Are these a direct replacement (form, fit, and function) for the model 41208? can I just remove the 41208 and plug the 9120 into the same base?

I had no problems by just removing old unit and plugging the new units to the base.I changed out all units and now have new electronics and wiring for complete house.Michael Arakelian

There is a wiring (pigtail) that might need changed. It is supplied in box.

I don't know about the 41208, but I bought these to replace units that were 13 years old. I was hoping for a direct replacement, but I found that the bases were slightly different, that's the bad news. But the good news is that taking off the old bases and installing the new ones was a very simple task. The electrical connection was the same so I had two new units up and operating in very short order.

The electrical connection should be fine. You may have to replace the "collar" that fits on the box and touches the ceiling, but it is provided.

The plug is the same but you still have to remove the old base and install the new base for this unit. It's real simple, though. It takes less than five minutes.

The replacement could not be easier. I think I twisted off the old unit, then unplugged the connector, plugged in the new one, twisted into the locked position. Two minutes max. I think the new 9 volt battery comes with it.

Sorry, I can't help with that. I don't know anyone with a 928. A perfect fit for a 920 though! Good Luck

I cannot tell you, as I don't know what the 4122 model looks like. If it is shaped like the Zing, then I would try them.

I used this on a 1970 Model 10965. I think the series with the 9's started in 1973. This replacement lined up perfectly, without modifications.Can't say that it will work one for one.

I have already made that substitution when my #92590 burned up. The replacement works very well.Walt Piper in Roaring Spring, PA

No the 1076 will not replace the 921. Both have different bases, one is a push and twist the 921 is a straight push in.Ron

Fred, I am sorry we are not familiar with the unit, but it is unlikely if would be a direct fit, possibly if modified... sorry. Dan CSH

Not the interchangeable one. The one that come with this model is the exact one you seen in this photo, I doubt that it can be changed though.

Yes they are based on different model numbers. Please check your owners manual for a replacement part number.

It replace these models but you have to use the adapters that come with it. AO416B2059 AO510B2389 FO510B2497Good luck.

I don't remember which model my old ones were, but the 9120B used the same wiring as my old ones. The 9120B did not use the same base or mounting bracket as my old ones, but those are easy enough to replace.

I replaced my 6128 with 6148. You need to use some pin to take out the 4 metal contacts from 6128 connector, then insert them into the corresponding sockets in 6148 (eg, insert metal part of Yellow wire from 6128 to the Y socket of 6148). It took me about 5 minutes to finish the whole job. I did the red one the last.

I found an interconnect chart from BRK brands that says that the 9120B is compatible with the 4120B. That chart can be found here: http://www.brkelectronics.com/BRK%20images/BRK%20Interconnect%20Chart-Hardwired%20Smokes,%20CO's%20&%20Heat%20Alarms.pdf It did not mention anything about requiring an adapter. It just says it's compatible. So that means that there is no guarantee the mount will be the same or that he pigtail adapter will be the same, although it could be. It simply means that the 9120B and the 4120B can communicate with each other in an interlinked fashion (one alarm sets off all alarms). I would expect that at most, you would need to change the mount and connect up the new pigtail adapter. Even if it's not "plug and play" you should be able to get it to work for you.

I don't know this FOR SURE, but logic would dictate that the manufacturer would be the place to go for this info. Perhaps even online suppliers would have accessory listings for such a replaceme...best I can do, sorry

Yes, the dimensions are the same. Also the Schmidt 888 is a direct replacement.

This replacement works with the 560 model that I have. It works with a number of models, but you would need to check.
