Setting up a SkyBell with a Mechanical Chime:
Transformer Range: 10-36 VAC 10 VA
Chime: SkyBell works with both digital and mechanical doorbells. Digital doorbells play different
tunes and tend to have speakers. Mechanical doorbells have two plungers and go DING DONG.
The Wired Doorbell Contractor Kit contains both the recommended transformer as well as a
compatible mechanical doorbell. You will not need an adapter if you are using a mechanical
Using a 12 Volt DC power supply with a 10 Ohm / 10 Watt resistor.
Recommended 12 VAC supply:
** This setup requires a 10 ohm / 10 watt resistor. Buy approved resistor.
