First Alert BRK ADK-12 Smoke Alarm Adapter Plug for Kidde Hardwire Smoke Alarms, Pack of 12, White/Black

I bought these to make swapping from kidde to first alert easy. They worked like a charm. My only complaint is they should have various packaging. I only needed 5 but have to buy 12.

Easy to use! Received the wrong type from what I ordered. Had the replacements the very next day. Awesome service!

I had 14 Kidde alarms to replace. It took me the same amount of time to replace the first 12 (using these adapters) as it did to replace the last two (manually changing the wiring.) So figure a 6:1 time savings, totally worth the price. Plus, when you're up on a ladder on a two story balcony, it is a lot easier and less stressful to plug in this custom-made harness one-handed than to use both hands to fiddle with wire nuts.Another advantage of the adapters is that ten years from now when it is time to replace the alarms again, if I want to go back to Kidde all I have to do is remove the adapters and reuse the original wiring. These things made an all-weekend task into just a couple of hours of going up and down the ladder. HIGHLY RECOMMENDED!Downsides: I do wish they sold them in something more practical like 4-packs or 6-packs, but the 12-back was very close to what I needed. And the adapter can be a bit clumsy to push into a crowded wiring box. But don't let those sway you, these things are great.

Simple and perfect for the job at hand... which was retro-fitting First Alert smoke alarms into a kidde wiring harness.

This item makes swapping a Kidde for First Alart/BRK smoke alarm very quick and easy.For what it is (a wire, with 2 plastic connectors), however, it is severely overpriced. The per-unit cost here would be acceptable, if it was possible to buy these in smaller quantities (ie: a 3 or 6-pack).In my case, I expected to need 3, and figured this would be worth the time savings. Unfortunately I unexpectedly found one of those 3 alarms was neither wired nor interconnected ... leaving me with 10 of these that I hope to be able to resell . . .

*****BEWARE****** This pigtail is for Firex model # i4618A & others !! I purchased First Alert model SC9120B & needed the conversion pigtail. Amazon sells (2) different pigtails. Be sure you purchase the correct one that you need. Mine needed the triangular shaped male connector to the female connector on old Firex pigtail. Sure you can actually replace the original pigtail that comes with the new detector, however, these conversion adapters (pigtail) make the job so much easier. Btw I went from a regular hardwired smoke detector (with battery b/u) to the new First Alert Smoke/Carbon Monoxide detector. A little more pricey, but, more peace of mind !!!

Whoever came up with the idea to create these adapters was brilliant. I have 9 fire alarms in my house, with 2 being so old they had to be rewired manually. It was a tiring process that took about an hour to get the wires fitted and working properly. The other 7 had the listed adapters and only took 20 mins to install COMBINED. I love when spending a little extra saves me time out of my day.

Triple read the fitment/compatibility before ordering. They didn't fit my listed model. Returned.

Easy to use. Adapters work great. Would be even better if you can purchase in smaller quantities.

Super compatible facile à installwr

These things saved me from having to rewire the new smoke detectors. I chose First Alert and they plug right in.

The product is so easy to install. It is well worth the money, but like everyone else's review, it would be nice to buy a smaller package of these. I needed 3 and I had to buy 12. Either way it is good value but a little bit wasteful in my opinion.

While they appear to work, in converting Kidde hard-wiring to be compatible to First Alert detectors, do these adapters come any fewer than in units of 12?? As with the general population, I have only so many smoke detectors in my home. For the average apartment or house, 6-8 may be more reasonable a number. While a 12-pack minimum does generate a minimum revenue for the seller, it also means wasted materials (wiring and eco-unfriendly plastic) that eventually end up in landfill as excess unused supply. NOT socially responsible on the part of BRK, and a sheer waste of manufacturing resources all round.
