There’s no uniform color-coding for doorbell wires. Add a second chime cable at the transformer, exactly like the cable to the existing chime. Your existing transformer may not be powerful enough to handle both chimes. So if you get a weak sound, replace the transformer with a 15-20VA (volt amp) unit.

What voltages are doorbells?

Doorbells operate on very low voltage. Older models typically require just 8 to 20 volts of electricity — most often 16 volts — while newer models take 24 volts of electricity. Newer models have higher voltage output to accommodate longer runs of wire in larger homes.

What size transformer do I need for two doorbells?

Single door chimes work best with 16-volt, 10-watt transformers. To power your additional chime(s), you will need to install a 16-volt, 30-watt transformer. The voltage and wattage of transformers is stamped or printed on the body of the unit. The 30-watt transformer can be located almost anywhere in the house.

Can I use 2 ring doorbells together?

A home can have multiple Ring video doorbells, all functioning simultaneously. Each device can be given a unique name and ring sound in the Ring app so that the user knows which door a visitor is at. If you have a large home with multiple exterior doors, this feature works great.

How are two doorbells wired?

How many volts do I need for a Ring doorbell transformer?



16-24 VAC

Both Ring Video Doorbell Pro and Ring Video Doorbell Pro 2 require a doorbell transformer rated at 16-24 VAC 50 or 60 HZ, 10-40 VA. Troubleshooting will be the same for both doorbells but if you want to see which version of Video Doorbell Pro you have, you can look it up in the Ring app.

What voltage is wired doorbell?

8-24VAC
