What is a Release Device?
The FireGard Fusible Link Closing System can be ordered with a fail-safe release device that responds to alarm signals and permits the fire door to close prior to smoke migration or the high temperatures required to melt the fusible link. This option is suitable for applications that can offer more wall space for the installation of the device and where aesthetics are less important.
