For maintenance of the integrity of compartmentation the fire dampers shall have an E classification to EN 13501-3.

Refer to Approved Document B (ADB).

The interlocking ribbed blades shall be held out of the airstream against constant force springs by a fusible link.

The fusible link shall have a melting temperature of 72°C. The link melting shall allow the springs to close the damper.

The fusible link assembly shall be installed so that test release may be made safely from either side of the damper.

The BSB FD fire damper shall have a tested or assessed installation method that matches the requirement of the supporting construction into which it is built.
