Hi allwright: Sounds like an intersting project. I'm not sure if there's a market for repalcement button caps - I would think that they would need to be sold as a complete set, so everything matches. The Gold or Silver finish may be difficult to reproduce, Black would probably be the best replacement color - Chris

Hi RogeneBunjer: I'm glad the Video helped you get your Door Chime working - Chris

Hi david: Polymer Batteries have a 300 - 500 full charge cycle life - so how long it will last depends on how mnay power outages you have - Chris

Hi jinks67: You're welcome - Chris

Hi wrthrash: The Dusk-to-Dawn lamps are not typically used in low-voltage landscape lighting - Chris

Hi kkp4297: On M&S Intercom Systems a constant clciking of the Inercom Relays is often caused by switch problems in Remote Stations or Wiring problems - or both - Chris

Hi JT-gq1cn: You could add an "On / Off" switch to the Chime - Chris

Hi rjr6860: To direct you on what to do and how to do it - I need much more specific information about your Chime - It would be best if you contacted us directly - Chris nscompany@msn.com

Hi Roger: I would guess that the control board has been damaged and since Malibu is out-of-business, there no parts available - Chris

Thanks for your reply. I did contact Amazon where I bought it from to see if they would do anything. No word yet. I guess I could still use the Malibu if I hooked it up to a timer. We’ll see. Temporarily I added the ten additional lights to another transformer in use but I have too many lights on one transformer. Have to give it more thought. Thanks again! Ski

Hi Beavis-s5x: Using a 45-ohm Speaker Cone will not damaged the IM4006, however the lower impedance of the Speaker Cone will result in a lower sound level from the Speaker - The sound level will probably be somewhere in the 40 - 50% range. 25-ohm Speaker Cones are not diffcilt to find, if you wanted to replace it - Chris

Hi 2012-v9b: What you're describing seems odd and not normal. Typically a "howling" noise would be related more the the "Intercom Volume" setting than the System Volume. Howling usually indicates some type of feedback with the Intercom function. Do you normally keep the 2 Remote Stations in the "Radio / Intercom" on the IM4006 (room-control switches)? The troubleshooting would be to disconnect the wiring to the 2 Remote Station - from the Terminal Board (not at the remotes) Then set the System Volume to the desired level and use the Master Station - Then reconnect just 1 Remote Station - Test the System again - Then add the 2nd Remote (having disconnected the 1st remote) and test - I think you have either a Wiring or Remote Station problem (however since your IM4006 is at least 28 years old - it could also have problems) - Chris

ahh, I found the problem… somehow overtime a connector was plugged out of a bored. I plugged it back in, hooked it up and it works fine now. It was just strange to me because it got a full rebuild 4 months ago.

Hi Mobius: If a constant power source is required to keep the battery charged - then you need a separate Transformer - I don't know anything about a 250-ohm resistor Since you left 2 comments on this Video - I suspect that you are trying to figure out a 'work around" for what I show in the Video - What I show is "tried-and-true" and many hundreds have followed it with suscess (as far as I know) - Chris

@northsideservicecompany3567 Regarding my comment on whether one need a new dedicated transformer, of course having one will work. What I am saying is, for some doorbell model with battery, the wire only trickle charge so the power requirement is low, compared to say Ring video doorbell pro wired where there is no battery. In the former case you can just reuse the transformer of the existing old intercom system and not likely cause any overloading. This save money getting a new separate transformer. In the latter case of some video camera model without battery, the higher power draw make sense to have dedicated transformer. It depends on the doorbell power draw.

Hi Mobius: Becasue the Relay is a DC Relay - A DC Relay was choosen becuse it is a much large selctions of small, low-power, low-current DC Relays than there are AC Relays - Chris

@@northsideservicecompany3567 Thanks that makes sense. I got myself an AC relay which I will test, but I can see a DC relay with rectifier maybe cheaper. I am not sure my AC relay would work as the trickle charge may trigger the relay without the doorbell being pressed. I will report back.

@northsideservicecompany3567 yes the AC relay I got will trigger always leading to constant chime. How do I order your rectifier and relay board? Can I buy one from you?

