FireGard Closing System | Commerical Garage Door Accessory
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. The product is ideal for applications where there is minimal wall clearance, or where design requirements dictate the need to hide the coil box into ceiling construction.
AlarmGard® Closing System Benefits:
- Automatic reset plus automatic open eliminates reset downtime by 100% after alarm clears
- Activates the door to close upon alarm, eliminating fire and smoke migration – performance that thermally activated systems simply cannot match
- Eliminates visually distracting release devices and fusible links
- Smaller headroom clearance than competitors’ product
- Activated drop speed does not exceed 9 to 12 inches per second
- Cornell AlarmGard® motor, chain and crank operators are UL listed and approved for retrofit to most manufacturers’ fire doors while maintaining the original fire protection rating
