Everyone knows you should replace your smoke detector batteries once a year but did you know smoke detectors expire after 10 years? If your home is more than 10 years old, you need to check to see if yours have been replaced. This video guides you step by step through the process of replacing your old, expired detectors with new ones. I suggest you go ahead and upgrade to units that also detect the silent killer, carbon monoxide. All materials used in this video can be purchased using the links below.

Welcome back guys, it's the tightwad and today I'm going to be replacing my
smoke detector with a new
Smoke and carbon monoxide alarm and the reason why I'm replacing it is because my existing
Smoke detector is expired. Yes, they do expire
so to determine if your
Smoke detector is expired
You can remove it from the ceiling by twisting counterclockwise
Mine has a little squeeze clip
I squeeze in on each side and removes this whole piece from the back of the smoke detector
So once you get your smoke detector removed, you should see a date if the contractor installed them mine says September 4th
2008 is when it was installed and right beside it. You see it says replace in 10 years
So if your home is more than 10 years old, you probably need to go ahead and replace your smoke detectors
You may get lucky and this clip may match the new smoke detector you bought if it does simply plug this in
But mine has a different type of wired connection. So I'm gonna have to replace this little tail
so before we move any further, we're going to disconnect the power by going to the breaker box and
Finding the one for this area of the house and turning it off and then we'll verify that the power is off with our voltage meter
Mounting brackets typically just have two screws holding them on
And they can be removed with just a common screwdriver
Mine, my particular ones are Phillips head, which is pretty normal
I'm gonna loosen the screws just a little bit
With my screws loosened
I should be able to turn the bracket so that the screws match up with the mounting bracket holes and this whole thing
Should come right off
Exposing all of the wires up in the junction box
so I can now pull all these wires down so that I can work with them a little easier and
We have three wires in my house, I have the white wire, which is the common or neutral
We have the black which is the hot wire
That's where the electricity is flowing and then we have the red and the red wires are how the different smoke detectors in the house
Communicate with each other because when one is tripped
They all start going off so that everyone can hear that there's an issue going on
So I have two tails coming down from the ceiling and then they're connecting in with the tail on
My wiring unit for my smoke detector
So right now I want to use my multimeter to check and see if I still have power at this outlet
I've turned off all the power upstairs because it did not indicate which one of
My breakers ran to the hallway where I'm currently working
so to be safe, I turned off all the upstairs power, but I still want to test using my multimeter and
Anytime you're testing inside the house, that's AC volts and I'm gonna go to 200 AC volts
You need to be above 120. So any setting above 120 will work. So I have it set to
200 AC volts
so I'm going to unscrew the wire nuts carefully from the white to expose the wires and
The same from the black making sure they don't touch each other and then I will touch
one lead to each of these wires and
Ensure that I still have a zero reading on my multimeter
So I know the power is off now and it is safe to work on this outlet
So now that I've ensured the power is off
I'm gonna go ahead and remove the last wire nut from the communication line
And then I'm gonna untwist all of my pairs to remove this old tail
It's now as simple as matching your colors. So I'm gonna go
White to white and install my wire nut black to black
You want to wrap the wires?
clockwise
Otherwise, the wire nut will just unwrap them since you tighten the wire nut clockwise as well
And then my last one in this case mine is orange and the wires and the ceiling are
Red, but your colored wire is your communication line
I'm gonna screw the wire nut down on those and I can tuck all three of those connections
Back up into the junction box. So the next step is to install our mounting bracket
Your new mounting bracket should fit right where the old one was
So hopefully the screws still line up and hopefully it's the same size. So you don't have to do any painting
If you do have to paint I recommend you paint prior to
Installing the new mounting bracket so that you don't have to take it back down to paint around it
Make sure the screws are snug, but don't screw them in so hard that they break the plastic
Just give it a little twist and see if it spins
And now we're ready to install our unit
The back of my new alarms actually has a place to write the date that they were installed
I think the month and the year is sufficient
But do this so that the next tenant or homeowner
Will know when it's time or if the smoke detectors have been replaced within the last 10 years
So now I just plug it in
To the harness we installed you should hear it click or snap into place
Push your wires up inside if needed
Rotate it
counterclockwise
Until it stops moving if your new smoke detector comes with this battery guard
Leave it in until you've got everything connected
So that when you do your testing, you know that it's running on the power from the home and not the power from the battery
So it's always a good idea to test it while this is still inserted
And once you know, it's fully functioning
Then you can pull that tab and activate the battery backup system for your smoke detector
With the new smoke detector installed and our battery tab still in place
I'm gonna push the button to test that series of alarms
It lets me know that this smoke detector is installed properly and hardwired to my system
So now I can remove this battery lock
From the device which activates the battery and the chirping should go away
this alarm set off all the other alarms in the house and
Then it gave a series of four beeps a pause and four more beats to let me know that we're good to go
Each type of alarm has its own series of beeps
So make sure you read your installation manual to see what kind of codes you're shitting it