I manage to get R1BU1C AC relay to work. I connected the AC solenoid side in parallel. The shorting when ring is pressed de-energises the parallelly connected relay and the normally closed pole switch is actuated to the normally open position, closing the normally open SPDT circuit where the cold traditional chime button circuit is wired to.

Hi vipjeffvegas: You can contact us directly to order the External Audio Jack - Chris nscompany@msn.com

Hi vipjeffvegas: There is no "out-of-the-box" solution to permanently add Bluetooth to the 2542 - The simplest solution is to add an External Audio Jack - ruclips.net/video/xrlYjIl6yng/видео.html After adding the Audio Jack - you can purchase a Bluetooth Receiver and plug it into the Jack - Chris

@@northsideservicecompany3567 my unit actually does not have the hole in the bottom of the frame with a jack it has as tape player so will this method still work and if so do you have a link directly to your kit to add it internally ?

@@vipjeffvegas Both of the NuTone 2542's I have here in the shop, have holes in the bottom edge of the faceplates to access the internal RCA Jack on the chassis - It doesn't really matter, when you add the External Audio Jack everything will be inside the Master Station. The built-in Cassette Player can be used with the Selector Swicth in the Tape position - The built-in Audio Jack is also active when the Selector Switch is in the Tape position - Chris

@@northsideservicecompany3567 bingo! Then I can just use the RCA *output* cable from the cassette player to plug in the Bluetooth adapter? Also I want to replace the speakers for the master station they are 16 ohm 8" I can't read any of that other numbers on it do you have link for good replacement speakers I want to loudest I can put without frying the internal amplifier I can find now spec sheets telling me specs on internally amplifier or speakers.

@@vipjeffvegas The NuTone Model 2542 is designed and use only 45-ohm Speaker Cones - Using any lower impedence speaker cone will over load the amplifier and it will go POOF - Especially if you factor in that your System is about 55 years old - Chris

Hi robert: Yes, we still repair the NuTone IM4006 ( I have 1 in the shop to rebuild this week) It is best if you contact directly - Chris nscompany@msn.com

Hi larry: Yes, however the WIFI Camera must have a setting for the "durartion time" inwhich the relay stays energized - you need 2 - 3 seconds of "on" time because of how the Chime operates - Chris

Hi gdi9320: You could look for LED's that have a color temperature in 3000K range (warmer) which would be more like the original lamps - Chris

Hi flydollar - Thanks for the kind words - Chris

Hi zn1: They are 68 ohm - 2 Watt Wire-Wound Resistors - Chris

Hi michael: Buy 1 what??? - A Relay Board?? - Yes, you can contact us directly - Chris nscompany@msn.com

Hi scott: The 2-wires that are connected to the pushbutton will not show any voltage becasue they are only 1/2 of the circuit that powers the doorbell. If you measured between the incomming wire to the pushbutton and the "trans" wire on the doorbell - you would find that you have your 22 volts. BTW - 22 volts is hight for a 16 volt transformer - Chris

@@northsideservicecompany3567 thanks for your help since I’m a beginner at this but I’ve watched alot of videos on this subject. are you saying that the measurement im reading at the chime and at the doorbell are as expected? From all of the other videos I watched, they all show that the two wires at the doorbell Measure the 22 volts. And at the chime, it would measure 0 volts, unless I press the doorbell, then it would measure the 22 volts. And that makes sense to me

@@scottsheck You're mixing your questions and results together -- which makes it really difficult to understand what you want / need to know What is the actualy "Problem" that you are tyrying to solve??? - Chris

@@northsideservicecompany3567oh good point. So my doorbell used to chime, but one day it just stopped working after I installed a doorbell camera. So I removed the camera and went back to the standard push button but now the simple push button doorbell no longer rings the chime. The connections are fine, I triple checked them all.

