What Is a Fusible Link Fire Damper? A fusible link fire damper is a style of fire damper or smoke damper. 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.

A fusible link fire damper is a style of fire damper that is closed via a fusible link, as opposed to an actuator. There are automated systems or smoke alarms that can control some fire dampers, but the fire itself triggers a fusible link fire damper.

The standard fusible link for Metal-Fab fire dampers is 165° F. Two other fusible links with different temperature set points are available, 212° F and 286° F.

Links, fuse links, and fusible links are integral components within fire protection systems. They serve as crucial triggers, reacting to the presence of heat and initiating a series of actions that mitigate the spread of fire.

What is an EFL device? The Ruskin electronic "resettable" fuse line (EFL) is a UL Classified heat response device for use in conjunction with Ruskin fire/smoke dampers. The EFL is STANDARD on all fire/smoke dampers ordered with electric actuators.

Fuse links play a vital role in fire damper systems by ensuring that the damper blades remain open under normal operating conditions, allowing for the free flow of air. They are designed to activate at specific temperatures, commonly set at 165°F or 212°F (75°C or 100°C).

Model FLD-S-A is a Multi-Blade fire damper with 3V style blades. It is designed for closure of the HVAC duct opening in emergency Fire situations. It is certified to withstand fire conditions for 2 hours as well as 4 hours, as per UL555 testing standards, tested by CBRI Roorkee.

Feb 19, 2024 · Fusible links are essential in helping your suppression system detect fires automatically in your commercial kitchen. To follow the rules set by NFPA 17A, you must change these links every six months. It’s also important to use the right one that matches the heat level of your kitchen appliances.

4 days ago · The fusible link holds the fire damper open until the air around it gets hot. Fusible links are fabricated from metals with low melting points. This makes them more susceptible to heat than the fire damper. A standard fusible link is rated for 165 degrees Fahrenheit. When the air reaches this temperature, the fusible link will melt and break apart.

Mar 29, 2024 · Fusible link fire dampers are also used to prevent the spread of fire. Unlike motorized fire dampers, fusible link fire dampers don’t have actuators and they don’t require a control signal. They are sort of passive fire protection devices.
