Can I replace my 4120B smoke detectoes with 7110B using the same mounting plate and hardwire plug?

Shirley - with 95% certainty I would say yes on the hard wire plug and no on the mounting plate. However, the new mounting plate will likely easily replace the existing mounting plate? I recently replaced my 4120Bs with 7010Bs and the hardwire was exactly the same. The mounting plate was two screws that I loosened, twisted off the old mounting plate, twisted on the new and tightened. It took less than a few minutes to change the mounting plate and less that 5 minutes to change the entire smoke detector. I used the 7010B and you mention the 7110B but I presume they are approximately the same.

Don't know. I don't use 'hardwire plug', only battery. Mounting plate itself, not a problem. (I replaced older ionization alarm with a photoelectric, in part because the photoelectrics are supposedly less sensitive to smoke .. fewer false alarms. But am finding that the newer is just as sensitive to kitchen cooking smoke).

I'm also about 95% sure you can-but my old one was so annoying I yanked it out of the ceiling-which was good, I had to replace the plate which had burn marks on it, I guess a fire was waiting to happen.. my nephew came to reconnect the wires--but the rest was easy..I so love the 7110..

Hello. I don't remember the model of my old smoke detectors but 4120B sounds familiar. I had to remove the old mounting plate but that was as simple as loosening the two retaining screws, removing the old mounting plate, installing the new mounting plate and tightening the two screws. The hardwire plug was identical. I did eight detectors in 30 minutes and that includes setting up a very tall ladder. Good luck.

Hi Susan, apologies for not replying sooner. The Rockler Guide Bushing Router Plate will not fit the B&D; 7616. The holes on the B&D; do not align with any of the hole patterns on the plate. Regards

J. Hur,This will not be a problem. I have 3 different models connected to my hard wired/ plus battery system. A total of 6. Some with different sensitivity than others. Since they are all made by First Alert / BRK. I haven't had any problem with them for over 21 years now. Plus they all come with a wiring harmess pigtail, should you damage your old one . I have noticed some of the new replacment detectors have replaced the 9-volt battery with two AA . To be honest, I think it's better . I hope this helps you.Ronnie

I found that the connector on the wires was a little difficult to seat in the receptacle on the smoke alarm. You might look at the connector to be sure that the pins didn't bend. There is a "key" on the connector and the receptacle so that it should only mate one way.Also, did you put backup batteries in the alarm?Did the green light work in the old alarm?

Adam, These moduals have been revised 2 different times since being introduced. On this model, the 3 wires have to be spliced. The thinner control wire on the Olds was a different color (blue vs. brown), but worked just fine. I would say that if your T/B has a modual with aluminum blades for a heat sink and the mounting tabs look to be the same, it be worth trying.. God Luck, Bob ...

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

Those sensors will work on the older board. they wire the same but do not mount the same. you will need 1/4" carriage bolts in order to mount them correctly

I replaced a Kidde 1275. I don't know what lifesaver is. I was able to install the smoke detecter to the old mount and it fit exactly as the old one did. Seems to be working fine.

You'll have to add your own. I soldered a diode inline with one of the output wires.

I answered this several weeks ago, and I just checked the site and for some reason Amazon didn't post it; their bad! All of my smoke alarms were hard wired as per code. But if the 9v back up battery in one died, all of the alarms went off; I was up all night one night. Anyway, my old ones were not Kidde, but the Kidde replacements fit perfectly.Go to: www.kidde.com and find their Customer Support 800 #. They were very helpful when I called them. Good luck, and I am sorry my first answer was not posted; I have no idea what happened. navydoc

It can replace E127765 Mod TA306 120VAC. Wife bought this sensor , and we just installed it. I figure I share my finding.

I matched my unit up by the dimensions as close as I could. Even then I wound up bolting a new solid plate in place of my old one and then mounting the new step to the new plate. I also had to run two new wires, but it was just as the directions listed. I hope this helps.

3107612.008 has been 'discontinued' but the Dometic 3106995.032 would be the replacement. A quick 6 wire for wire swap & done! The units look the same on the outside but different inside - not an issue - it works just the same.

Hi fturbo, I'm looking at the package that I still have for my Model 7110 and it reads "...replacement No. RB10T5 (or F10T5)"

Yes, you will have use the new base but the screw holes are in the exact same place. I just replace my 4210B's.

Unfortunately I gave my old one to hazmat, so I don't know for sure, but I would very much expect that the plates are the same on those two models. The XTR has a tamper resistant feature in the mounting plate, but I can't see how that would affect the mounting and you don't have to activate it anyway. Sorry I can't be more helpful.

Brand makes no difference within a hardwired 120VAC circuit, when replacing another brand with a BRK model the pigtail (or wires that come with the 120VAC model may have to be changed due to the method of connection to the detector.
