X-Sense Smart Heat Alarm XH02-M with 10-Year Sealed Battery, SBS50 Base Station Required, Model XH02-M, 1-Pack

Works well with the X-Sense system. Note that this is the model which requires the X-sense hub and it does not support Wifi. I personally think this is a far better solution than the Wifi models. These alarms form their own network and communicate with each other regardless of whether your wifi is functional. Then if an alarm goes off, one alarm will set off all the alarms. I have some back rooms in my basement where we could not possibly hear an alarm if we were sleeping on the second floor, so this one feature is really the very most important feature in my view--it's the whole reason I went with these type of X-sense alarms.Their Hub is nearly free if you buy a 3 pack of the smoke and CO alarms. I have manyu if those as well, and I added 3 of these heat alarms for kitchen, garage, and furnace room (where heat rather than smoke alarms are recommended). At this point I have 14 X-Sense alarms and I am really happy and feel certain we would know right away if there was a fire or carbon monoxide problem. They do also have a similar model which does not use a hub. The only pupose of the hub it to provide access via an app, the hub is not required for alarm function. So you can get the hub kind or the non-hub kind, and note they are different models. If you don't want to mess with an app or hub, get the other kind. I like how the hub lets me set off tests and see battery and RF signal levels. The hub is more about monitoring device health and is not required to be online for alarm function to work.Again, just personal advice, but don't get the wifi ones. Get the ones that form their own network independently from Wifi. The independent network models require nothing except the battery powered alarms themselves for one to set off all. Meaning even if you have no power, no internet, no wifi, they will work exactly as intended. I work as a computer network engineer and know what I am talking about--Wifi is bad for this application.

The X-sense system is amazing! We have a large house with a solid door between the hallway and garage and if upstairs, it is impossible to hear a smoke detector in the garage. The X-sense system solves that issue by announcing that the garage sensor is activated on all other detectors (I have the voice alert system. NOT ALL X-sense systems work this way) This sensor works on rapid heat rise and not smoke so it is also great for the kitchen so you don't have a lot of false alarms if you like to fry stuff, for example. All told, I have bought 2 X-sense systems and shared one with my mom as well. I think every house should have a system like this. Lives would be saved for sure!

Very easy to set up. Bought the base with it so I could had additional units as needed. Alarm is loud and useful.

After looking for new detectors for years, these fit the bill. I finally figured out you will never find a duel smoke and fire alarm, with a CO detector. These detect smoke and CO. The app is great. Easy setup. I bought some fire detecing units from the same Company and put those in the Laundry and kitchen. Great set up.

Good quality comes with all needed items to mount to ceiling.

It all started with a mailbox sensor. I researched all that was offered on Amazon and decided on X-Sense. I am so glad I did. I now also have a driveway sensor, multiple door and window alarms, motion sensors, 6 keypads, smoke and heat alarms, water sensors, temperature and humidity sensors. I have a complete security system and a complete safety system. X-Sense tells you you can have 50 devices on a base station. What it doesn't tell you is that you can have multiple base stations. I have 2, one named security and one named safety. I control everything from the app and get notifications for everything. The available settings in the app are extensive, including naming the device, naming its location, choosing a notification sound, etc. You can set the security alarm for off, home and away. You can set the motion sensors to only function when in away mode. I am just extremely satisfied with everything. Choose a device, tap a button on the app, double tap a button on the device, it connects and you are done. If desired you can then tweek things, even editing the order the devices show up on the screen in the app, as well as naming and renaming whatever you want.

good product

Easy installation, app works great!
