The number of fire dampers in an installation
opening is limited by their damper size
(Æ nominal width) and the overall area of the fire dampers (4.8 m
2
).
The dampers can be arranged in one or two rows.
Structural properties of the ceiling construction,
including the attachment to the mortar/concrete or
any required reinforcement, have to be evaluated
and ensured by others.
