Model 1290F fire damper is 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 1290F is classified for use in dynamic "fans
on" systems where the HVAC system remains operative in the
event of a fire. Damper closure under airflow is assured.
The 1290F is an economical true round fire damper designed
and qualified specifically for point-of-origin fire containment
where round ductwork passes through metal or wood stud
drywall partitions and masonry walls or floors.
Features include the industry proven over-center knee lock
design with high torque spring/fusible link closure. The 1290F is
supplied as standard with a crank arm and locking screw which
holds the damper in the fully open position, but may also be used
for system balancing if required.
STANDARD CONSTRUCTION:
Frame: 20 ga. (1.0) galvanized steel integral sleeve and
retaining plates.

Model 1290F-SS fire damper is ideal for high humidity or mildly
corrosive 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 1290F-SS is
classified for use in dynamic "fans on" systems where the HVAC
system remains operative in the event of a fire. Damper closure
under airflow is assured.
The 1290F-SS is a true round fire damper designed and qualified

Features include the industry proven over-center knee lock design
with high torque spring/fusible link closure. Supplied as standard
with a crank arm and locking screw which holds the damper in the
fully open position, but may also be used for system balancing if
required. Available in either Type 304 or 316 stainless steel.

APPLICATION:
• The MLS-300 Position Indicator Package operates as a function
of the damper blade position and provides the ability to remotely
indicate damper blade position.
• The MLS-300 incorporates two SPDT switches and provides a
positive open or closed signal when used in conjunction with
remote indicator lights. MLS-300’s are used in active smoke
control management systems to positively indicate the status of
all combination fire/smoke and smoke dampers in the building.
• The MLS-300 is available only as a factory installed option on
combination fire/smoke and smoke dampers.
• The MLS-300 may also be used to provide a stop/start circuit
for remote fans or to signal alarms.
