Mine has moved to 6 homes (starting when my grandfather purchased in in the early 1950's, now I inherited it.

Hi simisoundguy: The topic of Transformers that are installed in an attic is complicated. Typically is is not allowed if you have an attic that you must crawl around in (hands & knees) and it's full of insulation. The Transformer should never be buried in or covered over with insulation. Attic can get very hot during the summer, perhaps as much as 150 degrees. This is simply way to hot for a Transformer. If you have a walk-in attic with a platform or other flooring, it may meet electrical code to have the Transformer in the attic space. As for "fire risk" - your Transformer is not any more of a risk than it was before, when it was wired for a 2-Note Chime. In your original installation, the Pushbutton was not turning the Transformer on & off - it was simply completing the low-voltage circuit to make the Chime ring. In either configuration, the Transformer is always on. If you have concerns about the safety of your Transformer, hire a qualified, licensed Electrician to evaluate the situation and make a determination about it meeting the Electrical Code - Chris

Hi Lawrence; You're welcome - Chris

Hi Christopher: Your newly accquired LD49 is a 4-Wire Chime, there's no work-around for that fact - Depending on how your original Chime was wired - you may already have the wiring needed inside your wall - It is very common for there to be 2-wires that were run from the Trasnformer to the Chime and another 2-wires that were run from the pushbutton to the Chime. Watch this Video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YmROyFjML4M.html To understand how 2-Note Chimes can be wired If you inside the howl in your wall - you may find the 4th Wire that you need is spliced into the other wires Chris

Hi David: We already have the Video you need to watch - Here's a link: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YmROyFjML4M.html Chris

Hi CoastalSequimLiving: I would be best if you sent me a picture of the Chime Base (with the cover removed) and include your phone number - Email the pictures to: NSCOMPANY@MSN.COM - Chris

Hi HY-jo6vb: Yes, the 4-8 Note Connection is typically used for the Front Door connection - Chris

Also, gave it a thumbs up and subscribed!

Hi Charles: The Chime keeps ringing because the 2 different devices are not compatible with each other - Here's a Link to our Video that shows how the Camera must be installed to have to also operate the Chime - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8LXCcLr_HHA.html Chris

Hi Allie: There's not a lot of detailed information in your question, so I'll have to assume some of the basics. I going to guess that your original Chime was a standard 2-Note, ding-dong type of chime. I'm also going to assume that your mom's Chime is an 8-Note with either 4 long tubes or 3 short tube (since it has a COM connection. These are 2 very different types of Chimes and they have to be wired in a completely different way. Your original 2-Note Chime would have had only 2-wires connected to it (Trans & Front). Your mom's Chime is a 4-Wire Chime and is connected as I show in the Video you watched. If you simply connected the original 2-wires to the 1988 Chime (Com + some other screw) it may had created a short-circuit between the 2-wires (creating the spark). While I can say for certain, it is unlikely that it fried the Chime. The original wiring has to be sorted out to be able to make the correct connections - I can't really explain all of how to do that in a RU-vid comment - You will need to contact me directly for this type of help Finally, your original Transformer is 16 Volts AC rated at 10 Watts (VA) - (not 10 Amps ) What you will need is a 16 Volt AC Transformer rated at 30 Watts (VA) Chris nscompany@msn.com

Hi John: Nope - I've had mixed reports form different customers about the Arlo - Many have report that they were not able to get it to work like the Nest - Chris

Hi August: There is a Diagram on the Community Tab for this type of hookup - Here's a Link: ru-vid.com/show-UCcMN_sDzaDThDYRBb2Qcahwcommunity You should use a Transformer rated at 16 Volts AC with a Minimum of 30 Watts (VA) - Chris

HI HY-jo6VB: I couldn't tell you - The "Trans" and "Com" connections must be made to have the Chime work - Chris

Hi Carl: Here's a link to our Video that shows how to connect a Ring WiFi Video Door Bell to a NuTone Intercom system: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-HgpiZCPSbTA.html&lc=UgwvwRqi3ddjCrPiJqp4AaABAg The example is exactly the same - except you;re connecting to a Chime instead of an "Intercom Chime Module" - Chris

I ended up just buying the Ring wireless chime to avoid the headache.

