How does FireGard compare to other fusible link systems?

With so many different types of activation, options and accessories available for coiling fire doors, let's see how Cornell's FireGard compares to other fusible link systems in the marketplace.

FireGard with Release Device Activation

FireGard with release device activation changes a traditional fire door or shutter to proactive closing system that responds much more quickly in the event of a fire. By tying into the local fire alarm or smoke detectors, the device can instantly eject the fusible link arrangement allowing the fire door to close in a safe and controlled speed.

AlarmGard's automation advantages saves time and money

See how the AlarmGard's automatic closing and reset system works without any human interaction, saving you time and money as compared to other closing systems.

Cornell's AlarmGard Advanced Fire Door Closing System

The AlarmGard® Closing System is activated electrically by the central fire alarm system or by local smoke detectors. When this occurs, the integrated release device allows fire doors to close safely without loss of door spring tension. This advanced system does not require human interaction after the alarm is cleared – it will reset and reopen automatically.
