How to Connect an AC Power Supply to Your Swann Security Doorbell
You can connect compatible Swann Security Doorbells to an existing 12 to 24VAC power supply for continuous charging, so you won't need to recharge the battery manually as often. This guide explains the basic requirements, what to expect during installation, and important safety tips before you begin.
Things to Know
Before connecting your doorbell to AC power, make sure you have:
- A compatible Swann Security Doorbell (model numbers are listed above)
- An existing 12 to 24VAC doorbell transformer (up to 0.5A)
- A voltmeter to verify the voltage
- The included mounting accessories and wire connectors
- A small Phillips screwdriver
WARNING! If you're unsure about working with household wiring, contact a licensed electrician.
How to Install
Short answer: Connect the two AC wires from your 12 to 24VAC power source to the two terminals on the back of the doorbell. Since it uses AC power, either wire can be connected to either terminal because polarity does not matter.
- Use a voltmeter to ensure that the standard powerline has 12 to 24VAC
- Loosen both terminals on the rear of the unit
- Secure the included wire connectors to the terminals
- Remove the pre-cut insulation from the wire
Secure the wires to your existing 12 to 24VAC (up to 0.5A) power using the included wire nuts
- Align the slot of the rear of the doorbell with the bracket and then slide it down into place
- Tighten the anti-tamper screw with a small Philip screwdriver
- Once powered, the Swann Security app will show the battery as Charging until it reaches Full Charge.
Why It Matters
Using an AC power connection keeps your video doorbell's battery charged automatically while maintaining normal operation. If household power is interrupted, the doorbell will continue running from its built-in battery, helping keep your home protected.
Related Scenarios or Questions
Does AC wiring have positive and negative terminals?
No. AC wiring has no polarity, so either wire can connect to either terminal.
Will the battery still be used?
Yes. AC power charges the battery, and the battery automatically powers the doorbell during a power outage.
Can I use a different voltage?
No. Use only a 12 to 24VAC power source that meets the recommended specifications.
I'm not comfortable installing electrical wiring.
For safety, have a licensed electrician complete the installation.
What happens to the battery while powered on AC?
It will charge until full, and uses the battery when there's no power.
Summary
Connecting your Swann Security Doorbell to a compatible 12 to 24VAC power supply provides continuous battery charging and reduces the need for manual recharging.
