A critical trend in building codes and safety engineering is the closer integration of normal and emergency lighting with fire alarm systems. Advanced addressable systems can now receive a signal from the fire alarm panel and instantly reconstitute the lighting. For example, upon a fire alarm, all general lighting in exit paths can be set to 100% output, specific luminaires can flash to indicate the safest egress route away from the fire (dynamic exit signage), and lights in areas of refuge can be controlled to guide first responders. This two-way communication creates a more intelligent, responsive, and effective life safety ecosystem, where lighting plays an active, dynamic role in emergency guidance rather than a passive, static one.
