How to Replace a Beeping Hardwired Smoke Detector

My how to fix a chirping smoke detector post has been one of my most popular posts on this blog since I wrote it two years ago. I am glad I am not alone with the whole detector beeping and waking you with a false alarm in the middle of the night scenario.


I tried three out of the four ways to repair a beeping or chirping smoke detector except one – replace it with a new model. Turns out my smoke alarm was broken and beeped, chirped and otherwise drove us crazy and Blitzkrieg in to false alarm barking spasms for far too long.

*Enter the Condo Blues Whammy*

Of course my broken smoke alarm was in my bedroom – the only room in the house with the cathedral ceiling.

*sigh*

However it was a very easy and cheap fix to replace my broken smoke alarm with one that no longer beeps and wakes us up in the middle of the night due to a false alarm once we bought a very tall ladder.



You will need

A hardwired smoke detector (easily purchased at a home improvement store)
Screwdriver
Drill
A ladder (or if you’re me a HUGMOUSLY tall ladder)
Wire strippers
Electrical tape or electrical wing nuts or both

Warning: If you are unsure about your electrical skills please call a pro to do the job for you. I don’t want to lose any readers because you electrocute yourselves or fall off of a ladder and break something important.


Fix it

1. Shut the electricity off at the breaker to the room with the broken smoke detector. VERY IMPORTANT!

2. Remove the broken smoke alarm from ceiling mounting plate. Chances are the smoke detector will twist off of the mount plate with your hand.

Please excuse my photo quality for this tutorial. I had to choose between good photo quality and losing my balance and falling off of the ladder. I choose not to fall off of the ladder and my photo quality suffered for it. Sorry folks.

3. Unscrew the screws attaching the mounting ring to the ceiling to remove the old mounting ring from ceiling.


Yes, the plastic ring took some piant off the ceiling when I removed it. Oops.

4. Remove the electrical wing nuts and connectors from the wires in the ceiling. WARNING: Make sure the electricity is OFF to these wires or will get a nasty, possibly fatal shock. And we don’t want that now do we? Of course not.

5. Make the new connections. Follow the wiring diagram that came with your new smoke alarm. Use the wire strippers to remove the wire insulation from the tips of the wire if needed so you can twist the bare tips of wires together in order to make the connection.

Twisty and connected.

6. Wrap each connection in insulating electrical tape.


Use insulated electrical tape.

7. Screw on an electrical wing nut at each connection to ensure that the wires connect and are insulated. NOTE: Some say that you can use either electrical tape or electrical wing nuts to make and insulate two connecting wires. However, my Dad taught me to use both and since he is a stickler for doing things right and safe the first time this is the method I use too.

I reused the wingnuts from the old smoke dectector.

8. Attach the mounting ring of the new smoke detector to the ceiling by drilling pilot holes in the ceiling as needed and screwing the mounting plate to the ceiling according to the directions that came with the new smoke alarm.

You may have to drill new pilot holes for the screws to the new ceiling mounting plate.


9. Plug the smoke alarm into the ceiling plug.


Almost done!

10. Attach the smoke detector to the ceiling mounting plate according to the directions that came with your new smoke alarm. Mine was supposed to easily hand screw into the groves on new ceiling mounting plate.
The newly installed smoke dectector!

OPTIONAL: Give the new smoke detector the stink eye and mutter unprintable threats to your smoke alarm until you can coax it into place. TIP: Don’t let your dog hear you mutter unprintable threats to your smoke detector or he will make you put a dog biscuit in the swear jar for each offense and need a seven mile jog to work those treats off later. Not really recommended BTW.

10. Press the test button on the installed smoke detector to insure that it beeps and is installed properly and you’re done!
