User questions & answers

Question:	Bought the 16v 30va transformer, now how do I find a 16v 30va doorbell? Electrician says anything smaller will be fried by the transformer
Answer:	Just buy a 16v doorbell. Amazon sells them. The 30va is amount of power it can deliver. Doorbell will only draw the power it needs. 30va can power multiple doorbells or just one. I got this 30va model to power existing doorbell and a Ring video doorbell unit. Get a new electrician.
Question:	My indoor mechanical Chime is says 10-16 volts ac. Will this transformer be too much power and safe to install
Answer:	very safe. i installed mine in 10 minutes with no problems.
Question:	is there a warranty on this item? I can't find anything about this company
Answer:	Not sure on this item, but a lot of the time this type of electrical item does not have a warranty. It did help our Nest doorbell as it made the ringer stronger and much louder than it was before this was installed.
Question:	I just purchased ring doorbell pro, but my old chime locks and buzzes, will this 30va transformer solve my problem
Answer:	Sorry to say this, from my experience with the doorbell pro, you do need this transformer so that the doorbell bell will work properly. I could not find it in stock anywhere. You will need to buy it online. After that if you want an indoor chime you will have to buy a new one rated at 16v and 30a. It would have been nice to know all of this when I was buying the doorbell pro.

User questions & answers

Question:	The unit states on the device to mount in a metal box only. My current device was in standard wall plastic junction box behind door chime. Work
Answer:	Yes it will. The requirement for a metal box is because the unit throws off a little heat and could, under certain rare circumstances, melt the box. Your doorbell or chimes is highly unlikely to pull enough power to heat the unit enough to do that. Why not install the unit, inspect it after an hour, 4 hours, 12 hours, 24 hours and a week. I’m sure you’ll find no indicia of heat damage. If you’re really concerned, replace the box.
Question:	There are 2 points, labeled "R" and "C", on the transformer where you attach wires with screws. What do "R" and "C" stand for? "Remote" and "Chime
Answer:	Two terminals R and C, they can connect any cable, beacuse this is AC power.
Question:	I have a nest hello, and i have had a problem with power. this product was suggested to me, but, what chime could i use
Answer:	You should be able to use it with any chime that requires 24V power.
Question:	I have bought this transformer, it says it is 24v. i am reading 30v at the doorbell button. anybody know if it will cause a problem with a ring pro
Answer:	24 vac transformers normally put out 28 - 30 volts. Any doorbell transformer that I have ever replaced is a 15 volt output transformer.

User questions & answers

Question:	I have an intercom i replaced with a ring, causing me to have to charge the ring. can i wire this to the intercom and then to the ring
Answer:	I can’t answer to the intercom part as far as wiring but the transformer can probably handle it when it comes to the power requirements.
Question:	Will it work with a digital chime
Answer:	If it need 16 Volts I’d say yes
Question:	how do i know if I need a transformer
Answer:	Your simple push button doorbell will have a transformer somewhere, usually mounted to the side of an electrical junction box or the circuit breaker (or fuse) box, often in the basement. If you are installing a "Ring" doorbell, the system requires 30VA at 16V. You will need to track down your existing transformer and read the specifications, which are usually printed on it. If your transformer output is 30VA or more at 16V, you do not need to replace it. Older systems will have a transformer with only 10VA at 16V which will need to be replaced because it will not have enough power to run the new doorbell.
Question:	Can this transformer be installed in an attic
Answer:	I don’t see why not, as long as the wiring you need is there. Also, make sure to put it in an electrical box.

User questions & answers

Question:	Can i run two thermostats with one C wire transformer
Answer:	You would have to discuss this with the company that makes them. However, the dependency would be the power drawn from each thermostat - if they are the new low energy types it may work. The only problem would be the wiring.
Question:	This becomes an exposed wire that runs to your thermostat
Answer:	The "exposed wire" are leads that you connect to your thermostat, or video doorbell. They're not exposed once you connect them.
Question:	Will this work with the vine 610 thermostat
Answer:	This will work with any thermostat. It simply provides the 24V power needed assuming your tstat wire and doesn’t have the additional wires for 24v power. Most furnaces have the 120/24V transformer, but older homes tstat wire never had enough conductors. Newer homes should. Regardless, yes, this transformer with work.
Question:	Does this work with the ring doorbell
Answer:	If you use this with the Ring 2 be sure to check the instructions on the Ring website (https://support.ring.com/hc/en-us/articles/205180710-How-to-Connect-Your-Ring-Video-Doorbell-Directly-to-a-Low-Voltage-Transformer-Without-a-Pre-existing-Doorbell-) for connecting to a power supply without a doorbell. To keep from damaging the Ring a 25 Ohm resistor needs to be added between the charger and the Ring, mine worked for about a week before the Ring quit accepting the charge. My Ring still works, but won't accept a charge or activate a doorbell.

