Fusible Links: Rating, Condition, and Replacement

Fire/Smoke Dampers, Rated Assemblies & AccessSTOP / VERIFYField judgment

Core Answer

Match the fusible link to the exact damper listing and approved submittal, keep it undamaged, and replace it only with the specified listed part.

Can we verify the correct fusible-link rating and listed replacement part for this exact damper before I install it?

Do not substitute a different temperature rating, bend the link to make it fit, paint it, or reuse a damaged link.

The wrong or damaged link can close too early, fail to release, or make the listed damper installation unacceptable.

Verify against: damper listing, manufacturer installation instructions, approved submittal, project life-safety documents.
