How to Install Hard Wired Smoke Detector - Easy Installation First Alert Smoke Detector Model 9120B

[@ShereeBoley]

Great video-really appreciated the step by step to switch out the First Alert detector, especially the detail on connecting the wires at the end. We ended up making several trips up/downstairs to get all the tools we needed: extension cord to plug in a light, 2 different screwdrivers & plyers -couldn't get the caps off the original wiring. Don't think we could have handled this without your video! Thanks!

Great video. This helped alot. I bought same brand smoke alarms from Costco and installed them using the very last method.

[@MimisFoodieLife]

Your instructions were very clear. I think I will try to do it myself.

Thank you!!! I needed exactly this video - especially the end with the rewiring part! Really appreciate this!

Thank you so much for this video! I'll be trying to replace and rewire 6 of these this week. I'll come back to let you know how I do :)

THANK YOU!! Best Video on this smoke detector!! I've watch 3 other videos and the other ones, Ignored the Orange wire. A++

[@victoriamaile]

Thank you for your video. Watched a few wasn’t helpful, but yours was right on point. 👌🏽😅

I suggest looking at a video showing the RIGHT way to connect wire nuts if you need to do that step. Also, the video does not explain how the red wire is used, and why it has a cap on it. HINT: When used, the red wires allow all the smoke detectors in the house to communicate with each other in the event any alarm goes off.

Thanks for the schooling. I didn't know they come with adaptors, great!

[@johndbender5250]

uh, yeah...that little cap on the ORANGE wire does not just pull off like it does in the video. I had to cut it off,,,,PIA

[@alexg5793]

Ahaha same here

[@dannygreen592]

How do you remove the mounting bracket?? It doe snot just come off like in the video!

[@traceym5631]

what does it mean if the red light is flashing but the green power lightest degree

[@TheRenderQ]

A green light usually means the unit is powered up. The red LED indicator can have various meanings depending on the sequence of blinks. You’d have to look at the label on the detector itself or consult the manual. It can also tell you which detector was activated most recently.

Thank you. I follow your video.

[@alexg5793]

Grate video, God bless you sir

[@gaberlv]

Hey thanks! Great video.

If you like me bought the dual package with the 2 in 1 CO alarm also, the adaptor is only packaged with one side of the alarm, so make sure you unpackaged both frustration packages and the adapters are on the left alarm side. I almost thought I don't have that adaptor at all. Also, mine has a 9V battery back up with a battery door locked as "DEFAULT" and was taped behind the factory label and a transparent film blocking the connection. It instructed to pull the transparent film off before use, but it's stuck in there so hard that you have to UNLOCK the stupid battery lock, open up the battery door and still struggle to pull that piece of transparent plastic out. What a stupid design and instructions. They should have highlighted that the door lock is LOCKED by default. Anyways.

I just bought a twin pack at Costco, pretty good price. After I replace my two existing Kidde combo units, will the new FA units talk to each other, by that I'm asking if one detector goes off, will the other combo unit fire off as well? I would think that's what the red wire is all about? Another question: I have 3 other regular smoke-only Kidde units, will all 5 still fire off if any one of the 5 detectors goes into alarm?

[@MarvinLindroth]

The orange wire tip did not slip off. I had to clip it off.

[@tesfe]

Thats my concern. Did cutting the orange wire work?

[@russvyas7617]

What is that red/orange wire for?

[@ofcbob6391]

It connects one smoke to another: if any one of them goes into ALARM, all your detectors will fire off so there are plenty of BEEPS all over the house...@@russvyas7617

[@bruh3120]

​@@russvyas7617its to interconnect other smoke alarns together

[@helenachase5627]

The battery set up for this alarm is c*** pure c***

Smoke alarms (depending on the type) last 10 years. Not seven
