Where is the exact placement for an access door next to a fire damper?

2nd YearDampersRED · Stop / Verify

The access door must be installed directly in line with the fusible link side of the damper blade assembly. It must be large enough to allow an inspector to easily reach their entire arm inside to manual-test the damper drop, swap out a melted thermal link, or reset the blade stack.

Field checklist

Ask Foreman

Hey boss, I’m on dampers and need verification before I touch this: Where is the exact placement for an access door next to a fire damper? Do you want me to stop here and check the approved detail, submittal, or inspector/manufacturer requirement first?
