Upgrade to new style smoke detector
Item came with plug adaptor to match old model wiring harness. With the instructions it was easy to change to updated plug and mounting ring. Changed out the old and installed the new in less than 15 minutes. Now I’m good for several more years of protection,

Smooth Replacement
Had 6 smoke detectors that were at their 10 year life span and needed replacing. Ordered these, arrived in a couple of days and replacement went smoothly, (no need to replace the ceiling mounting, thank you very much!), set for another 10 years!

Adapters included
I never leave reviews, but I was so impressed I had to send one ouy. I looked up my model number and ordered a replacement. When I went to install it, but the wire insert didn’t work, so I figured I would have to rewire it. Low and behold, the smoke detector came with the adapters! Way to know ahead of time what I would need! Thanks! 🙂

Replacements for old Kidde interconnected alarms
Like several others before me, my old Kidde IB interconnected alarms started giving me the end-of-life 2 chirps every thirty seconds this weekend, one by one. I find that to be ridiculous – that a product just decides it’s time to stop working because of time. You can’t cancel it, you can’t pause it. I doubt it has anything to do with actual performance, but rather a set “time” that it just stops functioning. What if your phone decided after 2 years it would stop working? Or your TV? Not because it wasn’t performing, but because they put an “end of life timer” in it? Really sad. And frankly, it sounds like these have the same “feature.” Although I read that these have 10 year lifespans, which is much better than the 6 of the IB models, it’s still annoying.In any event, I bought 3, one for each level of my home. Replacement was mostly a breeze, two snapped in with the same wire connectors as the IB models before them, so there was no rewiring to be done. Twist off the old, unplug, take the new one, pull out the “pull tab” to initiate it, then plug it in and twist it. The only trick here was that one of the new ones, the connectors were slightly off center from the “holes” for the plug, so it took a lot of elbow grease to get it to finally connect and stay connected. Tested each, which because they are connected, each one causes the others to go off as well. Success!Tested while frying up some bacon, and they kicked off like they were supposed to. So I know they’re working, at least for smoke!There are a couple of concerns I have with these – they run off 2 AA batteries. The old ones ran off a 9-volt. I have concerns about the longevity of 2AA vs 1 9-volt. But time will tell. Also, I find it odd that they’ll put voice to “carbon monoxide” and “fire”, but all of the other warnings such as battery life or end of life warnings are chirps that you need to look at the key to decipher. So weird.The best part of these is that I really like the placement of the batteries in the new one – on the surface! So you don’t have to remove the unit to replace the batteries now, just pull open the battery compartment and replace in place! That’s a nice touch, for sure.At the lower end price point of interconnected smoke alarms, I’m decently happy with these for now. Of course, I’ve only had them for a few days. I just hope they last much longer than the IB model.

Excellent, it was plug and play. It sounds few seconds, then the next sensor on the lower level sounds few seconds, then the next sensor on the basement sound few seconds as well, then it is ready and silent.I got scared when it started sounding because the other 2 sensors are not the same brand; they were already installed, so I thought they were not compatible, but fortunately they just need around 1 min to talk each other and set up. They shut off by themselves after around a minute. A bit scaring but it is part of the process.Thanks

I liked the fact that it was so easy to install! Our existing device expired and recently there have been a number of carbon monoxide poisoning in our city! I feel much safer having replaced the old device!

I had an existing smoke detector in my home which I purchased 20 years ago. I believe that I recently heard that you must change them every 10 years to ensure that they are going to work when needed. Well, no point in having them if they are going to work so I ordered these. I have been slowly upgrading most things in my home to smart devices and since smoke and CO detectors are so important, thought it best to do so with these also. I have never had on in my basement which is, IMO, where one is most needed. It did require me doing some electrical work because it does need a box to mount on, but that was no issue. If you are not able to do this yourself, hire an electrician, it is less than an hours work. If you are simply replacing existing detectors, it takes seconds. To be honest, I cant say how good the instructions are as I didn’t read them. These devices have 3 wires (white, black and ground) an it is simple to connect. Once they are both installed, they piggy back on your Wi-Fi to communicate with each other. If one is tripped, they both go off. The only feature that they are missing is a safety light once activated but, truthfully, a bright light in a smoky hall is actually blinding anyway, These are a great value at 120 for the pair. Many others smart devices cost that for an individual unit.

My personal opinion is that these are needlessly complicated compared to older detectors; but I can understand arguments for having an integrated system of detectors. They could be improved by avoiding proprietary features allowing safe integration of any detector. Safety first!This was a one-for-one straight replacement of an older version of the exact same detector. I had the original manual which indicated that the warning beep that the older detector emitted indicated a pre-expiry-date failure of the alarm. I’m not an expert, so I had to wing-and-prayer trust my interpretation of the manual.The packaged arrived from Amazon in one of their plastic bags, and had been crushed in shipping (see image of unopened box) resulting in the distortion of the three connector pins. Despite this, I was able to reshape the pins with pliers and install the detector in the original carriage.No beep. Tested and working. Problem solved.I would say that if it can survive this abuse and still do the job, then it’s a pretty good product.

This unit was a direct replacement of an existing one. Electrical connections were correct and the detector easily attached to the existing base on the ceiling.
