I wired it as noted in the video. It worked for months. For some reason, all the sudden the chime stopped working. The camera still worked fine and I got notifications on my phone. I ordered a new Nest doorbell camera. Wired it exactly the same. Chime didn't work. Several weeks of frustration ensued and one out of 30 rings the chime, somehow would sound. I installed a dedicated transformer to the Nest Hello and that didn't help. (I had previously been using one of the 2 transformers in the Nutone main control box.) Finally, I checked the comments on here and found one that reminded the reader to "TURN ON" the CHIME ON/OFF selector on the Nest App. Problem solved and a beer was enjoyed. I suspect that either the app was updated and defaulted to "OFF" or I failed to notice the setting when I installed the new doorbell camera. Great video! I never would have been able to pull this off without your help.

[@northsideservicecompany3567]

Hi topco: Well Done! The settings in the app trip-up lots of people, it would be more helpful if the companies who make the Cameras provided decent documentaion instead of cartoony drawnings about what to do (just my take on it) - Chris

[@jamesfredregill8147]

Thank you Chris for the explanation. I bought the parts and made my own board. I powered the Nest Hello by running power using the speaker wires since I was removing the outdoor station. Camera works great. I could not get the Nutone chime to operate and after much troubleshooting I was stumped. The Nest chime adapter was not providing any voltage to the relay board. I finally jumpered AC voltage from the transformer directly to the relay board and it triggered the indoor chime! I finally figured out the problem and that’s why I’m posting. TURN ON the “ Indoor chime On/Off” from the nest camera menu! System works perfectly. I connected relay board directly to the chime module and all parts are in the Nutone unit in the house. I could have installed this with just 2 wires since I don’t need the old doorbell button with the relay hooked up directly to the chime module. Thanks again!!!

[@northsideservicecompany3567]

Hi james: Nest loves to hide setting in the menu for the app - I've had some customers who had chimes that would not stop ringing because the duration time in the app was set to infinite - Chris

Thanks for this! I bought a Nest Hello not thinking about how our intercom system is different from a "normal" doorbell. I actually have an IST intercom, but the basics were the same. I was also able to find an inexpensive and small 12V AC relay which works great. The tough part was getting the wires run to where I needed them, but after that, everything went together easy. Thanks again!

[@keepthattomyself]

I should clarify that I removed the speaker and replaced the existing intercom panel with a plate made to mount the Nest Hello on. I tucked the original circuit board, now tied via relay to the Hello, behind the plate.

[@mopac001]

Chris, this video was simply outstanding and so much help with a project I'm contemplating. From looking at some of your other videos I think what I have is a base like your video on the K44 long tube Majestic from 1947 except the base is inside a much fancier unit than the Majestic. It's a wood cabinet much like a mantle clock, including the clock. The clock face and it's glass cover are part of a door that opens to allow access to the chime base. Where your majestic video showed a lightbulb illuminating the Majestic cover from inside, my unit has the same connector but instead of a light bulb that's where the clock motor plugs in. I believe my grandfather installed this in the late 40's as it was already "old" when I first encountered it as a child in the 60's. After my grandparents passed I removed it and it's transformer to install in a house we were building, now 20 years ago. It reminds me of my grandparents every time someone comes to the door. The clock still works too. The transformer is the original. And although it says 20 Volt 20VA on it, when I test it with a multi-meter the transformer is putting out 28 Volts. So I now want to install a modern Ubiquity G4 Doorbell Pro with camera. (Like the NEST doorbells and others.) It includes a power device for activating an external doorbell very much like the one NEST provides that you have in your video above. The specs on the doorbell camera indicate it can use 16-24VAC. I've read people who've had the cameras fail after awhile when powered by 24VAC doorbell transformers where the actual voltage was more like 28VAC. So I don't want to power the new doorbell camera with the 70 year old NuTone transformer putting out 28VAC. And after 70 years I don't want to use a different transformer on the 8 chime doorbell. I almost thought I was out of luck until coming across this video. Using a relay I can get a new 16VAC transformer and let it handle the doorbell camera it's meant to handle and still let the the NuTone transformer handle the 8 chime as it has for the last 70 years. It's brilliant! The best of old and new working together!

