Why You Can't Install a Ring Video Door Bell with a NuTone Intercom System or Musical Chime

ring pro power kit necessary

hi in today's video we're going to talk about something that I get or-or five emails the weekly phone calls about and I thought I would cover it in a video what we're looking at here is a ring video doorbell it's one of these Wi-Fi video motion sensing doorbell Internet of Things devices and no this is not going to be a review on ring video doorbell I have a

ring video doorbell on my house and I think it's a quite a fine product and I actually enjoy having it but the thing I get asked about all the time is if I have a new tone intercom system or me have a new tone electronic door chime how do I hook up the ring to the wires that come out of the wall for either my door speaker or my doorbell button

or whatever it is I have out there I've explained it a million times to people and I thought now's a good time to make a video so hey it's kind of hot out here let's go back in the shop where it's nice and cool and talk about ring and intercoms and doorbells and things like that so off we go back to the shop to try to understand the challenges of installing a ring

video doorbell when you have a new tone intercom system with a built-in chime module or a new tone electronic musical chime you have to understand a little bit about a basic doorbell circuit so you can compare this to what you have in your house so what we have here is a representation of the most fundamental doorbell system that would be in probably 85 or 90% of everyone's homes that were built since the 1960s

so here we have a 16 volt transformer that powers the door chime we have a standard two note mechanical door chime here this is your garden-variety ten dollars hardware store special doorbell and here we have a push button on the front porch and then we have the wiring that connects it all together this is wired in a way that would apply to probably 95% of all the houses of anyone watching this video or

what you should understand is the transformer supplies the power the 16 volts to power the doorbell circuit the push button activates the door chime and the door chime is responsible for making your classic Gong sounds as it rings and what you need to consider is how this works and it's actually fairly simple it's all about the flow of electricity so the electricity starts here on the right-hand terminal of the transformer and it travels up the

wire and we're going to put the blue arrows to show the direction that the electricity travels in so it travels down the green water it goes through a splice joint that's usually behind the time it continues down the green wire all the way down to one side of the push button the push button is a mechanical switch so when it's not being pushed the switch is open and the electricity stops right here

on this side of the button when someone walks up and pushes the button down it closes the switch and the electricity flows through we'll put little arrows here and then it flows up the orange wire like this to the chime mechanism which is an electromagnetic solenoid that's built into the center of the chime it energizes the solenoid and the magnetic force that the solenoid creates pulls the plunger down it strikes the bottom tone bar

and it goes ding and when the visitor releases the button the plunger shoots back up because of the spring with on the top of it and it goes dong so while the button is being pushed the electricity travels through the wire through the solenoid and then back down the other orange wire all the way back down to the transformer because electricity is all about flow so the flow just to review briefly the

flow begins on the right-hand side of the transformer it travels up the green wire through the splice joint down to one side of the button if the button is being pushed the electricity crosses through the switch of the push button back up the orange wire it energizes the coil it goes ding and then it continues back to here of course since the electricity moves through the wire at the speed of light it

moves faster than someone pushing the button so it actually completes the circuit immediately when the button is pushed the reason it's important to understand this is if you want to add a ring video doorbell to a system like this you can do that because basically, all you have is electricity flowing through wires which is as I understand it what the ring video doorbell when you connect your video doorbell to the wires that used to

be connected to the back of the button so this is a very simple switching circuit it works very much like when you walk into your living room and you flip the light switch on the wall to turn the table lamp on the light switch is a mechanical switch just like the push button and when you flip the switch in on your living room wall you're making a connection and the electricity flows

through the switch and the lamp next to the sofa turns on it's exactly the same thing this would be very easy to reconfigure slightly in how the wires are being used and power your ring video doorbell from the low voltage transformer all said and done very simple not a big challenge now let's take a look at how your intercom system with a time module or a new tone electronic musical chime varies from this

so here we have a wide array of circuit boards and to just go through them briefly this is a new tone chime module this is an IA 28 and this would be used in any new tone intercom system that was manufactured between 1984 through about 2010 here we have the board out of a new tone lb 55 which is an electronic musical chime this would have been manufactured sometime between 1975 and about

