TL;DR
A smoke alarm interconnect is the wiring or wireless link that makes every alarm in a house sound together when any single unit detects smoke. The IRC requires interconnection in new construction and many remodels, traditionally via a third (red) conductor in 14/3 cable, with listed RF-linked alarms now accepted as an equivalent.

It matters most at night, when a basement alarm alone may never wake someone sleeping two floors up.
