What is the meaning of "interconnected" smoke detectors?

Interconnected smoke detectors refer to a system where multiple detectors are wired together in such a way that if one detector senses smoke or fire, all detectors in the system will sound their alarms simultaneously. This feature enhances the safety of the premises by ensuring that occupants are alerted no matter where a fire starts within the area covered by the smoke detectors. The synchronized alarm response helps to provide an early warning to evacuate, reducing the risk of injury or harm.

This definition underscores the importance of interconnected systems in providing comprehensive coverage and alerts, contrasting with smoke detectors that operate independently or are solely battery-operated without the added benefits of synchronized alerting.