1999 here we have an L BC 55 which is a variation on the LB 55 it has a built-in clock this was same time frame as the LG 55 here we have an L a 60 this would be the mid 80s through mid-2000s chime this is the board out of an LA 52 which is an electronic musical china tone made starting in the 70s and was popular and available all

the way through the early 2000s and this is a circuit board out of a new tone la 174 which is a recess mounted Westminster chime that they still make today while all of these boards are different they all share one common design aspect and that is they all have microprocessors on the boards this is the microprocessor on an in 28 under the flap there is a microprocessor on the LV

55 on the LBC 55 the micro processor would have gone right here in this socket but obviously we've robbed that for some purpose this is the micro processor on the LA 60 this is where the microprocessor on the LA 52 would have been and this is the micro processor on the la 174 the reason that all of these chimes have microprocessors it actually began with the LB 55 which was the

first musical electronic door chime new tone ever made and back in those days they needed a device that would have the ability of operating the time but also would store the songs and notes that you needed to play the songs that were programmed into the chime and back in the mid 70s a microprocessor was the way to do that and there'll be 55 like this would have had between 18 and 24 pre-programmed songs

and they're reasonably long you needed a place to store the information that would allow the time to play the song as it was designed and the microprocessor was the component of choice also the microprocessor has the ability of controlling the operation of the chime so you have a lot of benefits by using one component that can do a lot of different things I've cleared away all the other circuit boards and what we're left with

here is the Newtown IA 28 everything that I have to say about this applies to not only the ia 28 it also applies to the ia 29 which is the musical chime module as well as all of the other board for all of the other models of new tone electronic chimes just easiest to talk about the chime module because that's what most people actually are dealing with so again like the other boards here

we have a microprocessor in the middle of the board everything else on here are supporting components that allow it to work electronically but the microprocessor is the heart of the chyme module just like it's the heart of all the new tone electronic musical chimes so why did new tone decide to use a microprocessor as the heart of all of their electronic musical chimes and chime modules well it's because microprocessors allow you to

install in them a program and the program makes the device the chime module or the electronic musical chime operate the way you choose it to in the case of a chime module and new tone electronic musical chimes they all have as a minimum the ability to ring differently on a front door and a rear door push button and many of them have our three-door capable which means they have front rear and side

door buttons and when you have multiple buttons they each ring differently so the resident of the house knows where the person is it would be more complex to design a device that would have three different rings for three different doors if you didn't use something like a microprocessor it would be much more elaborate much more complicated and therefore probably much more expensive when you have a microprocessor you simply write the program that's loaded into

it to tell it when the front door is activated ring one way when the side door is activated to bring a different way when the rear door is activated ringette a third way and that way it's easy and as you change your devices or update your devices you can change the program and that's a relatively easy thing to do the program is basically like a little tiny bit of software not that much

different than the app you download into your phone although infinitely more simple and so it's an easy thing to make a change to without having to change the entire hardware or in itself part of the program that's loaded into the microprocessor let's call it the management program the program of the microprocessor is going to manage the operation of the chime module and one of the things that it has to do is it has to look

all of the time to see if a button is being pushed or not it can't really look for a button push every 10 seconds or every minute or every five minutes because if someone shows up and pushes the button while it's not looking it's not going to ring so the program in the microprocessor looks for a button push all the time continuously over and over and over again forever as long as there

is power to the device so when a time module is installed in a new tongue intercom master station and the master station is powered up the chime module turns on and the program in the microprocessor starts looking for a button push and when it sees one it's going to ring the chime the appropriate ring for whichever door the button was pushed down so that brings up the next question which is how

does the microprocessor know which button is being pushed because it's mounted way somewhere inside someone's home and it obviously can't see it's not a brain per se it's not smart it only knows as much as the program allows it to know so the way that these kinds of devices are designed the microprocessor sends out a little bit of electricity down the wires to each of the individual buttons and it has as part

of its program the ability to monitor the voltage of the electricity that it sends down to each button and it sees and measures that what that amount is and as long as that amount stays relatively constant it knows that no one has pushed a button one of the byproducts of the little bit of electricity that it sends down the wire to the button is it allows the button to have a little tiny

light bulb built into it so at night when someone walks up to the door you see the glow the bulb and it's easy to find the button and push it when someone comes to the door and pushes the button and since the button is basically a mechanical switch just like we talked about on the whiteboard drawing from for a standard to know doorbell when you push the button it changes the voltage that