[@northsideservicecompany3567]

Hi mopac001: Transformer Voltage Ratings are specified with the Transformer under it's maximum rated load - a free-running Transformer will typically have a higher voltage measurement. Also, line voltage today is higher than it was decades ago, the higher the line voltage - the higher the Transformer voltage. I am not familiar with the Ubiquity Camera you mention - for it to activate the Chime correctly, it will need to have an adjustment in its app for what Nest calls the "duration time" . This set the amount of time that the relay will stay energized. Your Clock Chime needs a 3-4 second duration time to allow it to start and run through the sequence. Chris

[@mopac001]

​@@northsideservicecompany3567 Chris - I'll ask on their support page about a duration setting. I do know there is a setting on whether it's a mechanical or digital chime attached to it. And it does list some Broan-NuTone mechanical chimes that are compatible - LA126WH, LA11WH and LA39WH. The only other Broan-NuTone listed is LA600WH which is a digital chime. I'm guessing behind the scenes the setting for mechanical or digital will have to do with how long the relay stays energized. Hopefully someone on their support page can tell me how long that duration is.

Wander what might be wrong?

[@northsideservicecompany3567]

@@jimpluss2009 What you need to do is measure the voltage that's coming out of the module that is connected to the relay ( with the relay disconnected) If the voltage is correct (probably between 16 - 24 volts AC) the relay should energize. If it does not - check to make sure the voltage of the relay coil is correct for the available voltage. If all of that is correct - it could be that there isn't enough current (power) available from the module to energize the coil - in this case you may need a different relay - Chris

[@jimpluss2009]

Thank you Chris. The relay I use 15 A 120 VAC. I’ll check the power out of module.

Chris, your instructional vidoes are some of the best I've seen on KZbin! VERY well done! I do have a question: The Ring Pro has a Pro Power Kit that ensures that the Ring Video Doorbell Pro gets the power it needs. I assuming this is similar to the Nest Power module correct? The only difference i see is the Nest Power Module has 4 wires and the Pro Power Kit only has two. How does the wiring work with only two wires?

[@northsideservicecompany3567]

Hi Scott: I have not worked with any WiFi Camera that uses a 2-wire power module and it would be a mistake to assume it will work in the same way a 4-wire module does. I have had several people report the 2-wire modules (from brands other than Ring) would not work to energize the Relay that is needed to active the Chime Module in a NuTone Intercom. - Chris

[@indianboy0453]

Awesome video with great detailed instructions! Thanks for that! I was curious about something though. Rather than install a video doorbell, would it be possible to attach dc voltage monitor of sorts to the chime module and feed the readings to a smart home software, like home assistant for doorbell notifications? Im kinda cheap and I do value a bit of video privacy, plus I like doing things on my own. Cheers and thanks for the awesome resources!

[@northsideservicecompany3567]

Hi Indianboy04: I suppose it would be possible - however it would be a completely custom setup. Probably more trouble than it would be more trouble than it's worth. I believe there are a few door cameras that tie into the owners network (either wi-fi or Ethernet) directly and bypass any connection to the "internet". I think this would give you a fair amount of privacy - Chris

Thanks for taking the time to explain things to us! I've owned the Nest Hello (wired) for months, but been too daunted to actually take steps to install it. I have the Nutone LA-52 musical chime (which you mention in the video), but it seems to be already hooked up to a Nutone 105-N 15VA 16V transformer in the basement. (It produces a musical chime when the front doorbell is pressed, and a simple two-tone when the back doorbell is pressed.) Does this means I can simply follow the Google instructions straightforwardly (using the provided chime connector but without need for a relay), as the transformer seems to be in the proper range already? Many thanks!

