The engineer has submitted a drawing that is four townhouse style units. As designed, the walls are supposed to be sufficient to treat each unit as an individual and not require any fire dampers. The GC has stated that walls are not rated as such and fire dampers will be required and the rated assembly is an L528. The L528 assembly has no listed fire dampers that could be used to protect the floor register penetrations and I cant seem to get the engineer to understand this. Their last response was "Any type B damper will work". Does naybody know of or have an example of a fire damepr being used to protect a floor register penetration. Or anything else to add?