is being sent through those wires let's say to the front door button and the microprocessor is program sees the change because in the voltage because the button has been pushed and it recognizes that hey someone's pushed the front door button now I have to ring the chime so immediately following the button push which then created a voltage change on the wires to that button the microprocessor saw that change it looks up in its program

what it's supposed to do and if it's the front door button on an ia 28 it knows that it's supposed to ring the eighth note Westminster chime and that's what it does so it rings the time you hear through the intercom system and when it reaches the end of the of the chime tones it stops it resets and it starts the program over again looking for another button push because if it's the

piece of delivery guy maybe you didn't get to the door fast enough and he's got a lot of deliveries to make so he's going to push it again if he does push it a second time the microprocessor is going to see the change in the voltage on the wires again it's going to look up the information it's going to rainy eight-note Westminister time and then reset and wait again if someone comes to the

back door and pushes the rear door button the voltage is going to change on that line and that brings up the question of how does it know which button is being pushed because if it's electricity out on each set of wires to each button and that it's looking for a change in the electricity how does it know well that's you're actually pretty simple the amount of change in the voltage on the front

door will be different than on the rear door and on the side door the amount of change will be different because that's what all of the supporting components are for some of the components different for each circuit and so when someone pushes the button the way the electricity or the amount is electricity changes is different in the microprocessor because of its program knows to look for certain changes so let's say the front door button

changes by 10 so it knows that it's the front door button but the rear door maybe it changes by 5 and the side door button changes by 2 so if it sees a change of 5 it knows it's not the front and it knows it's not the side it only can be this one because that's the amount it's looking for this is the advantage of having a device like a microprocessor that has

a program with instructions in it because you can tell it precisely what it is to look for and precisely what to do when it happens so now you have sort of a basic understanding of how a chime module or how a new tone electronic musical chime is activated so what this is referred to as it's referred to as a triggering circuit because when you push the button you're triggering the chime module to

look up something in its program to ring the appropriate tones and then reset again so you're triggering it as opposed to it being like a light switch on the wall in your living room when you turn on a table lamp on let's talk about how this defeats the idea of putting a ring video doorbell on the wires on your front porch in place of the push button that's always been there so the

one thing and I get a lot of calls from people about I had a call from a fellow this morning he said I bought a ring video doorbell I have a new tone intercom system he has a chime module how do I hook it up to the wires and I told him the short answer is you can't it won't work and he's like everyone else who calls me about that but-but-but-but and

there is no but but-but-but it's not the same kind of circuit so he said and then he told me well I took the button off and I measured at the little wires that used to be on the back of the button and I measure electricity there and at home well you certainly would have because if we recall how this operates the microprocessor is sending a little bit of electricity out through

the wires measures and monitors so when that electricity changes it activates and rings the chime it's not a power circuit it's not two wires connected to a transformer it's not like your standard - no doorbell the circuit that we drew on the whiteboard where the electricity is just flowing from a power transformer through the switch to the chime and back to the transformer again and there is constant and available voltage there the type of

circuit that you have when you have a chime module or a new tone electronic musical chime is a triggering circuit the voltage through the wires to the button is just a convenient byproduct of the design and it's not enough voltage and it's not enough power to power a ring video doorbell it simply will not work I know that's a really disappointing bit of information for you to hear if you're watching this but that's

sort of the facts of the situation to answer another question that comes up during these conversations and emails that I get about this topic no there isn't any type of simple component or device that you can add to what you have to make it work you can't add a resistor you can't add a diode you can't make some simple $2 change to the way all of this is designed and installed to accommodate

the ring video doorbell it simply doesn't exist so that's sort of the ins and outs of why you really can't connect a ring video doorbell to the wires that used to be on the back of the push button on your front porch if you have a new tone intercom system with a chime module or a new tone electronic musical chime you simply cannot have both devices wired together if you really want to

have a ring video doorbell I would screw command that you buy the standard one with the built-in rechargeable battery as I understand it the battery will last about a year with normal use and what it's time to recharge it actually notifies you and all you have to do is plug a little USB cable into it and plug it into a USB charger and it takes a few hours to charge it up

and you're good for year that's actually a lot less hassle than it is to try to modify your whole intercom system or your new tone door chime system to accommodate the ring video pro the pro is the model that doesn't have a battery built into it the standard one does I hope you found this video to be interesting and helpful if you did please give it a thumbs up on YouTube thumbs up if
