FAQs

Will the battery last 10 years? Can it be replaced?: This alarm has a sealed lithium battery that lasts 10 years without needing to be replaced. When the battery is weak, you should replace the entire unit.

How will these alarms notify you when the battery is low?: When the battery becomes low, the red LED light will flash once with one beep every 60 seconds. Each alarm will give its own warning independent from the others.

Can it be connected to Amazon Alexa?: Though this unit is a wireless interconnected combination alarm, it is not Wi-Fi compatible, so it cannot be controlled by an app nor work with any AI assistants. However, you should check out the X-Sense XS01-WX smart Wi-Fi smoke alarm if you want a Wi-Fi alarm.

Does X-Sense provide a combination CO/smoke alarm that can be interconnected with other alarms?: Yes! Our X-Sense Link⁺ series includes smoke alarms, carbon monoxide alarms, and combination smoke and carbon monoxide alarms that can be interlinked with each other to create a wireless security network using advanced RF technology.

Can I customize the wireless network?: Of course yes. Wireless alarms in a multi-pack have been pre-connected and are ready to use. For a customized network, you can simply disconnect the devices from the network, add new devices to the network, or create multiple networks.

Is it safe to install the alarm with heavy-duty fasteners or magnetic pads?: It is not recommended to use heavy-duty fasteners or magnetic pads which could interfere with the device working properly. Instead, mount the alarm to a wall or ceiling with the included mounting bracket, screws, and anchor plugs for safe use.

SD19-W Wireless Interconnected Smoke Alarm

I love these SD19-W Wireless Interconnected Smoke Alarm because they were very easy to program to interconnect!!! The instructions were easy to understand and the customer service was great.

So far so good

The standout feature of this smoke alarm is undoubtedly its 10-year battery life. It gives me a sense of comfort and security knowing that I don't need to worry about replacing the battery for such a long time. It ensures that my home is continuously monitored for smoke and fire hazards without the need for frequent battery changes.

The first test of their smoke detectors was a satisfactory 5, however, drilling into the wall to install them is still not good. Now I want to install them for other apartments as the old detectors are five years old and the only improvement I can see is that the alarm is loud and reassuring, but be sure to cover your ears when testing.

These three fit in my kitchen, living room, and garage very well

Tim C.

Connected 6 alarms together in just a couple of minutes and installed throughout the house. Easy to connect and test. Will buy again if batteries last as long as claimed.

David C.

Works really good. Easy to set up. Been using this product for a lot of my customers now.

These smoke detectors look good on a wall or ceiling, but they are typically large (5 inches in diameter). The LED lights that flash every minute or so are very dim and not intrusive at all. The siren and decibels are consistent with others.

Ryan

Very easy to install. 10 years battery life. Excellent value for money.

Kristeen

Love the idea that they are all connected. Installed all 6, tested each and they seem to work. Decided to actually smoke test it with a piece of burning wood. (safely done) I put the smoking wood directly under 1 siren and the whole room was filled with smoke and the siren never went off.

Helen

I love reviews and prices. I bought 3 in total. Ranch with basement and attached garage. I put one in the basement closest to the gas stove and water heater area. An intermediate house upstairs to avoid hot showers and kitchen stove start up, finally one in the garage

Tabby

The only thing that worries me. According to the instructions, once you connect to the base, it starts with a 10-year battery. The one I bought was already attached to the base and I removed the screw holes that went into the wall. (????) So I don't know if it's a return. So I'm dating them all the same, but I have to worry now if I have one New Don't know when the battery was installed in the living room. ?? Otherwise¡

Jones

This is probably too loud for my tiny house, especially if it goes out easily and there is no smoke. But it definitely wakes up people nearby. Time will tell if it will last 10 years.

Kenneth

Easy to install and a little smaller than previous smoke detectors, but that's about it. Good test. Hope they last the whole 10 years. Seems like a good buy.

Laurie

Nice looking and very loud

Bethesda

The system is self-contained so there won't be 8 alarms screaming when you try to find the initial alarm. Amen. The battery can last 10 years! For easy testing, we installed Velcro strips.

Sherry

Please read the instructions several times. It takes several times to ensure that each detector is connected to each other. The base requires you to use only their screws, otherwise the detector will not connect. They should redesign the base so any screws can be used. I have 8 probes installed and hope they will work properly for the 10 years shown.

Robyn

I'm tired of replacing expensive 9 volt batteries and chasing chirps around the house trying to figure out which one is chirping right now... ?.

Walker

I was worried about installing these, so I looked for a video but couldn't find one for this model. Other videos make it look easy for me to hang them up. I got a pack of 6 because they are connected together. Once I had them all installed I tested and everything was fine. You need to make sure the screw heads are flush, otherwise the device won't lock into place. Hopefully I'll never actually test them, but seems like a good option.

