Power

Power Specifications

A SkyBell uses a low-voltage transformer, that must put out between 10 and 36 Volts of Alternating Current, or AC. We recommend between 16 and 24 volts, as we test our SkyBell units using this range of power. If your transformer is putting out 10-12 volts, then it's probably nearing the end of its life, as transformers output voltage decreases over time. Most homes that were built in the last 15 years should have a transformer outputting enough power for SkyBell devices.

Once connected to power, the SkyBell device will need a short period of time to charge its internal battery before it is ready to sync and use. The duration will vary depending on the power setup being used, voltage and your SkyBell model.

Wiring the SkyBell with a Mechanical Chime

SkyBell works with both Mechanical and Digital chimes. Mechanical chimes have two plungers and go DING DONG. Digital chimes play different tunes and tend to have speakers. See the next section for installation when using a Digital chime.

The SkyBell requires 10-36 VAC (volts alternating current) 10 VA (volts ampere) and 0.5-1 amp (ampere) in order to operate. Most homes that were built within the past 15 years will have a transformer capable of outputting enough power for SkyBell. The Wired Doorbell Contractor Kit contains both the recommended transformer as well as a compatible Mechanical chime.

The diagram below shows how the SkyBell replaces the existing push-button doorbell switch by connecting to the existing doorbell system wires:

Wiring the SkyBell with a Digital Chime

The SkyBell Digital Doorbell Adapter (“DDA”) is required for a SkyBell Wi-Fi Video Doorbell device when connected to an indoor digital doorbell chime system. The SkyBell DDA enables users to remotely control the indoor digital doorbell chime through use of the SkyBell mobile app, (Android or Apple iOS). Users may use the mobile app to turn-off, or turn-on the chime whenever it is convenient – like a ‘Do Not Disturb’ type function. When the indoor chime is turned off, users will continue to receive call notifications sent to their mobile device, but the chime will not ring inside the home.

Installation

The SkyBell DDA installs inside of an indoor digital doorbell chime by connecting the wires to the terminals used for FRONT (representing the front door bell) and TRANS or TRANSFORMER, used for regulating low-voltage power of wired indoor digital chime systems.

  • Insert one wire each into the connector on the SkyBell DDA as shown in the diagram.
  • Ensure the wire is inserted all the way and is not loose.
  • Connect one wire lead to the “FRONT” terminal of the digital doorbell chime.
  • Connect the second wire lead to the “TRANS” or TRANSFORMER” terminal.
  • Make sure all wires are securely fastened.

The diagram below shows how the SkyBell DDA connects to the terminals inside of a digital doorbell chime, which is connected to both the SkyBell Wi-Fi Video Doorbell and the transformer.

Wiring the SkyBell without a Chime

If you are not using a doorbell chime, you must use a 10 ohm / 10 watt resistor on one of the connections between SkyBell and the transformer.

This setup requires a 10 ohm / 10 watt resistor. An approved resistor can be purchase here.

Troubleshooting Power Issues

Power with Indoor Chime

Using an indoor chime:

  • If the SkyBell does not light up, press firmly against the face of the SkyBell just to the left of the doorbell button.
  • If the SkyBell does not light up, adjust the power prongs on the back of the SkyBell to get better contact to the power screws on the mount.
  • If the SkyBell does not light up, short the power screws using something metallic and verify that the indoor chime rings.

If the chime tests good, then continue on to test power to other devices.

Determine if there is sufficient power to the SkyBell:

  • Locate the transformer that powers the doorbell system (sometimes found in the attic, garage or in the wall behind the chime).
  • Record the transformers output specs (e.g. 16V AC 10VA or 24V AC 20VA)
  • Use a voltmeter to check current voltage on the SkyBell mount.
  • If using a 16V transformer, voltage should read roughly 19V AC, for a 24V transformer, power should read over 28V AC.
  • If minimum power is not available, replacement of the transformer will be required.

Intermittent Power Loss

The unit powers on when the two prongs on the back of the SkyBell device touch the metal screws on the mounting bracket. If the device is not sitting properly on the mount, the device will appear to be dead or have no power. This is because the prongs and screws are no longer making contact. A good test of this condition would be to place your hand on the SkyBell applying some pressure

Taking off the SkyBell and loosening the screws on the mounting bracket about a half to 1 turn allows some slack and stops any warping of the mounting bracket. Please check to ensure the metal contacts on the back of the SkyBell are not pushed in, this will also prevent the device from charging/ powering on. Please gently pull the metal contacts on the back of the SkyBell out a little if you find them pushed in so that the device sits properly on the mount. Lastly, please ensure that the doorbell wires are wrapped and properly tucked in under the power screws.

LED Blinking Red / Blue Continuously

The most common reasons for this to happen are:

  1. The SkyBell device is wired to a digital door chime without using a Digital Doorbell Adapter (DDA).
  2. The transformer powering the doorbell system is not pushing out enough power to consistently charge the SkyBell. This condition can be ruled-out by checking the voltage at the SkyBell location using a voltage meter. If the voltage is less than 10VAC, there is not enough power to charge the SkyBell device and keep it functioning properly. This situation is more likely to occur if the transformer is over 15 years old. For a list of compatible transformers click here.
  3. The SkyBell device may not be wired securely. Check that the SkyBell is wired and connected correctly making sure that all wires in the entire doorbell system circuit are securely fastened.
