This was purchased to replace the old smoke alarm which was a BRK made by First Alert and recommended by the customer service from BRK. The previous smoke alarm was 9 yrs. old and started to give false alarms ceiling mounted. Customer service said that it was only guaranteed for only 5 yrs. well over due. It was easy to install and the hard wire was the same as the old model; nothing to change. I just removed the old bracket (two screws) and installed the new one. Plugged it in and was ready to go. I have to mention that the battery back up is easy to replace but when installing it REVERSE the battery when you see it in the package. The instructions doesn't show or explain how the battery is installed. If the alarm chirps the BATTERY IS IN WRONG! It's smaller than other models and the same size as my old one. It comes with a kit for other smoke alarms kiddie, firex and has the wiring for those models. You can't go WRONG!

We had been looking for replacement smoke detectors to change out all the old ones in the house we just bought. They were the old BRK ones that have the old style 3-prong connection. I had purchased new ones, but they didn't come with the adapters and I would have had to rewire all of the smoke detectors to get any of the new ones to work. I found these online as the only ones advertised as coming with adapters. However the actual smoke detectors as is are the connectors we needed. If we ever needed to replace these new ones with something else, we now have adapters and the pigtails that would easily convert new models to what we have. They've been up for about a week now and I haven't had any false alarms yet. So far I'm happy with them.

I was concerned about compatibility with the plug in connection to my hardwired system. Not only was this the same connector as I had for a BRK 4120SB, but the adapter kit has wire sets to convert for other manufacturers' connectors. I also learned in the process that BRK and First Alert are the same company. Complete replacement took 5 minutes -all the old parts gone and new parts installed and tested.

Customer has been confirmed to have purchased the item from Walmart.

They say in the description and specs that it will adapt to all Firex G models as listed. Then you buy it (and you can't just replace one, but have to replace ALL of your units in line) you'll find in small print in one spot it won't adapt to one specific model. No model number, just a picture of the wire harness which is nearly identicle to the one it will work with. Called the company and they know it isn't listed anywhere you'd find it easily. Nothing they will do about it, just go and rewire your entire set! Nice customer service. Truthful specs would help before I bought the group. Same thing about info on replacing just one. They only tell you that all must be replaced in the small print too! If you only try one, all of the units in your house will go off.

  • A. I would assume First Alert has taken this in consideration. I wold advise replacing the old base with the new one for esthetics.

  • A. The wall or ceiling adapter is enclosed in the package. Just remove the old one from the wall or ceiling and screw the new one in its place. If the plug adapters are different than those supplied with the new unit then simply cut the old connector and wires from the the older unit and connect them to the new unit and plug into the connector that exists in the receptacle box.

  • A. That is the model that I replaced 4919 that was 9 yrs. old. Yes! It does have a new bracket and the wiring harness is the same as the old one. This has a battery back up while the old one didn't but remember to REVERSE the position of the battery from what you see in the package and point the contacts toward the inside; they don't show or explain that in the instructions. When I installed mine it kept chirping and I couldn't understand it until I REVERSED THE BATTERY. Good Luck! I hoped this helped? Recommended by Consumer Reports!

We have several Firex FADC smoke detectors and want to replace the ones that chirp "every 30 seconds". Chirps every 60 sec mean change battery. Chirps every 30 sec mean replace detector. Has anyone used these to replace their Firex smoke detectors with 3 pin plug?

  • A. The one you are talking about is the same as the Kiddie which was of the same type but not brand as the ones I had. This First Alert comes with a few adaptor plugs. One of which is the three pin plug.

  • A. Yes. I used this model to replace a Firex. I cut the plug off the older Firex and connected it to the new unit and plugged the connectors together. Works fine. Generally the black and white wires are the ones used but, if you have the detectors in series, that is, connected to other smoke alarms then you would also use the orange to accomplish activation of another alarm in series.

  • A. My old Firex Alarms came down and I bought 3 of these and they went right in. The adapter that worked did not seem to be a perfect fit, but they are all up now for a couple of months and I can see the green light is lit and every week they have passed the test button with no issues.
