Customer Questions & Answers

I currently have 6 BRK model 4120 B smoke alarms with a 3 pin connector. Will model # 9120 B6CP interchange with those?

Asked by: Curt
I have the 4120s too, and the product image that shows the back of the mounting plate also shows the connection, which looks like the same connector to me.

I have Model 4120B

Ours are chirping,even with the new batteries. Will this 6-pk work?
Asked by: Con

This replaces the 4919? Do I need to replace the mounting also? Is the wire connection still the same as 4919? Thanks

Only thing I had to change were the trim rings which were slightly larger than the older ones, and that was a 2 screw loosen and tighten operation. Basically it was a plug and play replacement. If they perform like the old units there should be no issues.

Rated 5 out of 5 by from Easy as can be I don't think you'll believe me when I tell you this was the easiest fix to a home inspection I've ever done. I wasn't aware you're supposed to replace your smoke detectors every ten years. If you buy these, you'll wish it was more often! It took me longer to move the ladder to each spot than to switch out the units. I had to replace four units and it took 20 minutes. So simple, rotate and unplug old base, loosen the two screws to cradle and rotate off the cradle. Remove new base from new cradle, slip new cradle into place and tighten screws. Plug in new base, rotate onto new cradle. Test. Wow, took longer to write this than to replace a unit. The worst part of this whole installation was the noise swapping out alarms.

Installed easily but , though I expected the base wouldn't need to be used as the old unit was also a BRL, the base was different requiring loosening the mounting screws and replacing the old base with the new....No big deal. 5 minutes per unit.

Rated 5 out of 5 by from Great Value This set is a terrific value. Not sure why HD only offers this online and not avail. in stores. Would have saved time if I could have picked up at local HD.

Rated 5 out of 5 by from Great Replacement Smoke Detectors My house is 20 years old with direct wire smoke detectors. The old smoke detectors had a direct wire harness that easily plugged into the back of the detector. I pulled the old detector and got the manufacturer's name (BRK) off the back and researched it on the internet. Fortunately Home Depot carries them in this 6-pack. I ordered the 6-pack on line and received them in 3-4 days. The installation is a breeze - just replace the mounting bracket on the ceiling and the old harness plugged right into the back of the new detector. I replaced all six detectors in my house in about 30 minutes time at a cost of about $12 each. The 6-pack also comes with the back up batteries and the pig tail wiring harnesses so you can just wire nut them into your existing wiring if you don't have the same harness already in place. Great Price and easy install... what more could you want? I highly recommend this product!