@@scottsheck There are 2 likely possible problems - 1. The Camera damaged the Chime - 2. When you rermoved the Camera the wiring to the Chime was altered and is now wrong. Also, it could be both things. . . When you installed the Camera, did you replace the original Transformer with a different Transformer? Can you move the Plunger in the Chime with your finger? Push the Plunger down and let the Spring make it pop back up There should only be voltage at the Chime when the Pushbutton is pressed - Chris

Hi Andrew: Here's some background that needs to be understood: In a doorbell circuit when the pushbtoon doesn't have a light, the pushbutton is a simple swicth, when the pushbutton is pressed, the contact are closed and power flows through the pushbutton to the coil in the Chime. When you add an incandescenet bulb into the pushbutton, you adding a "resistor" into the circuit (the filiment of the bulb is a resistance wire) this added resistance allows just a little bit of current to flow, which causes the bulb to glow, but is not enough to effect the coil in the Chime. Now for your question: I don't know what your mean by a 'smart button' - If there's some new, addtional device added to the basic doorbell circuit - that requires constant power - it is likely that more wiring will need to be added - Chris

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 RUclips responce Chris

@@northsideservicecompany3567 Thanks for replying Chris and thanks for the super informative video. I have the IM-3303 with the IS-69 door speaker and looking to install the Nest doorbell 2nd gen (wired). I've already located the DOOR SPKR terminals behind the IM-3303. In one video I watched they connected the 2 speaker wires to one of the 2 transformers behind their intercom system (so one transformer has 4 wires connected to it). Is this not advisable? Also, I actually have unused wires behind the door speaker, a set of 2-pair telephone wires. I prefer to use them if I can find the other end behind the IM-3303 but so far I do not see them, I'll need to get into the attic to see if the other end was dropped where the IM-3303 is installed. Otherwise I'll just reuse the speaker wires for powering the Nest doorbell.

@@jackogle5913 Sounds good - Chris

Hi Turbocharged.Jet: M&S has historically had switch problems since the 1980's (my opinion based on what I see all the time) Music & Sound became part of Broan (Nortek) in the 1990's - Last year M&S was sold off with many other divisions to a company called Nice North America - an Italian multinational company - Nice has done an excellant job in burying the M&S Brand, which now doesn't make any products at all. I think that M&S was part of a package of companies and as you know, sometimes you have to take the "bad" with the "good" Perhaps, one day there will be M&S products again, however I doubt they will have any real connection to previous products or designs. If you DMC3-4 needs to have the "Talk - Listen" swicthes replaced, it would be a good time to have the tactile switches and display LED's replaced at the same time - Chris

HI Tony: It certainly is beautiful sounding - Chris

Hii SonnySky7: When people tell me that "they want to remove it" I'm fairly sure they are just thinking about the Master Station and not the rest of the System. To actually remove a System - completley - you must remove all of the Remote Stations, both inside and Patio's plus the Door Station. If your System inlcudes a built-in Door Chime feature, you must figure out what you're going to do for a doorbell. The problem with leaving rements of the Syetem thourghout the house is that you now have a incomplete, non-working System. You may choose to sell the house some day and this could cause issues with buyers The cost to completely remove and entire System is not trivial, I had a customer last year start this exact converstation with me and the final cost to remove his System was around $850.00, which covered the equipment removal, wall patching and room painting. It is often best to hire someone with experience, since there's more to taking a System apart then you may think - Chris

Hi findable: Glad to know that the Video helped you - Chris

Hi vahany: Thanks - Chris

Hi dontchawishyounew: It sound like your M&S 228-C is very old and tired - You can contact us directly about having it rebuilt - Chris nscompany@msn.com

Hi carmen: You must live in an area with especially strong radio sigmals to receive AM without a connected antenna - Chris

Hi lzbth: There are fewer and fewer compnaies and people who work on NuTone Intercom Systems than ever before. What level of person you need depends on what Systems you have and what the problems with it are - You can conatct us directly about the problems, we Do Not have a "data base" of companies, however many times the problems can be delt with by us - Chris nscompany@msn.com

Hi Stewie: Well Done of fixing your IM4006 - The typical life span of an IM4006 begins when it is first installed and usually it will be 25 years +/- before it requires any amount of refurbishment (very long-lasting, I think) Since yours seems to be used mostly as a radio, having a master power swicth is fine - For complete Systems, which inlcude use for the Intercom and Chime, turning the Syetm off is not usually practicle - Chris

