About this detail

A vertical static fire damper is installed within a fire-resistant-rated wall construction. A duct passes through a required sleeve centered in the partition, with framing maintained with a gap in accordance with manufacturer requirements to achieve a UL-listed assembly. Retaining angles are installed per manufacturer instructions, utilizing double angles only when required for UL compliance. An actuator operates the damper, and an access door is furnished on the side or bottom to allow inspection and servicing. A smoke detector is located within five feet of the damper with no outlet or inlet branches in between, and transition options are provided for various duct configurations.
