Can smoke detectors be interconnected in a building?

Interconnecting smoke detectors within a building enhances fire safety by ensuring that when one detector senses smoke or fire, all interconnected units will sound an alarm. This feature is particularly important in larger buildings or multi-story residences, as it provides immediate notification to all occupants, even those who may not be in proximity to the source of smoke or fire.

When smoke detectors are interconnected, they work collaboratively to create a comprehensive alert system that can effectively warn all occupants, helping to ensure quicker evacuation and potentially saving lives. This capability is a standard feature of many modern smoke detection systems and is encouraged in fire safety regulations.

The other options do not align with the current safety guidelines or technological capabilities of smoke detection systems. Standalone units do not provide the collective alert needed in larger spaces, and limitations based on brand or type of occupancy incorrectly restricts the application of this life-saving feature.