[@northsideservicecompany3567]

Hi khalid: The installation of a Nest Camera should be done as Nests describes when you have a standard door chime. The NuTone LA52 is wired as any conventional 2-Note Door Chime would be, so I don't think a relay is needed (although I haven't actually done it before). Th eLA52 requires a Diode across the Pushbutton terminals (it allows the song to play fully once the button is released) I'm not sure if this will cause by issues with the Nest Camera - Chris

[@scorpion251075]

Hi Chris, Absolutely outstanding!!! Thank you so very much, I learned a lot from you! I do have a question though! I have a mechanical old chime the same one you showed in section one. I successfully connected my Google Hello Doorbell to my old mechanical Chime (of course using the capacitor that came with the Google Hello Doorbell) and worked fine. Now I decided to upgrade the old chime to an electronic MP3 Nutone chime that I bought from Amazon which simply advises to take the old mechanical chime wires F & T and connect them to slots provided on the MP3 chime system AND they provided a diod to put in parallel connection to (as they say) provide continuous power to the MP3 chime system. All these of thr instructions in the manual were for a regular mechanical button type doorbell (the same one you showed in section one). So I connected the wires as the advised (but now I have the Google Hello Doorbell) and nothing worked. My question is: Should I use the capacitor provided with Google Hello Doorbell PLUS the diode provided with the electronic MP3 chime?

[@northsideservicecompany3567]

Hi Scorpion Ninja: I'm assuming that your have a NuTone Model LA600WH MP3 Chime - The instruction that Nest gave your seem correct - The problem may be with how your installed the Diode. On Page 2 of the LA600 instructions, it shows how the Diode gets installed across the screws on the pushbutton - Which direction the get installed in (where the anode is placed) depends entirely on which way makes it work properly. I suspect that you don't have the Diode - 1. Across the "button terminals" or 2. The Diode is the wrong-way around. You can print out a copy of the LA600 Installation instructions for the NuTone web site. - Also, I believe in the Camera App - you have to set the Chime as either "mechanical" or "electronic" and also you have to set the "duration" time - Chris

[@mathewlitchi7247]

Thank you for this great video. Will this work if i take out the old chime button and just leave the nest hello?

Thanks for the great video.

Do you have another video or schematic for how you set that up? It might be easy but I don't understand it well enough to do it without some guidance. Thanks again!

Hi Kris: This Video explains everything as much is is possible on what to do - The actual physical Installation will vary from systems to system - so I can't really show everyone what to do exactly.

Thanks for this excellent video that explains all so very clearly. I would like to do the same but I'm having difficulty finding a 16 vac relay. 12 and 24 vac relays seem to be more common.

[@northsideservicecompany3567]

Hi Stephen: The easy solution - as I show in the Video is to use a 12 volt DC Relay with a rectifier - Chris

Thanks for your response Chris and I will likely go that route. However, I was wondering if there are any issues, i.e. to the chime and possibly frying it in some way if I went the way of 24 v transformer and 24 vac relay.

[@maxliv0308]

Hi Chris, thanks again for making a video with actual parts, helps a lot for a non technical guy like me. I think that 90% percent of people out there want to remove the speaker and button entirely and replace it with Nest or Ring etc... I bought a custom plate that fits right over the casing, in this case do I just connect the wires going to the existing chime button of the Nutone door speaker straight to the relay?

[@northsideservicecompany3567]

Hi maxliv0308: Yes - you would connect the wires from the original push button to the relay - I would recommend that you leave the NuTone Door Speaker in place (put the WiFi door camera next to it) - by removing it, you loose the ability to answer the front door with the Intercom System.

[@pcm1ke]

Thank you for posting this video, it’s really helped me learn a lot. I have a few questions... First, would it be possible to simply disconnect the wires from the chime module and connect them to one of the two transformers in order to power a nest video doorbell at the front door or would that cause the rest of the intercom to not function? Basically, is there enough power from one of the transformers to power both the video doorbell and whatever it’s powering on the 3303 main intercom unit? I know the nutone station outside wouldn’t be functional, but I’m ok with that. Also, another thing I was considering was using the two wires that power the intercom SPEAKER at the front door and attaching those to one of the transformers and then using those to power the nest video doorbell and then wiring up the rest of the nestintercom as laid out in this video to get both the intercom chime and the video doorbell working WITHOUT running new power wires and a new transformer just for the doorbell. Does the chime module have to sense the speaker in order to function? I don’t really have a use for the intercom speaker outside once I have the video doorbell working, but it would be nice to have the nutone chime work as well. Problem is it would be rather costly and really difficult to run a new power wire and transformer. Is this a workable option? Thanks in advance for any advice!

