I have Model 4120B

Ours are chirping,even with the new batteries. Will this 6-pk work?
Asked by: Con
I had the same issue. I replaced the 4120 with the 9120 and everything was golden. All you need to do is remove the 4120. Loosen the two retaining screws and slide the old base off. Slide the new 9120 base on and plug in the power and twist the 9120 on the base. It took me a whole 2 minutes per detector to do the swap. No more chirping or false alarms.

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.

120-Volt Hardwire Ionization Sensor Smoke Alarm with Battery Backup (6-Pack) is rated 4.6 out of 5 by 42.

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.

Rated 5 out of 5 by from Excellent Replacement My smoke detectors were over 10 years old and would go off randomly at 2 am. I called the company and they recommended this item as a replacement. I needed 6 so I bought the contractors pack. Simple to install. I didn't even need to use the plugs that were included. Took me about 20 minutes to install six. Thrilled!

They replaced 18 year old hardwired detectors. Installation was simple. I just had to splice the new style connectors on the wiring. Purchasing the six pack was 1/3 of the cost of buying them individually.

I bought these smoke alarms to replace our existing smoke alarms that are hardwired in our home. There were simple to install and work as described. One thing I do not like about the design on these smoke alarms is that the indicator light is hard to see.

These were purchased to replace previously installed alarms that were 11 years old. The installation was extremely easy and I would recommend these if you already have similar units installed but are due for replacement.
