What does the term "interconnected" mean in the context of smoke detectors?

In the context of smoke detectors, the term "interconnected" refers to the ability of multiple smoke detectors to communicate with each other for alarm response. This means that when one detector senses smoke or a fire, it triggers the alarms on all the interconnected smoke detectors in the system. This feature provides an enhanced level of safety, as it alerts occupants throughout a larger area or building, even if the smoke is detected far from the location of the initial alarm.

The other options, while they address different aspects of smoke detectors, do not define "interconnected." Operating on different power sources would imply a level of independence rather than the cooperative function of interconnected systems. Installing smoke detectors in various buildings does not pertain to the communicative nature of interconnected alarms, and using the same battery type focuses on individual devices rather than their collaborative alarms. Understanding the concept of interconnected smoke detectors is crucial for ensuring comprehensive fire safety in residential and commercial settings.
