PROTEK Bell Transformer 16V for Smart Video Door Bell Enclosure Wall Mounted 2 Module (BT8-16 16V Transformer) Smart Home

Product Information

For the transformer to fit in the chime case, I had to get rid of the plug-in plastic box it came in. This needs to be done with care, to avoid damaging the internal bits you will use.

The Ring Doorbell Pro requires a constant power supply with a voltage between 16V-24V and at least 30VA of amperage. Our smart home pros have found that in the midwest only about 20% of homes built before 1995 have enough voltage to supply a Ring Doorbell Pro.What this means is that to get enough power for your Ring Doorbell Pro you might need to upgrade your existing transformer. Most older homes only have 10V transformers which don't provide enough voltage for the Ring Doorbell Pro and will not allow for your Ring Pro Doorbell to function properly. What does a doorbell transformer look like? How do I know my transformer has enough power for Ring Pro Doorbell? Where can I find my doorbell transformer? Note on the first photo that the transformer output cables run upwards one on each side of the transformer.Cut the mains power, and replace your previous chime with this one. Connect it to mains using the other end of the cable connectors (brown wire to brown wire and blue wire to blue wire). A dremmel tool with a small cutting disk - ALTERNATIVE: you could also use a stanley knife(harder work) Here are some common problems that indicate your transformer is underpowered. These examples presume you've tested the wiring with a multimeter and confirmed that there isn't a dead wire or short in the system.

If it works normally (ding dong), you are ready to install your Nest Hello. Follow the instructions on the Nest Hello app (not the ones in the video), selecting the version for a 2 wire connection. The transformer divides the incoming AC line voltage into more manageable 16V streams that can power numerous devices at once. Leave underpowered doorbells in the past, and upgrade your current (and failing) transformers. Some small wire connectors (see photos) - the ones I got came on a strip of 12. I only used 3, as I soldered together some of the wire joints (more compact than connectors)

How Do Doorbell Transformers Work?

Doorbell transformer output varies by the home's age and where in the world you are, but typically they output anywhere from 8-24V to 10-40VA, with the most common transformer type in the U.S. being 16V 10VA. That means the transformer steps down the AC power of the home's electrical system into a 16-volt AC output with a "power" of 10 volt-amperes. Try using the Arlo Secure App to install your Arlo doorbell to see if it works with your doorbell transformer. If you find more than 1 set of wires attached to multiple screw terminals, wrap each set with electrical tape so you don’t mix 1 set up with another.