Margaret

Installation instructions say "use an appropriately sized drill" to drill holes for mounting the detector. So what's an "appropriate size"? They could have said "3/16 inch" in the instructions but I had to figure that out myself. Not a big deal, but a complication that could have been avoided. Detector has a manufacture date of 2021-06-26, it arrived 2022-02-22, so it looks as though I should replace it 9 years 4 months after installation. Does it work? Won't know until I have a fire.

Willard

These are excellent plug-and-play upgrades compared to anything over 10 years old. Both of my current ones need power to the house, but these don't. The harder part of the installation might actually be removing the existing old equipment. If there's any downside to these, it's that they have a slightly bulky design, but that's just based on my preference for a streamlined design. Their standout features include easy connection/pairing with other devices, 10 years of battery life and a very loud/audible alarm.

Tammy

Highly recommended! ! We replaced wired smoke detectors with these wirelessly interconnected detectors. Boxes are paired together. We also purchased smoke/CO2 detectors that must be paired. Pairing is very easy. We installed a total of 7 detectors in about 30 minutes.

Interlichia

To be fair they are designed to mount directly to the ceiling and they do provide drywall anchors to do that but I didn't want to put a blank board on the junction box where the old smoke came off so I got it working . No need to connect to 120 volts like the old detectors, working entirely on batteries advertised as 10 years, we'll see if that's true. Overall, very satisfied with this smoke detector system and would recommend it to friends or family.

Philips W.

Super easy to install and perfect test. I don't know how long the battery will last, because it is new, but it can be used now. I would recommend this.

Julieanne

Very satisfied with my purchase. Install the alert immediately after receiving the alert. Easy to install and does not take time. It was a rainy day, so they put the package in a plastic bag. This is great! ! ! Cannot comment on battery life because I only have a short time.

Jayen

Can't say yet. Hope I will never let them disappear. However, if they do, I hope they will work as expected.

Ken

If you register on their website, they will provide an extended warranty. But the registration page does not work. I brought this matter to their attention a few days ago, but there was no response. How can I find servicer?

Gedeon

It may be too noisy for my small house, especially if it can easily go out without smoke. But this will definitely wake up people nearby. Time will tell whether it can last for 10 years.

Brady

It is installed with two screws and anchors. A little smaller than my previous one, so there must be a new installation. When cooking causes an alarm, there is a 10 minute turn-off time. The previous alert lasted for ten years of advertising, and these are similar.

Evans

The smoke alarm is easy to install (I used a magnetic fixing plate) and the instructions are clear and well written. light, The compact equipment fits the ceiling of our bedroom very well. The alarm worked well in the test and the battery life seemed to be very good (but I just installed it).

Barbara

If you are changing the brand, the two holes for ceiling installation may be in different locations, which usually means one or two more holes in the ceiling. I have started to put the old and new bases together, mark the location of the old holes, and drill out the new suitable bases. In this way, the new kit is secured to the original ceiling hole. Cool, right?

Jenna

It is just a smoke detector, but I like that it can be connected with other wireless smoke detectors. We have these three. One is about four years old, in a restaurant near our kitchen. We know it works because if we mess up and burn some food, it will ring like a clockwork. It is very loud.

Pabio

I had to buy this because I put my friend’s smoke alarm in his toaster oven to make it stop beeping when I was drunk and burning frozen pizza, and his roommate did it the next morning It melts when you put a hot pocket. Therefore, smoke detection: 5/5, durability in the oven: 1/5.

DavidOC

It is easy to program multiple units so that they sound the same. A good solution for newer fire codes that require smoke detectors to sound together.

Handy

When following the instructions, it can be easily paired with other X-Sense wireless interconnect detectors. It comes with spare batteries, screws, wall anchors, and several different adapters and wire nuts to hang into existing wires. This is what I need, everything is fine.

Mr. Man

I've had these for several weeks and the wireless system is working well. One of the units was in a separate workshop about 75 feet from my house, and the wireless connection worked fine.

Shelly

The working principle of this smoke detector is the same as advertised. A "wireless network" of the smoke detector is created in your home (please note that this has nothing to do with the WiFi network.) If one of the units detects smoke, all units will alarm. This is a good solution for situations where larger houses and other remote devices may be too far away to be heard. Another nice feature is that you can "turn off" any unit's alarm.

Pete

I have used it in my kitchen, but ionization tends to be provided faster. This doesn't bother me, but if you don't want to know the moment when the popcorn core may be about to catch fire, you may want to move out of the kitchen. There are on every floor of my house. They work together perfectly.

Odaruc

After some tests, they do work very well, and the three are connected to each other...you will have a lot of noise in your house...this is what you want. A great way to update the security of an old house without wiring.

Elizabeth

I won't leave many comments, so I just want to point out that these were delivered the next day, sturdy packaging and made less than 4 months ago, and worked perfectly.