[@northsideservicecompany3567]

Hi pcm1ke: Yes you can disconnect the Door Speaker wires and use them as power wires for the Nest. You will have to ask Nest about the power requirements for their product - Chris

[@who6222]

First Chris, thanks so much for this video. I've watched this one now as well as the 2 earlier ones you made on this general topic. Very informative and I know much more now than I did. That said, I think the path described in this comment is the one I'm on as well. I have an M&S MC602 system that was in the house when we bought it 10 years ago. We never use it all, except for the doorbell because the house wasn't built with a traditional doorbell. So I just want to replace the existing door speaker and button with the Nest Hello and then leverage the chime module in the existing M&S system. From what I'm learning, it seems like I should be able to do that, but I'm not 100% sure what additional components I still do / don't need. If I can use the door speaker wires for power (still to be tested and confirmed), I assume then I don't need the new transformer. However, I believe I do still need the relay (per your input to another comment) and the Nest chime connector. I'm going to start down this path and see what happens, but Chris if you have any additional guidance or gotchas that I should keep in mind, I'd appreciate the input. Thanks again for taking the time to put these videos together.

[@robertk9908]

Chris, Great and very helpful video for me (non-electrical). I have the same Nutone intercom as shown in the video and hooked up the Nest Hello using your wiring diagram with some uncertain exceptions. After following the wiring diagram, the camera now work on the Nest app but the Nutone chime does not work. The Nest app indicates "Indoor chime on". I connected the wiring to an existing low voltage transformer in the garage for the central vacuum system. The transformer is 16V AC 30VA. I plan to purchase and connect to a separate 16V 15VA transformer. The other uncertainty is the wiring connection to the URBEST HH52P AC 24V relay. I connected two wiring to one end of the relay to the pushbutton (tossed out the exterior speaker cover plate) and connected two wires to the other end of the relay to the Nest power device. I saw another video where the installer used the same URBEST relay but it appeared the two wires from the pushbutton were each connected to opposite ends of the relay. Before I consider purchasing and rewiring the entire setup with a OhmKat Video Doorbell Power Supply and electronic chime, can you provide any suggestions on what I might be doing incorrectly?

[@northsideservicecompany3567]

Hi Robert: If you're going to add an additional dedicated Transformer, it should be 16 Volts AC rated at 30 or 40 Watts (VA). I'm unclear on why you're using s 24 volt relay on a "16 volt" system???? There is a reason behind the Relay choice I made for use on our "Relay Boards" - You have to look at the amount of current required to energize the coil in the Relay. Many AC relays are simple to big for this type of application - I choose a small DC Relay because - 1. These are used in many NuTone Intercoms and we already had them in stock - 2. Their small coil requires a small amount of current to energized the coil - placing a smaller demand on the Nest Power Device - 3. Their small physical size makes it easy to install in the original Entry Door Station Rough-in. - Chris

This is very well written up and illustrated. Just one question couldn't you just put the relay behind the master station, you could find the wires for the push button and put them on the relay there. Then attach to the transformer at the intercom then you would just have 2 wires going out to the door bell and wouldn't need to add an extra transformer, I could be wrong and might of missed something in the video. Once again it was well demonstrated.

