• Access to Fire Smoke Dampers - often the exact position is unknown until late
• Restricted Access for maintenance
• The position of the actuator is difficult to establish during stage 4 because the Fire Strategy is still ongoing and the equipment selection often changes, therefore the motor may end up on the wrong side of the wall.
• The below normally causes issues late in the project with ceilings being required to be dropped as architects unaware that the damper has to be supported independently, in its own hole and 75mm from any wall or ceiling.
  • Separation distances between fire dampers & between fire dampers & construction elements * EN1366-2:2015 references separation distances as; 200mm between fire dampers installed in separate ducts.*
  • 75mm between fire damper and a construction element (wall/floor) – e.g. for a damper in a wall, this is the distance between the damper casing (largest dimension) mounted in the supporting construction and a wall or floor adjacent to that supporting construction.*
  • Structural openings* A fire damper should normally be installed in its’ own unshared structural opening. Not shared with other dampers or other services.* </aside>
