Newhouse Hardware CHM1 Door Bell Chime, White

Essential component for fitting the Google Nest second generation wired camera door bell (designed for US home wiring) in the UK. Does the job.

I bought this to use with the Unify Protect G4 Doorbell in the U.K. and it works as expected when following the wiring diagram in the doorbell’s setup instructions. I bought this as it was one of the few that I was able to import it into the U.K. to replace my doorbell chime box, as I preferred to wire this up as per Ubiquiti’s instructions rather than using a relay with my current 6VA U.K. chime box. Attached is a photo of it next to the doorbell transformer the Unify doorbell ships with (on the left in gray). I drilled a hole in the side of the two boxes to allow for the Ubiquiti adapter cables, you’ll also need a short run of cable to complete the circuit, only a few cm. Took about 10 minutes to mount and wire up. The time between the two chimes is a little slower than I expected which could be a power related issue but it’s less than a second, the bell can be clearly heard throughout the house which is its function. It has a satisfying “ding-dong” noise that’s to be expected from a mechanical chime. For anyone looking to fit a mechanical chime to their Unify Protect G4 Doorbell in Europe, using the included transformer and adapters included within the doorbell’s box, then this is what you’re looking for.

Yo, this thing started working right away. I hooked it up to a 16V transformer, which is what the Ring Video Doorbell Pro says is good enough. I tried a bunch of other UK doorbells, but this is the only one that didn't make any buzzing noises. And the transformer doesn't get as hot. Only downside is that it's a bit too quiet.

This doorbell works great with 18v 500ma doorbell transformer (search B0BC7PLLRG) and Eufy E340 wireless video door chime. A reed switch placed near to the solenoid and connected to where the button would normally be on a Byron BY32 allowed me to have my old Byron chimes also working all over the house, although supposedly it could also connect direct to the chime I didn't try that (having had enough trouble before with that).

A simple easy replacement for an old chime that still integrates well with a smart doorbell.

The chime is melodic and loud enough to hear when in another room.

Didnt work as a replacement for old door chime so resorted to the Alexa/RING/Chime door bell

If I had read previous reviews from UK, I would not be writing a review, as would not have stupidly purchased this item. Does not work with the transformer stated as "essential" if you are in the UK as product is 120V not 220V that we have in UK. Wires in transformer are black, white and green, with no information on which is live, neutral or earth. Enquiry I made directly to manufacturer for transformer received a very rapid reply (same day in fact), surprised this item is sold in the UK. Seller must have considerable stock in UK and will take payment for an item that will not work here, and has not described the item clearly to highlight this flaw. I certainly wasted my money
