The 1200 Series Dampers are ideal for applications where building codes
require a fire damper for the protection of ductwork penetrations in walls or
floors that have a fire resistance rating of up to 2 hours.
The 1200 Series is classified for use only in static "fans off" systems where
the HVAC system is automatically shut down in the event of a fire alarm.
The 1200 Series has been especially designed and tested to provide
premium performance. Airfoil blade design and elimination of blade sills,
top and bottom, provide a low pressure drop design.
The 1200 Series features the industry proven over-center knee-lock
design with high torque spring/fusible link closure.
Unique, inter-locking double skin blade design provides flame and smoke
seal under fire conditions.
The 1200 is supplied as standard with an internal locking quadrant which
holds the damper in the fully open position, but may also be used for
system balancing if required.
