Features:
• The EGPA 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.
They are intended for use where building codes call for the
fire damper to also operate as a smoke damper.
• EGPA is UL 555 and ULC S112 listed and labeled as a 1-1/2
hour fire damper.
• UL and ULC listed for vertical mounting.
• UL 555S / ULC S112.1 listed and labeled as a Leakage
Class II rated Smoke Damper with airflow in both directions.
Class II provides for a max. leakage of 20 cfm per sq. ft. at
4.0 inches static pressure. As we are constantly expanding
our UL / ULC listings, we suggest you contact the factory for
current information.
Suggested Specifications:
The EGPA damper is UL / ULC qualified for mounting outside of
the plane of the wall and have concealed actuator access, from
grille side, to allow through the grille access to actuator and
controls.
Notes:
• Sleeved dampers are furnished approximately same size as given
duct dimension plus 3/8” for insulation, unless otherwise noted.
• *Wall opening must be oversized by 3/4” to accommodate thermal
blanket thickness.
• Not recommended with blades running vertically.
