Notes:

For openings larger than our maximum sizes, multiple dampers would be required.

 

In a horizontal duct run should the velocity exceed 10m/sec, a spring assisted closure will be required.

 

All fire dampers must be tested when installed and then tested annually to comply with NZ Building Act and Local Council requirements.
