How to wire smoke detectors - smoke detector interconnection - The Electrical Guide 

You get a new subscriber. I don’t even need to look at other vids to know I’ll appreciate them. Thank you for this.

I just found the perfect virtual assistant voice.

Thank you for simply taking the time to fully explain how to wire up my smoke detectors. 👍👍. Two thumbs up.

Man you are the best I’m so glad how you made it very simple Thank you so much 😊

Thank you for this!! YT isn’t always the treasure trove of information. There’s NO videos really on this. A lot of meandering talking about things that don’t matter!

Thank you for posting this, it is very informative and gave me the confidence to do this myself.

Very good job of clearly explaining & throughly demonstrating.

Perfect and to the point vid. Thank you. This vid is a great help.

perfect, exactly the info I needed. Thank you!

Very well and clear explained

Informative to the point 👍 Thank you

Thank you for the demonstration.

Thank you, I really appreciate the video.

Will have to try your pre-wrap your stranded wire method. Stranded wire is always a PITA

Very detailed video. Learned a lot. Thank you.

Thank you so much for the great information! For someone who has never worked with electrical items before, this video helped me out a lot! I was able to install my 6 smoke detectors, wiring and detectors, without problems! Thanks again!

Great video, thanks.

Your handling of wire is almost magical...

Great video. Thank you.

Thank you! I’m a noob that’s brave/dumb enough to attempt a panel move and full rewire solo-ish. I figured this was how it worked but any potential mistake would have been multiplied by 6. Cheers for the piece of mind!

Thank you for sharing 👍👍 Clear Explanation and Easy to Understand

Can you do a separate video to show how you spin your pliers around like you did early in the video? ;) You must be a drummer; that was smooth!

Thanks for the great video

Thanks for the great video.

Thank you this happened to be the first video I saw and it was the same smoke detectors so everything was perfect

This is video is perfect for DIYers like me...Thank you so much!!!! (I am a subscriber now...)

Very helpful video, Thank you so much.

Well done! Thanks!

Thanks a lot very organized and neat work

Simple, to the point. Sounds like Mel Gibson

Good video Thank you

Agreed and an excellent video.

Thank you good video

Am I right in assuming that if you're only installing one alarm you only connect the black and white and disregard the red tucking it up inside?

Great Video thank you

Thanks great info 🙂🙂🙂🙂🙂🙂🙂🙂

Good tutorial- thank you

Perfect thank you explained very well

Great video

Great job brother

Good presentation....

Good video

Thank you sir

Very nice

New Sub here. Thanks for the content⚡

Thankyou.

Great video! But dammit I gotta go buy 14-3 wire now to link them together. Lol

Your idea of a lighting circuit indicating a problem is good, but is not code everywhere. In my area the detectors must be on a separate circuit. Your install instructions were excellent!

I did 5 of these Smoke/CO2 detectors, only thing, I continued the 14/3 to the panel box. How do I wire in - what happens with red? Or, do I have to use 14/2 to the box? Love the videos! Great to see them and confirm I'm doing it right!! Thanks

That is wonderful that you are helping people so I asked you my smoke detector has wires going to it I have sprayed it with air and it's still going off I held it down for 20 seconds it's still going off I have been dealing with this for over a month please tell me what else I can do

First off, thanks for your informative and clear video. If you have any insights on wiring described below, I'd appreciate any input/feedback/thoughts. BACKGROUND: I replaced 3 hardwired (ionization- style) smoke detectors with combination smoke/CO detectors (one per floor). Now I want to replace a very old photoelectric-style detector on our bedroom level that is located less than 2 feet from the replaced ionization-style detector. Unfortunately, the manufacturer of the photoelectric detector no longer exists. Replacing the ionization detectors was easy, as they had a snap-in adapter on the back with the typical red, white and black wires. The photoelectric one I want to replace, however, is connected to 6 wires (red, black, white, green, blue, and yellow) with the wires poking through a very small hole in the ceiling. The 6 wires then connect to 4 screws inside the detector (screws are labeled 1-4): yellow & white to #4, blue & green to #3, black to #2 and red to # 1). I'm not sure why there are extra wires and what they might connect to (might it be for a security system)? Any idea on what is needed to hardwire a new detector in this 6-wired location and what these 6 wires represent? If needed I'll hire an electrician, but have completed simple electric work (e.g., replacing ceiling lights, etc.) and, if straightforward, would prefer to do myself.

Amazing, I was confused , about the homerun 12/3 or 12/2 So 12/2 going to first box detector and 12/3 jumps between the other boxes

Great info thanks. How could you incorporate temporary silencers?

thanks

Could you come to my duplex, and show us how you would do it by installing it into my attic and then running it to the breaker box. Give me a complete picture you know.

Thanks អរគុណ❤

Good video….. I want to add a Kidie heat detector into my garage. The main house has all the detectors already connected. My problem is that my flat roof house has no access to the attic. How can I connect the red wire so that all detectors will work correctly? The main electric panel is in the garage also, so I can access the fire alarm loop in the main box.

Thanks! I always want to know how they do this installations. I do the low voltage Fire alarm systems installation and program but always customer ask me how this works and finally I found a video to explain me how they are wired. Just need to know now hot they connect these devices to a 120 VAC bell or/and 120 VAC strobes...

Deep voice

I noticed you used octagon boxes. I am adding some Gentex interconnected smoke alarms to an existing home (old work installation) and was going to use 3x2 switch boxes. Can the octagons be mounted in an old work style? Do you generally prefer them over switch boxes?

What do you do with single ground wire that is not connected to anything with a plastic box?

