- SkyBell must have full-time power and be connected to a wired, analog doorbell chime.
- SkyBell can only connect to low-voltage power from 10-36 VAC and 12 VDC with an amp range of 0.5 to 1.0.
- Do NOT connect SkyBell to 2 terminals of a transformer without a 10 ohm / 10 watt resistor on one connection.
If you are using SkyBell (1) without a doorbell chime and/or (2) with VDC power, you MUST use a 10 ohm/10 watt resistor for one connection between SkyBell and power source. Resistor not included in packaging.