Thanks for posting this very informative video. But why do you still need the original door speaker when you have the wifi camera doorbell, which usually comes with its own speaker? If you replace the original speaker with the Wifi doorbell, seems like no new wires would be needed. For example: - disconnect 2 push-button wires at chime unit - remove the existing door speaker and replace with Wifi door bell connecting to the 2 existing wires - locate the Nest power module and relay next to the chime unit (if there's enough room). - connect the 2 wires removed from chime unit earlier, and reconnect one wire to the Nest power unit, and the other wire to the transformer - connect other side of Nest power unit to one side of relay, and also connect Nest power unit to remaining terminal on transformer (all as shown in your figure) - connect other side of relay to the two terminals on the chime unit using a couple of short wires - instead of using a newly installed dedicated transformer for the Wifi doorbell, I'm wondering whether I can just upgrade the exiting 16V transformer to a higher VA one. I currently have a model 105T transformer, which I think is rated at 15VA or something like that. I was thinking of replacing with a 16V / 30VA. What do you think? Do you think this will work? I'm actually looking at the Amcrest video doorbell ($99 at Amazon, and good reviews from various sources). Spec says it requires 16V-24V AC input, but doesn't mention VA requirements. All spec says is that if doing a new install, a transformer rated at 16V / 30VA would work. What's the power requirement of a typical Nutone unit? I have a Nutone 3003 series intercom system. I'm not sure of the chime unit model number; I can't seem to find a number start with "LM" on the unit. All I see is "ACPC-83 94V-0."

Hi Chris. Excellent video and instructions-as usual. Two questions.

Also, does the relay you linked above require a bridge rectifier? If so, can you recommend one that doesn't need that extra component? Thanks!

[@northsideservicecompany3567]

Hi Kelly: You can remove the NuTone Entry Door Station completely and just connect to the wires that activate the Chime Module. The relay I used is a DC Relay - so the rectifier converts the AC voltage from the Power Module to DC to power the relay. I choose the DC relay because the selection of AC relays is much more limited, much more expensive and the AC relays are much much bigger in size (also, it's what I had on hand :) ) - Chris

@@northsideservicecompany3567 to clarify - -Since i have this request but the owner wants to do away with the chime feature of the Doorbell but maintain the inter-room communication of the intercom - to bypass the front speaker/doorbell that still requires the Relay to close the circuit as shown in 26:00 or so - But then I still need to find a place for the transformer, correct? If not, then I think if they are only concerned about correct voltage to the Nest and not the mechanical chime at all, I can simply add the transformer without the relay.

I have a high quality 16v 15A transformer dedicated to the Hello circuit, and have also tried various brands and sizes of transformer to rule out spotty power, with the same result. I also wired the Hello directly to the transformer to isolate it from the rest of the configuration, with the same result. Does the length of wire play a role?

Hey there! Thank you so much for this video. I am trying to set up a doorbell in a situation like this with an electronic chime and intercom system. I set it up with an AC relay. I bought the smallest one I could find, but the output from the doorbell still doesn’t seem strong enough to close the coil. When I attach the 24v transformer directly to coil, it closes fine. But when I attach it to the doorbell, with the little circle module of course, and press the button on the doorbell the coil just vibrates for a second and then stops. It never closes, and so the relay never switches to activate the chime. According to the manufacturer the relay only needs 17mA at 24v to close. I tried finding and AC relay that has a lower power requirement to close, but can’t find any. Do you know of any AC relays that might work, or do you think I need to use a rectifier and DC relay to make it work?

I ordered the relay and rectifier you had links too but just a little fuzzy on the hook up of the supplied nest (puck) the newer ones have a white wire and a gray wire on one side of puck and the same on the other side of puck. so at time 26:03 of video, it seems you are showing transformer wire going into one color of one side of puck and coming out of other wire and color of same side of puck going to doorbell. if you could verify or correct me on that it will automatically explain the other side going to rectifier. thank you.

[@northsideservicecompany3567]

Hi Roger: As shown in the diagram on the White Board - Power from 1 wire of the Transformer flows through the Nest puck and continues on to the Nest Camera. The 2nd pair of wires from the Nest puck are connected to the rectifier leads on the Relay Board. The concept is simple - this is how Nest wants you to make up these connections - if you were using the Nest puck to activate the coil in a standard, 2-note mechanical doorbell. In our example - your are activating the coil in the relay - which closes the contact of the Relay - thus ringing the C8 Chime Module in your M&S System. I always like tricking the Nest to do what I want. . . - Chris

Hi Sam: Your installation sounds much more complicated that average since you have 3 doorbells - How these 3 doorbells were wired to have them all ring together is a complicated topic and without you knowing exactly how it was done - you don't enough information to have the Nest work with them - Creating a wiring diagram for just the 3 doorbells would be the first step - then based on what you then know - figure out how to incorporate the Nest into the door bell system - Very few doorbells operate on 24 volts - typically they are 16 volt devices.

