KiddeHardwired Smoke & Carbon Monoxide Detector, AA Battery Backup, Interconnectable, LED Warning Light Indicators, 2 Count (Pack of 1)

I purchased 50 smoke/co detectors to replace standard smoke detectors that I had in hotel rooms to ensure that we will remain up to fire code come August. Out of all 50, I had a single box that didn't include the wires. Every smoke detector worked and all batteries were charged. I went with Kiddie-brand for my purchase because they have always been reliable and we want to ensure we are utilizing quality product when it comes to health and safety.I purchased these because they were an overall cheap option (in comparison with similar models), it has hardwire capability, and because these appeared more modern and sleek. There were other models that would've matched what we had, but these were a great fit overall for our hotel.These can be hardwired, but do not have to be. We did hardwire into our fire protection system, and it was very easy. We simply pulled down the old smoke detectors, loosened the screws for the ceiling mount and pulled the old mount. Then we pulled the wires down, removed the wire caps, and wired in the new wires so that they are tight and snug, and tucked them back into the ceiling. We put the new mount on the existing mounting screws and tightened it down. Then we simply held the battery door, pulled the tab, inserted the wire male end into the female port on the smoke detector and we were done.The only worries I have is that dust may build up on the lip of the smoke detector, and that the battery compartment door is rather flimsy.The packaging is great, and they cover the smoke detectors in a piece of hard plastic and a soft sort of "shower cap" to make sure it's protected even if the box is damaged.Overall, great product. I'll try to remember to update this over the years, but chances are that I'll forget before the day is over!Happy purchasing

these moderately priced smoke detectors installed easily. I have had them for a year and I trust them.

Easy to install. Love that they are a combo of smoke and CO. Be careful to attach wires well. If they are slightly off, it will set all alarms off.

Seems all the replacement Kidde combo detectors have a different electrical clip that requires you to unplug the wire nuts and have to reattach the wire to new clips which some homeowners may not be capable of. Just makes things harder for folks with no benefit. The detector works great once it’s live.

I bought these as replacements for other Kidde detectors that reached their 10-year life span. Installation was very easy.

Bought 6 of these to replace our existing smoke detectors that were shamefully old. Installation took about an hour for all of them, and a large portion of that time was spent figuring out the mislabeled switches on our fusebox. They've been installed for about a week now and we haven't had any weird malfunctions or random beeping yet!

These are nice units, and we had to replace ours that were out of date.

I bought 8 of these and they are awful. I don’t believe they are actually Kiddie products. 6 of the 8!I purchased have failed. I’ve changed batteries and also rewired still fail. Pay a little more and buy “REAL “ Keddie products at a reputable distributor
