SYSTEMS
Nailor’s 1200 Series multi-blade fire damper 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 utilizes an innovative inter-locking double skin airfoil blade
design that maintains a complete barrier throughout the fire test with absolutely no visible through-gaps. Amazingly, the 1200
Series fire damper gets tighter as it gets hotter! Ideal for use where building codes require a fire damper for the protection of
ductwork penetrations in walls or floors, Model Series 1200 has a 1 1/2 hour UL label suitable for use in separations with fire
resistance ratings of less than 3 hours. Features include a unique airfoil blade design and maintenance-free concealed blade
linkage for extremely low pressure drop and minimal turbulence and noise. Rugged hat-channel frame is reinforced with die-
formed corner gussets for superior rigidity. Industry proven high torque spring/fusible link with over-center knee lock design
provides the security of assured closure under fire condition. Supplied as standard with an internal hand locking quadrant to hold
blades in open position or balance the system, the 1200 Series is available with factory fitted sleeve ready for installation and
choice of transition styles to suit duct size and type.
