X-Sense10-Year Battery Combination Smoke Carbon Monoxide Alarm Detector with Large LCD Display (Standalone Model)

I ordered the three pack for use in important areas of the house. Test function operated flawlessly and having a battery that lasts ten years is awesome! Installation is simple and pairing went as described, plus having the remote for testing and silencing is bonus. I do wish that the led screen could be checked and read without the unit having to alarm to have it backlit. I am glad that I chose the X-sense system to protect my family.

The X-Sense Smoke+Carbon monoxide detectors with 10 year batteries were simple to install. I was able to use the anchors already in my ceiling for the smoke detectors I replaced just having to add one additional anchor. They look good and all worked great when I tested them. Overall, I’m very pleased with this purchase so far.

These are a great option when hard wiring is not feasible in some homes. They have a 10 year lifespan and 10 year sealed battery. Very economical and easy to set up.

Well we just got these to replace some that were very old and not interconnected. We got 9 (6 pack and 3 pack) to go in every room of the house except bathrooms (due to humidity). We have 9’ ceilings and the old ones hung on the wall right above the door frames ... after reading about best placement I chose to install these on the ceiling even though I’ll have to use a ladder to test. If you can’t place in the center of the room due to a fan make sure it’s at least 3’ away but not in the corners. Also it says at least 10’ from an oven or stove to prevent false alarms. This makes sense as our last kitchen was smaller and the alarm was about 5’ away from the oven and would go off every time I cooked and opened the oven. We used to joke that dinner was ready when the alarm went off. Anyway- these were easy to install but as another reviewer stated the bracket doesn’t line up with the top and you have to place the whole thing on the ceiling, hold the bracket and carefully remove the alarm without moving and install to get it facing the way you want. (I learned this after the first one was lightly off center) I used a push pin 📌 to help hold it in place until I got the first screw in. I did this alone but it might be helpful to have a second person to hand you the drill or screws or whatever. Thankfully my ladder had a tray on top. In the instructions I missed that you have to pair them manually and just assumed they would all talk to each other. Thankfully I questioned this and looked at the manual again. Pairing is super simple and only takes a few seconds. You can set up different zones too if you don’t want them all on the same group. I put mine all together. Take the first one and press button 4 times quickly then press second alarm twice quickly and they will blink some then beep and they are paired. Just repeat this process with an alarm from the group you want to add to. I already had mine installed so I had to take one around the house and pair them all to it but this would be a very simple process to pair them all before installing. To test the group hold the button in while you test. It will beep several times on the initiating alarm then the rest in the group will start beeping too. Warning this will be extremely loud! Ear plugs/muffs are recommended during this process. My dog was not happy with me after I went around the house making sure they are all alarming after pairing everything. I think I’ll put her outside first next time. Assuming these detect smoke and carbon monoxide accurately (I’ve not tested this other than hitting the test button) I’m confident that the entire house will alarm and wake us from a deep sleep if necessary! Did I mention that these are extremely loud? Also I’m glad these should last around 10 years or so because I figure in that time the technology may be more advanced and they’ll need to be replaced anyway. That way we won’t be stuck with some dinosaurs that are out dated like we were before these. So far I’m happy with my purchase and feel safer in my home.

went up easily. i can not advise on how it works as we have not had a fire or Co2 event.but amazon just flashed peace of mind, size, connectivity, speed and reliability so i typed it

I purchased a 3-pack to use in strategic locations around the home. These next generation detectors offer three desirable features that raise them to near the top of their class.(1) Combined smoke and carbon dioxide alerts. Rather than purchase two detectors, let one do the jobs of two and save money.(2) Ten-year internal batteries. No more 9-volt battery replacements every year. More savings and less hassle. And at the end of the ten year power cycle, the detectors will chirp to let you know that replacement time has come. Turning off the alert requires a little twist and this will deactivate the detector.(3) Optional Interconnection. Most stand alone detectors will alert you within a limited area of use, but what happens if you are not nearby to hear the alarm? The optional wireless interconnection solves this problem by sending a signal to the other detectors in the group, and these will sound off.Wireless interconnection is optional; just don't turn it on. Note: The detector is delivered tuned OFF. Once the detector is turned inside of the mounting ring it will be activated.Important mounting notes. Each detector comes with a mounting ring that holds the detector. If you want the detector display to be horizontal to the floor, then attach the detector to the ring (which activates it), designate a mounting location, and mark the location on the wall/ceiling/other and the orientation of the ring. Remove the ring from the detector, reposition the ring at the marked mounting location, pencil mark the drill holes before drilling, drill the holes, and drive in the screws. The detector will now turn into the mounting ring with the display oriented as desired.

I left a similar review on the Wi-Fi connected version so I will keep this short and sweet. I wanted to have some 'dumb' detectors for my bedrooms and smart ones for each floor. I like that at a glance they look the same so you don't have a weird looking mish-mash.Easy to setup, all hardware was included. Nicely packaged. The feel solid and look good. Very satisfied so far, the only thing I can't speak to is if they will last 10 years or not.

Seems very quality and incredibly easy to do total swap out of all. Installation and activation/testing very straight forward. Now “when one randomly fails because you forgot to change all”, may be a thing of the past.
