FAQ:

Q: What is the best doorbell transformer to buy?

A: Top Rated Best Doorbell Transformers Of 2023. 1 1. Newhouse Hardware 40TR 24-Volt 40vA Wired Door Bell Transformer for Powering Multiple Smart. 1. 2 2. 24 Volt Transformer. 3 3. 24V 40VA Thermostat and Doorbell Transformer. 4 4. Doorbell Transformer. 5 5. 24VAC. More items

Q: What size transformer do I need for two doorbell chimes?

A: My supplier has a small transformer- the size of the standard bell transformer (10v) that is 30 va. This will drive two chimes quite well. And yes, the chimes must be wired in parallel. A 24v trany will probably work, if it is the right va, but it will burn the light out in the doorbell button.

Q: Can I send 16V to doorbell with switch as return?

A: “Also would sending the 16v directly to the doorbell and using the switches as the return to the transformer work as well just flip flop the + and – as I now have them?” That will work also. For low voltage transformer circuit (unlike 120 volt circuits) it does not matter which lead of the transformer the switch is in.

Q: Do doorbells have batteries?

A: Related Articles. Doorbells require electrical power, and that can be provided either by batteries or a transformer converting AC (alternating current) voltage into a much lower DC (direct current) voltage. The DC voltage produced by a transformer is identical to that produced by batteries.
