The annual fire test reaches the shutter last in the round. A technician presses the release, and everyone in the aisle watches a curtain that has not moved in a year drop across the opening. On a good day it lands on the sill and the visit moves on. On the bad day, it stops short, leaving a metre of clear air between the bottom rail and the floor.
We build industrial doors at our own factory, and fire shutters are the one line whose failures stay silent. Nothing judders, nothing leaks, nothing slows the shift while a fire shutter decays. The first symptom is the one nobody wants, so a fire shutter inspection routine exists to surface it early. It runs on three clocks: weekly, monthly and annual.