Do all alarms have to be fed from the same circuit? Example: the smoke detector I have outside my bedroom is already powered. I am finishing wiring my garage (sub panel fed from that same main panel) but was going to run a circuit for them, and then just send a signal wire up to the alarm outside the bedroom. It seems like that may cause some sort of issue with two different circuits powering. I figured the interconnect wires would be a stranded low voltage but it appears like it is a fairly heavy gauge wire...?

Great explanation! I'm considering wiring those in an old home which currently uses battery-powered detectors only. Does the code require a dedicated branch circuit for the detectors, or can I j-box from an existing circuit?

Do you know how many of these detectors can be run in a daisy chain. I am thinking of tapping into the power from one of the lights in a room, do I need an independent circuit from the panel, or can I tap the light box. I have seven to link in a house.

I find this helpful except that this is the easy part. Bonding those boxes and running the wire correctly (conduit if necessary Etc) is what I’m looking for. This should be a relatively easy job and an upgrade I should be able to do myself. I just want to ensure I’m doing it all correctly

How do you put one in between two detectors? Do you need to run a wire from the last one or you can just attach the wires to the previous one.

My old wiring is only black and white, no orange wire available, will this newer unit still work with out the orange wire

I have 3 smoke detectors and 2 smoke/CO that are all supposed to be interconnected. Two smoke/CO detectors are connected but the smokes are not. All have interconnecting red wires. They are now all Kidde but same results with Kidde and X-Sense mixed.

Just wonder where is the ground wire for the last smoke detector go if using the plastic box?

Is it safe to use Wagos to connect the wires? I always have terrible luck working with the stranded wires.

So the old tenants here at my house left the wires sticking out of the wall they are black, white and yellow. I'm assuming the yellow is the interconnect? So if I buy identical smoke detectors will I splice the yellow and red?

Hi. Can someone help me?? This is great video!! But what size breaker do we use? 15amp?? Thank very much!!

I know I don't have to but can I just put the smoke detectors on their own breaker and can I use 12/2 and 12/3 since I already have it on hand?

You said the 14/2 was feed, is that same as "line"?

If i don't want all of my smoke detectors to go off simultaneously do i not connect the red wores. Thank you

I have red, white, and black on the old Not-working any more smoke alarms. But the plug-ins to new smoke alarms aren't the same as the old plug-ins to old smoke alarms. Can I wire with caps the new plug-ins, so I can use the new plug-ins for the new smoke alarms? Of course, I will test the new alarms afterward. Thanks for any help.

hi i am wondering as i will add a smoke detectors to the other smoke detectors, will it be ok to add a wiring to the 3 black, 3 white and 3 red plus the ground, the wiring will be 4 each color? thank you

Thank you. I have access to the first detector where the power comes in and a 3 wire goes to the next detector in the home if I wanted to add another one from this detector is it true I add another three wire here going to the new detector?

Question if I may. I have preexisting smoke detectors in 3 bedrooms a fourth room is now considered a bedroom. How do I add a detector into the existing run?

What if the box is plastic. Do I have to put a ground wire to anything?

On a 3 level house do all the smokes go on one circuit? Run the smokes first and then after the last smoke go into a switch and out to some lights?

can I cut down the bonding wire in the last smoke detector in my house? in video 5:57

I need to eliminate one hardwired interconnected smoke detector due to wood stove install too close. Will put a battery smoke detector farther away. My question is can we remove the pigtail and put wire nuts on the hot wires and close up the hole will it affect the other detectors in the house that it was connected with? Can't find an answer anywhere. Thanks

Why does the ground wire need to be bonded to the box?

Very clear, thorough and to the point. However, by simulating the install with the electrical box away from the ceiling, you miss the awkwardness that’s always involved.

Can u please tell me the sizes of each wire and capacity of smoke detector?

Great Video. What hapens with a home retrofit where the fire alarms are not on the same circuits and not on the same floors. Can I just run a singe wire from one fire alarm to the other.

What voltage is the signal wire carry is there a normally open contact when one goes off it closes the contact sending 120v through the red wire im just curious

Question. Hoping someone can help me as apparently Kidde’s support has disappeared during the pandemic. I had three interconnected hardwired smoke/co2 alarms. All three reached the end of their useful lives in the past couple months. I had two stand alone nest alarms lying around so I mounted those, leaving the kidde quick interconnects in the ceiling box. For the third alarm, I installed an identical kidde alarm and hardwired it into the electrical system using the existing three wire harness. I then read the instructions (🙄) and it said don’t use the red wire, which carries the 9 volt signal to the other hardwired alarms. Can someone tell me if it is necessary to disconnect the red wire? My red wire goes to the other two kidde harnesses which aren’t being used. I’d prefer to leave everything connected as when the two battery nests reach their end of life, I’d like to go back to using three kiddes and have them be interconnected. Not a big deal to disconnect the red wire but I don’t understand why I have to. Can someone explain what the issue is in my situation?

Where was this video when my landlord was saving money by using fake smoke detectors?

So what do you do inside the main panel with the red and black? Do they land on a two pole breaker?

Can you remove 1 detector from the series without disabling all of those in the series? I want to replace 1 with a battery operated detector.

changed mine now bedroom does not beep when testing

So your first home run coming from the panel needs to be 14/2 and everything there after needs to be 14/3? Great video

And also the smoke detectors that I have right now there are not wired so how do I do?

so the red one is just data?

If I don’t have hardwired ones, I’d have to pretty much get an electrician to install hardwired ones right?

👍

How many detectors/ rooms can I put on one line ?

What box is that? Is that junction box?
