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

Product Information

Note: We recommend that you turn off the power at the breaker before accessing your transformer. When in doubt, consult a qualified electrician. 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. Next, replace it with the Shenzheny Yelingda Door Transformer. The manufacturer includes a set of screws and a threaded clamp. Depending on your desire, you may set it up vertically or horizontally. Thankfully since doorbells work on such a low voltage, if you need to test, install, or maintain one, you can do so with a low risk of injury. However, when you’re working with electricity, you should always verify the voltage and turn off the electricity to the circuit before proceeding with any work. A doorbell transformer is a device that sends the right amount of electricity to power an electric doorbell. Your doorbell transformer can be anywhere in your house, but it’s commonly found in a few places, as listed below.

From the Friedland range that work with upto 16V~ power input, I chose the Freedland D117 Ding Dong chime by Honeywell (see photo). This can be powered by an external transformer with outputs between 8V and 16V, or by 4 "C" size batteries (so loads of free space in the case to fit a transformer). It has a modern, minimal and simple design, that would suit most homes, and the cover is flat, so maximises inside space. Funny enough, the inside of the chime looks identical to the one shown on the official Nest Hello installation video, so probably a good choice.This transformer plastic casing is welded shut, so I decided to chop it open. I used the Dremmel tool with a slim cutting disk (second photo) and cut through the plastic weld on all 4 corners. I then slipped the medium size flat screwdriver in the gap I just cut and twisted it to split the case open (be gentle). I did this on all 4 sides. We will, of course, give it another shot. The first step is to obtain a suitable resistor that will function in series with a 24V transformer. A simple application of Ohm’s law will assist you in calculating the value of the needed resistance. We also need to know how much electrical power the resistor dissipates. This is determined using the power law, which states that power equals current multiplied by voltage. In our situation, power (measured in watts) is 8V times 0.5 amps, which equals 4 watts.

The only issue that would arise from using a 24v transformer is that some of its components may be damaged by overloading or overheating due to an incorrect installation. How do I know what voltage my doorbell transformer is? A doorbell transformer should have a voltage of 16-24V AC. If the voltage is too high it will burn up and if it’s too low, you won’t get a ring. If you’re wondering if it’s safe to use a 24v transformer on your 16v doorbell, the answer is yes. It will work just fine as long as there are no issues with voltage and polarity. How can you tell if your existing transformer has enough power for the Ring Doorbell Pro? 3. Install your Ring Doorbell Pro and see what happens. All the best in however you decide to fit, but had to tell my story so you have all the details before making your own choice.If you don't want to replace the transformer, and you think you'd prefer a battery powered option, you may want to install a Nest Doorbell (battery) instead. You need a transformer that is rated for 16-24 V AC, 10-40 VA to provide enough power to your doorbell. If you've already installed your doorbell and you see a blinking yellow light on the front, your doorbell isn't receiving enough power. How to find and replace your transformer Doorbell transfers are very simple and sturdy devices, and it's not unreasonable to expect the transformer to last for decades or even, potentially, the entire lifespan of the home. A dremmel tool with a small cutting disk - ALTERNATIVE: you could also use a stanley knife(harder work)

You will need either measure the voltage, visually inspect the transformer for a voltage rating or install the ring doorbell and see what happens. Depending on the combination of chimes and video doorbell hardware you have (or if you want to replace both the front and rear doorbells with video doorbells) you'll likely need a bigger transformer. Doesn't matter if you're installing a Nest doorbell, a Ring doorbell, or even a more DIY-type video doorbell solution like those from Amcrest or similar companies.

Wrapping It Up

There are a few different locations where your transformer might be: near the main electrical panel, inside the doorbell's chime box, the garage, or the attic. You can follow the wiring from your chime to the transformer. A licensed electrician is best prepared to find and replace your transformer and install the doorbell for you. If you don't have a transformer Everybody starts their DIY journey somewhere, and if you're just now contemplating that your doorbell has something called a transformer (and that maybe you need to change it out), you're likely in good company---so don't sweat it.

We’ve listed the best places to look for your doorbell transformer below but also created an entire guide with more specifics on where to look for your doorbell transformer here if you are still having trouble locating your transformer. Top places to look for your existing doorbell transformer: 1. Near Main Electrical Panel 2. Basement 3. Garage 4. Attic 5. Near Furnace or Furnace Room 6. Utility Room 7. Crawl Space How can you tell if your existing transformer has enough power for the Ring Doorbell Pro? If the voltage level is between meets the voltage requirement, you can use the doorbell with your current doorbell transformer. 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? For help hardwiring your wire-free doorbell, visit: How do I hardwire my Arlo Essential Video Doorbell Wire-Free? 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).Existing doorbell transformers are typically found in the basement or near an electrical panel. Sometimes they are in crawl spaces or attics. Usually if your home has a basement they will be located close to the electrical panel if it is also located in a basement.
