Features:
• The EFNA series Combination Fire/Smoke Dampers have been
designed and tested to exceed all UL, ULC and NFPA requirements for fire dampers as well as smoke dampers.
• EFNA is UL 555 and ULC S112 listed and labeled as a 1-1/2
hour fire damper and a 3 hour fire damper.
• UL and ULC listed for both vertical and horizontal
mountings.
• UL 555S / ULC S112.1 listed and labeled as a
Leakage Class I rated Smoke Damper with airflow in both
directions. Class I provides for a max. leakage of
8 cfm per sq. ft. at 4.0 inches static pressure.
Notes:
• Non-sleeved dampers with side plate are furnished approximately
1/4” smaller than given duct dimensions. Sleeved dampers are
furnished approximately same size as given duct dimensions,
unless otherwise noted.
• It is recommended the damper must be inspected and cycled at
intervals not greater than every twelve months or in accordance with
NFPA 80, 90A, 92A, local codes and the actuator manufacturer.

Model EFNA - Combination Fire/Smoke Damper, Class I

When the actuator is externally mounted and the wall thickness exceeds 5 inches, add 1
inch for each additional inch
of wall thickness increased to
ensure sleeve length through
the penetration. As standard
the actuator is externally
installed on the lower right
hand half of the damper when
viewed from the jackshaft
side. The damper may be
installed/rotated 180° such
the actuator will be located on
the upper left. The top of the
damper is either side of the
frame as long as the blades
are running horizontal. When
ordering internally mounted
actuators, be aware there is a
min. height requirement (in
some cases the sleeve can
be increased to allow for internally mounting). The entire
damper frame does not have
to be installed in the plane of
the wall or floor. The rule of
thumb is with the damper in
the closed position, the blade
plane should be within the
plane of the UL rated wall or
floor.
