Kidde Quick Connect Smoke Detector Adapter Plug, Smoke Alarm Wiring Harness, Compatible with Kidde Hardwired Smoke, Carbon Monoxide, & Combination Smoke & Carbon Monoxide Detectors

When I was repainting the interior of my home, I decided it was a good tome to replace my fire / carbon monoxide / smoke detectors as well. I had the older style Kiddie alarm connector and DID NOT want to have to do any complicated wiring. This harness served as an easy adapter and fit perfectly. Great design, easy to use. Would recommend.

The Kidde Quick Connect Smoke Detector Adapter Plug is a must-have for anyone upgrading or replacing their smoke detectors. It makes the installation process incredibly easy by allowing you to quickly connect your hardwired smoke or carbon monoxide detector without the hassle of complicated wiring. The adapter plug is compatible with Kidde smoke alarms, carbon monoxide detectors, and combination units, providing versatility for different safety needs. The design is simple yet effective, and it ensures a secure connection for reliable performance. I love how much time and effort it saves during installation, especially when compared to traditional wiring methods. It’s durable and well-made, so I feel confident in its long-lasting use. Overall, this adapter plug is a game changer for quick and safe smoke detector installations.

Worked perfectly. Time saver and I was able to replace all of my alarms with the updated version with confidence. I was a little worried about redoing the wires myself since the shape of the plug had changed on the new alarms. Worth the few extra dollars. I did need to carefully stuff the wires in a few of the boxes, not much extra room up there, but easily worked around.

Excellent product to replace expired smoke detector. Easy to install and covers the spot where the old one was installed.

So happy to find this adapter on Amazon. Not found in the stores. Why Kidde changed their connector is beyond me. Allows a quick swap with no rewiring. Worked great! Saved a lot of time.

It’s the only way to avoid messing with wires.

For whatever reason$, Kidde changed up the wiring harnesses and connectors on their newer hardwired detectors so if you are replacing existing hardwire Kidde detectors that have reached end of life, you either need to re-wire them with the new stuff (provided with the detectors) or make it super-easy on yourself by buying one of these adapters for each detector you are replacing. These cost less than $5 bucks at h*me d*pot but good luck finding them in stock. for a ~55% premium (I paid $7.77 per) I had them from Amazon in less than 2 days. Unless you have absolutely no idea what you're doing (no judgment here!), changing out the wiring harness DIY is a very doable job, but unless you're extremely quick the time savings these provided were well worth $7.77 a pop. And if you don't know what you're doing with electricity (again, no judgement here) you'll essentially eliminate any risk of shock/electrocution using these in lieu of rewiring, again well worth it at under $8 per detector. It took me about a minute to swap out each detector using these adaptors and I didn't have to worry about screwing up...to remove the old harness and rewire the new probably would have taken me about 10 minutes per detector conservatively, not counting cussing at dropped tools and wiring nuts, the annoyance of having to cut power for a while, etc. If you can afford it and/or value your time at more than 50 cents per minute or so, save yourself the headache and buy these. And if you are considering hiring an electrician to wire some new Kidde detectors for you to replace your old ones, this will save you a ton of money and I promise it's easy enough to do yourself.Tested all 7 smoke detectors in my home after installing with these adapters and they worked as expected including interconnection of alarms. Knocked out a job I had been putting off for 2 weeks in less than 20 minutes and enjoyed the rest of the weekend with no chirping (both from the old alarms or from other members of my household annoyed I hadn't replaced them yet).

Quick and easy. Price was worth it and good quality.