Hi dejanpepovski: As far as I know, all of these WIFI Cameras are designed to use an AC Transformer to power them. It would not matter, in that case which way the 2-wiresa are connected - Chris

@@northsideservicecompany3567 Thank you

Hi Ron: That it correct. Since the chime is powered by an AC Power source (transformer) there is no polarity to the power. - Chris

sorry LC-42

@@JJ55Clingan It is perfectly alright to connect a single wire and the connect all of the other wires to the single wire - Chris

Hi Raja: Your wyze camera is not designed to have the ability to operate a standard mechanical or electronic door chime - so it will not be able to connect to your existing chime - Chris

Hi Aaron: How many different exterior doorbell pushbuttons does your house have? (ie. front - rear - side) - Chris

Hi danoj77: Your NuTone Chime is a Model LB56 made in 1972. Watch this Video - ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LqeyzBV-f0E.html It should shed some light on the problem you're having with your Chime - Chris

Hi Luiza: 3151 is not a NuTone Model Number - I have no idea who in Illinois can service your chime - You can contact me directly to discuss the problem and possible solution - Chris 925-743-8236

Hi John: You LC38 uses a 16 Volt AC - 30 Watt Transformer. The original NuTone Transformer was either a 301N or 301T. I have both Transformers in stock and I many have a cover - Chris 925-743-8236

Hi Danny: The Side Door Connection on your NuTone 8-Note Door Chime works in the same way that a standard 2-Note Door Chime works. When power is passed through the pushbutton (by pressing it) it applies power to the Side Door Solenoid. Connecting the Nest would be done exactly the same way that Nest shows when connecting to a 2-Note Door Chime. - Chris

@@northsideservicecompany3567 Thanks, I installed the Nest and it works perfectly with the side door chime. Do I dare install a second Nest Hello for the front door Westminster chime? :)

@@dworrell98 That depends - Is your 8-Note Chime the Fully Electronic Controlled versions (from about 1992 - 2010) or is it the type with the Telechron Motor? - Chris

@@northsideservicecompany3567 It's the Telechron motor build date May '83

@@dworrell98 Then, unfortunately the Nest will not work on the "front" connection - Chris

Hi AggieBQ: Yes - The Clock gets power from the "Trans" and "Com" terminals - Chris

Hi Patrick: It's really all in the Video - watch and see. The short answer is that you cannot simply connect up to the existing wiring to have it all work together - Chris

@@northsideservicecompany3567 Thanks for the reply, I watched the whole video a few times and understand how the chime works. My question applies specifically to the Ring video doorbells. Typical buttons that just complete the circuit are easy to understand as one wire goes to COM and the other to FRONT. When the button is pressed it completes a circuit and the chime does it's thing. However with a Ring doorbell, it too needs to be powered, and simply hooking it to COM and FRONT, won't power it (at least it isn't for me, others may have different results than I do). That is what I was getting at... How do you power this chime, a Ring video doorbell, and have the Ring unit be able to activate the chime. If it's even possible...

Hi Tanner: A NuTone 8-Note Chie is a 4-Wire Chime - As the Video shows, you must have constant power from the Transformer to the Chime - And the Pushbutton wires must run directly to the Chime - I suggest that look inside the wall to see if there are more wires - perhaps they were spliced together for the original 2-Note Chime - Chris

@@northsideservicecompany3567 I figured it out! Turns out the 2 black wires twisted together were the 2 wires I needed to hook up to comm. It works and it sounds glorious. It'll surely shake the dust from the light fixtures in my little townhouse.

@@Lincolntowncoupe Well Done - You can use the "Volume" control to adjust how hard the plungers strike the tubes - Chris

Hi Edward: It sounds like you have one of the following problems - wiring - broken pushbutton - defective Chime.. Try the following ~ using a short piece of wire, jumper between the "Common" and "Front" terminal on the Chime, if it rings the Chime is good, if not, the Chime is defective. ~ Remove the Front Pushbutton and disconnect the 2-wires, touch them together and see if the Chime rings (btw - the lighted buttons should not have LED's in them) - Chris

@@northsideservicecompany3567 Hi Chris: Thank you for getting back to me so quickly. I tried your troubleshooting suggestions. The jumper sounded the chime. Crossing the switch wires did not. It turns out I had the transformer wire hooked to a chime terminal. I didn't think that was possible since I could get the back door to ring any of the chimes. Thank you for the great advise. Wife is happy!