Hello. Nice explanation video BTW. Quick question. Since the NuTone Music Intercom uses a 4 wire system (2 for speaker and 2 for doorbell button) have you considered disconnecting the 2 wires used for the speaker and use them to power the Nest Video Doorbell by connecting the not used speaker cable pair to the 16V AC out of one of the already available Nutone Original System? Obviously the speaker wires will be disconnected from the speaker connection at the Music station and removed from the actual speaker at doorbell. Actually the whole doorbell speaker station will be removed (speaker and button) and be replaced by the new Nest and relay setup. I have an M&S DMC-1 Music Intercom System which appears to be the same setup as the NuTone Music with 10 stations and do not have a lot of space to place the transformer. All the stations and doorbell goes in a home run setup to the central music intercom rough in and there is no space there. So I was thinking about removing the speaker cables to power the Nest if I end up purchasing one of those fancy video doorbells. If not maybe run second pair or wires from the intercom transformer to the new video doorbell. Just need to identify the 2 wires for the 16VAC 37W output of one of the two transformers.

Hi Jose: Many people give up the Door Station communication - so they can reuse those wires to power the Video Door Camera.

Great video that I've shared with my electrician so he can set this up with my NuTone electronic door chime/intercom system. But before he does that, here's a question I didn't see addressed in your video: Will I still be able to use my NuTone intercom station inside my house, to speak to the visitor through the Nest Hello doorbell's speaker? I am really hoping I can continue to use the NuTone intercom station when I want to, otherwise I will always have to have my cell phone on and with me to speak to a visitor at my door. Does the wiring set-up you show in the video, for the nutone electronic door chime, allow speaking between the interior nutone intercom station and the exterior nest hello doorbell's speaker? Thanks for your reply!

[@northsideservicecompany3567]

Hi Curious D: No - even if you install the Nest Hello as shown in the Video - there will not be any voice communication possible between the NuTone Intercom System and the Nest Hello. If the installation is done as shown in the Video - the Nest Hello will ring the Chime in the Intercom. If you desire to keep the voice communication through the Intercom System to the Front Door - you can put the Nest Hello next to the original NuTone Entry Door Station and have them both work fully. - Chris

@@northsideservicecompany3567 Thanks for your quick reply, Chris! Can you briefly explain how the nest system and the existing nutone system would each be wired so that the nest doorbell and the nutone door srtation can be "next to each other" outside? And in that set-up, would speaking only be done via the nutone intercom & door station, while viewing would be done via the nest camera & app? On the other hand, if I decide to skip putting them next to each other and use just the nest / nutone wiring as per your video, then all speaking and viewing would only be through the nest app, right?

Hi Eddie: Without more detailed information about your System, I can't really give your specific advise. If you can answer the following questions, I'll try to help: 1. What Model System do you have? 2. When was it installed? 3. Is it the original System from when the house was built - or is it an upgrade to the original System? 4. Does it have a Chime Module built into the Master Station (you hear it ring through the remote stations)? 4a. If it doesn't have a Chime Module - is there a Door Bell on the wall somewhere in the house? 4b. If there is a Door Bell on the wall - is it a 2-Note Chime (ding-dong) or is it Electronic (plays a song)? Please let me know Chris

This was an excellent educational video. Can I actually replace the Nutone door intercom with the Nest hello wi-fi camera (it appears we are adding it here)? I have IR-3303 central station with seven intercom portals around the house, in addition to the door unit exactly the same as in your video. Six wires lead to that unit of which only four are used. To folow teh 4-wire route, can I replace the door unit in its entirety with the Nest (or Ring, or Arlo) doorbell camera? If so, could i just eliminate the door speaker unit on your WB display for phase 3 (27:14) and lead those wires directly to the chime module? Thank you in advance.

