Fire Damper Fusible Link Replacement. Replacing fusible link on a combination fire smoke damper: Visually inspect the damper for damage and verify that the fusible link is in place and has not activated. Replaced an old package hvac unit on the roof of an apartment building, for a unit on the first floor. Links installed in smoke / fire dampers, fire doors, and smoke hatches exposed to fluctuations in ambient air temperatures can cause alloys or solders to crack or partially melt and then reform changing the characteristics and temperature set points and response times of fusible links. These links are recommended to be installed in ambient temperature s of 100˚f. 1) if fail closed, disconnect power and/or air pressure from damper. This document’s intent is to provide a basic introduction to fire & smoke damper actuator replacement. Discovered that there was a fire. Most fire dampers installed utilize a 165˚f (74˚c) fusible link. While automated systems or smoke alarms control some dampers, a fusible link fire damper is controlled by the fire itself. The fusible link is sensitive to high temperatures and remains open until exposed to high heat, such as that from a fire.
