X-SenseSmart Smoke Detector Carbon Monoxide Detector Combo, Battery-Operated (Not AC Hardwired) Interconnected Combination Smoke Carbon Monoxide Detector, 5 Detectors with 1 Base Station, SC07-MR51

One of my smoke alarms recently failed, which caused it to go off in the middle of the night. The problem is that my system is all wired together so when one alarm triggers, they all do. This is great in terms of safety, but it's not easy to determine which of the devices has failed when they are all run together. In most cases these smoke alarms all get installed at the same time, so generally speaking when one goes, it means the others aren't too far behind. To avoid the annoyance of troubleshooting, and assuming that the rest of the system may start to fail, I bought the X-sense package.Setup was extremely easy. Once I plugged in the base station and connected it to my Wi-Fi network it literally took a few minutes to get the other alarms configured and assigned to different rooms. I did have to replace the ceiling plates to accommodate but I was able to use the included anchors and hardware to get the job done. I was also able to use one screw from the previous installation to get the ceiling plate lined up. It made the installation of the ceiling plate easier. Once that was done, it was just a matter of naming the different devices, activating them and putting them up.I love the fact that you can monitor each alarm separately from the app. You get an individual tab for each device in the app that shows device status, and you can test them individually from there. The system is also expandable. Overall, I'm very happy with the price, features and functionality. Highly recommended.

As advertised. Very easy to set up and install. The only hiccup was the mounting plates had a different hole pattern than the ones I was replacing and that required a little extra work. Base station joined my WiFi network easily and the system made adding and naming each alarm super easy. I really like this system. Ten yr battery life can easily be tracked in the app (just In case). Haven't checked overall function yet, but plan to induce a controlled event to validate effectiveness in the near future.

This is a great kit and I installed a total of 8 of these for all around coverage of my home. They are easy to pair and install and I really like how the hub can talk to you when your pairing these to let you know everything is setup.The hub can be installed anywhere in your home and it's super simple to get connected to your network with the mobile application.The mobile application is also leaps and bound better than the cheap Smart Life wifi detectors I had previously got several reasons.First you can test each alarm remotely with the app so no need to stretch to reach the test button or grab a step stool.Second when one is triggered the notification to your phone is instant and it tells you the exact one that was triggered so no guessing. The hub also communicates that information as well.Third the app shows you in real time what the detectors are detecting smoke and CO wise so if you ever smell something you can just open the app and put your mind at ease that something isn't burning.The one fires all fires works great as well during my testing when one fires the others all fired within two seconds which is perfect. I also like how I can silence the alarms via the app instead of trying to reach for a hush button on the alarm itself.As you can tell the app really sets these apart from the competition.Now and most importantly here is how they perform, to test the sensors I took a burning candle, blew it out then let the smoke hit the detector and it fired within seconds of that which is awesome. Next step wa shaving my wife use a pan and burn some butter, this would normally set of nuesent alarms with my old ones but these could tell the difference and did not fire.Final test was CO which to me is the most important part since you can't smell or detect it. To test these I took a propane torch and held a metal bucket over the flame to capture the exhaust wearing a pair of gloves. I then put my dedicated first alert CO detector in the buck while it was upside down to make sure their was CO which there was. I then got the buck right under the detector and then flipped it over so the fumes in the bucket would rise to the detector and within a few seconds it fired as CO alarm with the levels it was showing being nearly the same as my first alert one. I also really like how the app told me it was CO vs. smoke.So bottom line this works fantastic, the app is awesome and they are affordable.

Easy to set up the base and detectors. All detectors went off individually when tested and together during the "alarm drill" function on the app. The app is intuitive and helpful, but you'll get constant nag screens asking you to sign up for their paid monitoring service. I already said no to it once and that should be enough for them. The units I got are already a year old and I saw other reviews indicating that also, so beware you'll probably get ones that already have 10% of the life you paid for used up. Apparently, Amazon doesn't use the FIFO method of product rotation.

Exceptionally made well. The sirens are loud and they are digital. These are WiFi and battery backed up. Very impressive and well worth the money. Also have co2 sensors built in. Def will be purchasing more!!

We have been looking for easy to install smoke and carbon monoxide detectors and we finally found them!The set up was so seamless—we connected the base station and then one by one connected each Smoke/Carbon Monoxide detector. If one goes off, they all go off. They are plenty loud, and if any of them should go off, it alerts you on your smart phone and the base station right away. This has surely helped us to have peace of mind when we are away or asleep at night.It says it has a 10 year battery life but having just installed these, I can’t speak to that and will see how well they hold up.You can also use other X Sense products and connect them through the same app and base station making your home feel so much more secure.The price was also comparable to standard detectors that aren’t connected to anything to alert you if you are away. We felt like this was a really great deal and well worth the money spent!Overall, we are really satisfied with these and highly recommend to anyone looking to upgrade or install detectors in their home or business.
