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.

Awesome fire alarms

Awesome fire alarms. All 5 of my old ones went off over and over cause they were so old. These fit in the same spots my older wired alarms were. These came already paired and went up on same screws. Feel much safer. Highly recommend.

Excellent product

Excellent product, I switched because I got tired of false alarms during quick power failures that would cause all the alarms to sound in the middle of the night.

My only complaint is that the circumference of the new units are smaller than the typical box store units that I’m replacing. They show old paint marks etc.

I had to leave the old mounting plates in place and mount the new one on top of them to hide the old paint marks.

I purchased the 10 year battery smoke alarms for rental houses

I purchased the 10 year battery smoke alarms for rental houses. Smoke alarms have to have a ten year battery if they are rented to a Section Eight eligibil tenant.
