A rolling fire door can look like just another opening in a warehouse, distribution center, parking facility, or commercial building, until a fire occurs. Then it has one job: to close as designed to slow the movement of fire and smoke, protect exit routes, and help limit property damage. That job depends on much more than the door itself. It depends on the curtain or panels, tracks, counterbalance system, release device, operator, alarm connection, and clear opening all working together.
