Individually tested for reliability, these alarms can be seamlessly interlinked, so when one sounds, all emit a powerful 85-decibel alert. The bundle also supports integration with the optional Home Hub (sold separately), letting you monitor and manage your system directly from your phone for total control.

The included heat alarm is ideal for high-risk areas like kitchens or garages, activating only at temperatures between 54°C and 65°C, unaffected by everyday cooking fumes. It comes equipped with a sealed 10-year lithium battery for maintenance-free protection.

Meanwhile, the X-Sense optical smoke alarms are fitted with photoelectric sensors that detect smoke efficiently while reducing false alarms. Each unit is protected with a built-in insect mesh and powered by a replaceable 3V CR123A lithium battery, ensuring long-term, reliable performance.
