Rated 4 out of 5 by md55 Great dual purpose smoke detector
I bought these to replace 12 year old units. I bought both the hard wired with battery back up and battery powered only units. I much preferred these dual powered for installation and maintainability. I would have used them in all locations had I known the quality of these units at the time of purchase.

This detector was a direct replacement for my old unit and was easy to install as advertised. No more false alarms in the middle of the night! Updated styling looks great too!

Rated 5 out of 5 by rbprivate1 Excellent product at any price!
I bought these to replace old Firex detectors that I installed during construction in 2002. Your detectors need to be replaced at least every 10 years. These are a great choice.

Rated 5 out of 5 by OhGee EXCELLENT VALUE, EASY TO INSTALL
I purchased three of these to replace the old BRK 4120B detectors in my upstairs hallway and sleeping rooms. If you are doing the same, you will have to take down the old mounting bracket, as the 9120B will not fit, however it's as easy as loosening two screws and rotating the old bracket out, and putting the new one on. The wiring harness is the same, so they are literally plug-and-play.
I haven't been able to find these locally at the low price that 1000bulbs sells them for, so I will purchase another three soon, thus completing my home's smoke alarm updates.

Rated 5 out of 5 by buzzsaw Easy fix for beeping smoke detectors
This unit easily changes out from the old style dectors and come with a battery installed and ready to go. If your unit is still beeping after you install a new battery, just trade it out with one of these and you'll find peace.

Rated 5 out of 5 by GFSCHICAGO A great product at a great price
I replaced a similar product in my house with this unit. I was happy to see that the MFG. used the same adapter to the wiring in the house. It was an easy snap out the old and snap in the new. I have ordered many times from 1000bulbs and never had a problem.
