This hardwired unit offers the ultimate peace of mind by linking up to 18 alarms throughout your home, ensuring that a fire in the basement triggers an alert in the bedroom. While the ionization sensor is specifically tuned for fast-flaming fires, the battery backup guarantees you remain protected even when the power grid fails.

This interconnected system ensures that when one alarm triggers, the entire house wakes up, providing a critical layer of safety for larger homes. While ionization sensors are highly sensitive to fast-flaming fires, the precision detection tech effectively cuts down on the nuisance alarms that usually plague kitchen-adjacent units.

This hardwired essential prioritizes rapid detection, using ionization technology to catch invisible fire particles before they spread. While the installation requires a bit more effort than a simple peel-and-stick model, the peace of mind provided by its interconnectable network and reliable battery backup makes it a non-negotiable upgrade for any home.
