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.

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

This detector was placed in the place of the old detectors, and one of them started making noises for no reason. It had been going off in the middle of the night for no apparent reason. I immediately removed it because my neighbors were complaining. But the seller received my question, gave me a solution, and I have not had the same problem since. Very professional. Recommend.

Purchased to replace an old smoke detector that was no longer in good shape.
Installation wise it was very easy and I had a chance to test it out and the device triggered correctly and the sound level was great to wake up the whole house if there was a problem at night.
I highly recommend this product.
