4 or 5 GHz Wi-Fi
• Chime Pro (2nd Gen): adds a Wi-Fi extender for Ring devices and a night light
• Chime Plus: a plug-in chime with a night light, on 2.4 GHz Wi-Fi 6
• An Echo or other Alexa speaker linked to the Ring app

• The chime, and its make and model if a label is visible
• The bell push and the door frame around it
• The transformer label, wherever it is
• Which Ring doorbell you have, and whether you want to keep the old chime or move to a plug-in one

A vetted pro prices your Ring job from the model and your photos, and the JACK app shows that fixed price before you book.

Power moves the price more than the model name. A battery doorbell or camera on a wall with a good signal is the lightest job. A wired doorbell brings in the bell transformer: if yours gives 8–12 V AC and the doorbell needs 16–24 VAC, the job includes fitting Ring's 24 V Plug-In Adapter or a transformer on a fused spur, plus bypassing the old chime. A floodlight cam is priced as electrical work on your outside-light circuit, including any change to how it is switched.

The wall and the height come next: solid brick, render, a narrow uPVC frame that needs a wedge or corner kit, or a camera 2.5–3 m up that needs a ladder or a tower. On a high eave, your pro can ask another pro on JACK to help through the Pro2Pro feature. Cable runs through brick or to a PoE switch add time, and so does each extra device, though every device can go on one booking for one fixed price.

You buy the device; JACK does not sell any. Accessories the job needs, such as a transformer, a Ring Chime, a wedge kit or an outdoor junction box, are agreed and added at cost before you book, and so is parking where it has to be paid for. Prefer to pay for time? As a guide, hourly hire is typically £45–£95 per hour for smart home work and £55–£110 per hour for electrical work. For a big multi-device job, say a doorbell, three cameras and an alarm kit, a full-day handyman booking is a flat £350–£400 for up to 8 hours on site.
