Newhouse Hardware Hardwired Chime Kit with 16-Volt/30VA Transformer and Surface-Mount White Button

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.

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.

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.

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

This chime box overheats quickly and easily and could lead to potential fire hazard. I bought it to use with my 2nd gen Google Doorbell and initially gave the chime box 24v which was heating up and making buzzing sound non-stop then I tried lowering the power to 16v but same issue. DO NOT BUY this chime!

Tonally flat. Cheap looking case. Had an issue with doorbell pushbutton sticking in - which started the doorbell unit smoking from being permanently activated.Removed after this incident.

Arrived broken. Received full refund after a couple of weeks.
