UL 2525 Listed Area of Refuge Systems
What are UL 2525 Listed Area of Refuge Systems?
UL 2525 Listed systems are distinct from non-listed Area of Refuge systems. UL 2525 is a performance standard that expands specificity over NFPA 72 (2022) by defining operational, acoustic, environmental, and electrical performance.
From stairway landings to elevator lobbies, these systems ensure that all building occupants have a way to call for help and be rescued quickly, even in the most critical moments. Individuals with mobility challenges or those needing evacuation assistance can use these systems to communicate with emergency responders when they reach designated safe areas.