User questions & answers

Question:	my door bell only rings once if botton is pushed once but if you hold the botton down it will have a couple of rings . is this normal
Answer:	If you push one is going to ring according to the bell. My goes din, don short bell and long bell with the back door switch. Check your bell to see if have different settings
Question:	Is a resistor needed when installing this with the ring
Answer:	The 2nd ring it's already been feed by the 1st one so you should need it.
Question:	Does it hum or make noise
Answer:	Transformers can hum. It shouldn't be "noisy" however.
Question:	Will this work for a 3 bell system? The one I have seems to be weak and the bells are not very loud
Answer:	If all three aren't used at the same time. So, unless this is for a busy "speak easy" or ah-hmm "similar" place, it should work. The key word is should. If the bells aren't very loud you may wish to look at hearing aids.... just kidding. This actually puts out more than 16VAC on my 120VAC supply. Mine reads 22VAC. I have it as part of a test bench for checking 115VAC 400Hz aircraft items. It was considerably less expensive than an accurate AC transformer. see less

User questions & answers

Question:	Where is this transformer manufactured
Answer:	China
Question:	How many chimes can this transformer power
Answer:	I purchased it to power up a single chime
Question:	Does this work with ring doorbell
Answer:	Yes.
Question:	Does it work with Armcrest camera door bell
Answer:	No, it doesn't work. We suggest you to buy this one: https://www.amazon.com/gp/product/B07GND8RMQ
Question:	Will this work on simplsafe video doorbell pro
Answer:	Unknown.
Question:	Will this charge a ring doorbell
Answer:	Yes, so long as the distance isn’t too far (you can calculate the voltage drop if needed). I use this transformer on a Ring Doorbell 2, and I’d estimate the distance between my transformer and doorbell is about 75’.
Question:	Is there a way to secure or lock the adapter to the outlet ? I want to use this for my rental TH and don't want guest to unplug it
Answer:	I just put a lock box over the outlets. The only way a person could unplug it would be to literally cut the cable that goes in and outside of the box. They sell the boxes on Amazon (very cheap) and you can even get metal ones if desired and most are weatherproof if needed. Not sure if this helps, but again, the boxes come with a corner 'hole' that is specifically for a lock. Again, hope this helps you! I'm just a customer too...
Question:	If it's for the Nest hello doorbell, how it works

User questions & answers

Question:	does this include instructions for two chimes
Answer:	I don't remember if it did or not. The instructions were very detailed, but I didn't really follow them. I just swapped it for the old one.
Question:	Is the transformer small enough to be placed within the Ring Video Doorbell
Answer:	no transformer is small enough to fit within the ring doorbell. The wires that feed your existing doorbell go to a transformer that should be located in the upper part of your front door closet. If you don't have a closet, then the transformer probably is contained in the chime box.
Question:	is this compatible with simply safe
Answer:	yes i have this same transformer hooked to my simplie safe
Question:	I purchased it to replace 24v 40va for ring pro. however i see voltage slowly dropping with this too. can you advise
Answer:	I purchased the 24V Xmfr to replace my existing 16V Xfmr. I used the "power booster" that came with my Ring Pro. I'm assuming the power booster serves the same purpose as the resistor.

User questions & answers

Question:	Will this work with SimpliSafe doorbell
Answer:	I believe Simplisafe recommends a 16V transformer so yes it should. This one has a slightly higher 30VA rating vs 'norma' transformers so it is designed to support 1-2 doorbells if you need to connect to same circuit (.e.g. front door only or both back and front door on same chime)
Question:	I don't have an existing doorbell. Wouldn't the transformer need to be mounted into a box since 120v is also coming out at one end
Answer:	Mine is in a box.
Question:	Will this work with an Arlo video doorbell
Answer:	Sorry,it doesn't. The Arlo video doorbell requires a 10va transformer.
Question:	Does it work with Ring doorbell