Hi kenozoik7168: Answers to your questions: 1 - Yes you can replace the original NuTone Entry Door Station completely with your new wifi Camera if you wish. 2 - You can use whichever Camera you'd like, as long as it has ability to be installed in a way that could "ring a standard mechanical 1-note door bell (ding-dong type)" For Questions 3 you said in your comment - "i just eliminate the door speaker unit on your WB display for phase 3 - I have no idea what this means.

Is it okay to remove the old button from the new setup and have the output of the Relay Rectifier board connect straight to the two contacts on the Nutone Chime module? Or is the button necessary because it acts as some type of resistor? I am connecting a Ubiquiti Unifi G4 Doorbell to a Nutone IM-440 system.

What about if I just want to bypass my NuTone LA174 Chime completely but still use the existing wires from transformer and front doorbell to power a Ring Doorbell Pro and use a Ring Chime as my Digital chime? When I look at the recessed box/NuTone Panel, I see one Red Wire attached to the "Front" on the NuTone Chime and I think the other wire coming from the front doorbell is crimped to a wire coming from the transformer. It looks like the transformer wires are connected to the yellow/green wires on the NU174 PCB.

Hi Chris, Great info! I have a NuTone 174 with 2 pairs of wires. I pair (Red and white let's name it as pair AA ) producing 18v and the other pair (pair BB )doesn’t produce any. Both pairs’ whites are connected to Yellow, One Red to the ( AA redwire, Power producing one) and the other Red wire to the 1st door on the circuit board. In the garage I have a transformer, if pair BB is connected to the Nutone then I get voltage at the doorbell. (as rated by the garage transformer) . So it looks like I have 2 power sources. I get voltage at the doorbell if and only if pair BB is connected to the Nutone system. My question is, given this, where do I connect the Nest power device and relay ?

[@northsideservicecompany3567]

Hi omnamahshivaya7007: Your LA174 is wired in a conventical way, as any Chime which requires constant power would be wired. 1-Pair of wires from the Transformer supply constant power directly to the Chime. The 2nd pair of wires come from the Pushbutton, which activates the Chime when the button is pressed. There are no "power wires" outside at the Pushbutton - The wires that are connected to the Pushbutton are the "Trigger" wires, which tell the Microprocessor in the Chime to activate. Your Camera must be installed exactly as I show in our Video(s) - which includes adding a 2nd Transformer to power the Camera - running wires for the new Transformer to the Camera - including whichever "power device" comes with the camera - adding a Relay between the "Camera System" and the LA174 for activation - Chris

Some people are mentioning repurposing the red/black speakers wires for powering the smart doorbell since it's no longer needed. Is this advisable and what are the steps?

[@northsideservicecompany3567]

Hi jack: If you're installing the WIFI Camera in place of the original Entry Door Station, you will be giving up the Intercom Communication to the Door Station becuase the Door Speaker Cone will have been removed. This means that to 2-wires that connected the Door Speaker Cone to the Master Station are no longer being used and they can be "reused" for a different purpose - like becomming power wires to power the WIFI Camera Specifically what needs to be done will depend on which Brand and Model of Intercom you have - however here are the basic steps ~ more-or-less ~ 1 Locate the "Door Speaker" wires behind the Intercom Master Station 2 Disconnect those wires from the Intercom System 3 Add a new dedicated Transformer that will be used to power the WIFI Camera 4 Connect the previouly used "Door Speaker" wires to the new Transformer How you deal with the Transformer that will power the WIFI Camera depends entirely on what Brand and Model of Intercom you have - some are easy - some are difficult and some are impossible - I cannot address all of the possibilities in a KZbin responce Chris

Hello Chris thank you for the content. I have a Nutone LA310CY 8note chime. I’m trying to do what you did in section 2 where a new smart doorbell will work but also work the existing chime. This doorbell is a Arlo wired doorbell. They give a module with 2 wires that go inside the chime like your video. My instructions don’t have me remove any wires. Only add my 2 from the module to front and trans with the existing wires still there. Once I turn the breaker back on the existing chime rings constantly. The Arlo powers up but the nutone just keeps ringing. I guess the circuit is staying closed. Do you have a wiring suggestion that may work?