Hi myfavoriteddrumgear: I would suspect the 1 of the 2 very small wires that comes from the #1 Solenoid have broken loose from where it was solder to the circuit board. It is also important to make sure that the #1 Plunger moves freely inside the Solenoid and that the Spring is inplace. Lastly, it is possible that 1 of the wipers on the Contact Rotor is missing/broken off or misaligned (this is the least likley cause for the problem) - Chris

Hiu Michael: The 2 most common causes for the problem you describe are: 1 - An improper reboot after a power outage or 2 - Damage from a power surge or lightening strike. The Only Thing you can do is try performing a Reset on the Master Station - This Video show how to do the Reset: ruclips.net/video/hJ7hSia0d7A/видео.html If your IM3303 has lightening damage, it is not a do-it-yourself repair. You can contact us direlty is the Reset doesn't solve the problem - Chris nscompany@msn.com

Hi emmanuela: The Antenna should be run up to the attic (or as high as it is possible) then the arms on the antenna should be spread out and fastened to the rafters - Moving the arms of the antenna for best reeption is always a good idea - Chris

Hi enidm.pintado8816: muchas gracias - Chris

Hola Chris!! Tengo el modelo IMA 3303, El mismo problema que explica en tu video. Hoy hice todo tal y como lo explicas. Solo logré que se escuchara el radio con mucha interferencia, no logré escuchar el intercom, ni la campana, sin embargo el circuito se activa. Que será?

Hi BasedAndBasic: It's always encourging to have a customer who really appreciates the equipment he has and wants to take care of it - Chris

Hi robert: The foam cushions are there to reduce any noise that is made when the plungers are pushed back into the solenoids. This is a less issue on modern Chiem Bases with plastic solenoid caps. - Chris

Hi RBR: First, you need to understand that the IM3003 only has "Hands-Free Reply to the Master Station" - This means that when an Intercom Call is initiated from the Master Station - to a Remote Station - The reply from the Remote will be Hands-Free back to the Master - There is No Hands-Free Reply in any other circumstances. To have the Hands-Free Reply work as well as it can - the adjustments on the Syetms Must Be Setup Correctly - All of the Volume Controsl (everywhere) Must Be set to Maximum - The Program Volume on the IM3003 needs to be set to provide a "comfortable" listening level for the Radio - All of the Room-Control Swicthes need to be set to "Radio/Intercom" Finally - There isn't "just-one" componet that makes the Hands-Free Reply work. Think of it as a chain of componets that intergal to the Intercom-Control design, which is spread across 2 boards. Also, you have to conside the age of the IM3003 ( between 31 & 40 years old) circuits often do not work correctly simply due to their overall aging - In these cases, a complete rebuild is in order Chris

Hi Billy: Does your IM3303 have an Antenna connected to it? The Antenna lead is a Flat Twin-Lead Cable that's a milky-white color. On the end of the lead there's a white colored block-connector that slips down over the Antenna Pins on the main circuit board (next to the shiny chrome Tuner Box) The other possible issues can be cold solder joints in the Tuner cirucit (uncommon) or the alignment of the Tuner has drifted and your finger adds capacitance which helps-out some. Try touching the circuit board with a non-conductive plastic tool (no metal) and see what happens - Chris

Hi charles: Thanks! - Chris

@@northsideservicecompany3567 Thank you for your information, maybe that intercom is rather old. From Spain my country there're intercoms rather different, maybe they're more similar a telephone and in this link you have a intercom old with this style [ cloud10.todocoleccion.online/vintage/tc/2014/11/02/16/46004050.jpg ] even older than this intercom of your video, this intercom is about the 70s and it's a Golmar intercom, but in Spain there're intercoms similar to the american intercoms too, like this Fermax Fonoporta intercom [ upload.wikimedia.org/wikipedia/commons/8/84/Fonoporta_fermax.png ] even older than this intercom of this video about the 70s too.

Hi andy: The Brass Tubes do tend to crack over time - moving the cracks facing away from the plungers will help the sound and adjusting the "volume" (how hard the plngers strike the tubes) helps also - Chris