@@edwardbrenner7654 The difference between the "Front" terminals and the "Side" & "Rear" Terminals is: The "Front" connection activates the Westminster timing circuit (all electronic) the "Rear" & "Side" connections are simple circuit - which allows power to be applied to the appropriate solenoid when the pushbutton is pressed. - Chris

Hi icemorons: The EXT. Front connection is used to activate a second Chime, which can be either a 8-Note or 2-Note Chime. To see how this is wired - Go to the Wiring Diagram on the Community Tab of our RU-vid Home Page - Here's a link to the diagram: ru-vid.com/show-UCcMN_sDzaDThDYRBb2Qcahwcommunity?lb=UgxvTh9HzD0dL89jV8J4AaABCQ Your 2nd question is interesting may offers clues as to why your Side Door Pushbutton isn't working. Transformers rarely fail suddenly all on their own. Transformers are almost always causalities of a failure in the device they are powering. It could be possible that you suddenly have a short in your Chime Wiring - it is also possible that either your 8-Note Chime has a problem or you may have a shorted or stuck pushbutton. Since you didn't test the Side Door or Front Door of your 8-Note Chime, we can't know if those are working correctly. The way your 8-Note Chime is designed, the Rear and Side Door connections are "wired" directly through their Pushbuttons - which means that when the button is pressed - it simply applies power to either of those solenoids. As a simply way to test the 8-Note Chime - connect the 16 volt power from the Transformer to the Chime - using a short jumper wire - jumper between the "Com" and "Front" terminals - the Chime should ring. Repeat this test for the "Rear" and "Side" connections - they should work also. If any of these do not work - your Chime has a problem. As for "wiring problems" - Any shorted wire in the system will likely drag down the voltage from the Transformer - Approaching this in a step-by-step method will be best: Connect the Transformer wires to the Chime - measure the voltage at the Chime - it should be between 16.8 - 18.9 volts AC - Then connect the wire for the "Front" connections - measure the voltage again, it should be the same as before. Then make the "Side" connections - measure the voltage - it should be the same as before - the make the "Rear" connections - measure the voltage, it should be the same. If at any time the voltage drop to near zero after making a new connection - there may be a short in those wires - Chris

@@northsideservicecompany3567 Thanks for the great suggestions. I'll be troubleshooting this further today, most likely.

@@icemorons5678 Best of luck with the Troubleshooting - Chris

Hi Zachary: Your Transformer could be anywhere - Most common places are: Garage, Circuit Breaker Panel, Furnace Closet, Water Heater Closet, Attic, Basement, Ceiling of a closet inside the house. Usually it will be fairly close to the Chime (ie. They wouldn't have put it 100' away and run the low-voltage wires that far) When trying to figure out what was done by someone before you - the Rule is "Installer are Lazy" whatever was the easiest way to do it - it probably how it was done - Chris

Northside Service Company thank you very much!

Hi Tony: I don't really understand the question - I need some context as to what you're asking about - Chris

@@northsideservicecompany3567 When original transformer burnt out electrician replaced it with bigger one. saying it'll last long time. The chime has been working well since. So I was wondering if the replacement was too big for the chime.

@@tonyhwang3888 Your Chime is a 16 volt Chime - The 24 volt transformer is wrong - too high of voltage - it will damage the Chime over time. The 40 VA is fine (but unnecessary) a 30 VA is a good choice - Chris

@@northsideservicecompany3567 Thanks. Just ordered 16V one from Amazon.

Hi Jeff: Based on your description - you do not have a NuTone Chime. NuTone Chimes do not use labeling like "Terminal A" - "Terminal B" and so forth. I can't tell you how to connect up your Chime because I have no idea what it is - Chris
