  • Link+ Network: Connect up to 18 compatible X-Sense Link+ alarms, including SC07-W, SC01-W, and SC06-W. An optional X-Sense remote control, sold separately, lets you test or silence connected alarms together.
  • 10-Year Battery: The sealed lithium battery provides up to 10 years of power, helping reduce battery replacements and routine maintenance. No hardwiring is required.
  • Safety Standards: ETL listed and tested for compliance with UL 217, the smoke alarm includes automatic self-checks to monitor sensor and battery status. Its fire-resistant housing provides added protection.
  • Fewer False Alarms: The photoelectric sensor helps reduce nuisance alarms caused by cooking fumes and steam. Use the test/silence button for routine testing or silencing, and install the alarm in minutes with the included hardware.

They connect to each other

[This review was collected as part of a promotion.] As a mom I want to have my house as secure and safe as possible and these smoke alarms help me do just that. They connect to each other so if one alerts all of them sound! I was able to install them myself and the connection was very easy too. They are light weight and average size. You dont need to change batteries as they come with it

Easy to install smoke alarms that look cute as well

[This review was collected as part of a promotion.] Super easy instalment of the smoke alarm. There were six in a box so we added it in different rooms. Once you click the button, it is automatically on so no need to add anything else.
