I live in the UK and have a traditional 12V hardwired doorbell chime wired up to a Jeani JBT012 transformer (4-8-12V 50/60Hz 1A).
I’m thinking of buying a Ring Video Doorbell Pro 2, which requires a 16-24 VAC, 10-40 VA, 50/60Hz transformer. If I replaced my incompatible transformer with the 24V DC, 0.42A, 10W DIN rail transformer (supplied with the RVD Pro 2 – UK version), I would have to bypass my 12V hardwired chime and use a wireless chime instead.
I would like to use a traditional hardwired chime rather than a wireless chime. Seen as I cannot find a 24V chime, presumably a RVD Pro 2 would operate correctly with a compatible 16V transformer and 16V hardwired doorbell chime?
If yes, then…
- Would the Honeywell D117 Home Ding Dong Classic chime be compatible? PDF suggests it’s 16V compatible.
- Can anyone recommend a transformer that will be compatible with a RVD Pro 2 and a 16V doorbell chime?
- Would the Protek BT8-16 Bell Transformer (16V, 8 VA, 50/60Hz) be compatible? Despite an 8 VA rating being outside Ring’s 10-40 VA range, I’ve seen people on the internet say it works with Ring’s doorbells, but also some say they don’t!
Also, despite Ring specifying a 10-40 VA transformer is compatible, I’ve read 30 VA is recommended. So, what are the pros/cons of 10 VA compared to 30 VA?
