What does interlinked smoke alarms mean

Interconnected alarms are linked together via wiring or wireless communications, enabling them to communicate with each other.

When one alarm detects smoke or carbon monoxide, it sends a signal to all other connected alarms, triggering them to sound.

This coordinated system provides wider coverage and increases the likelihood that everyone in the home will be alerted to a fire, no matter where it starts.

Alarms can be connected to each other either hardwired (with a wire between each unit) or wirelessly (using signals like radio frequency or Bluetooth).
