• FIRE DAMPER
:A Device used to restrict the passage of flame through the duct work
of an air system. A fire damper is installed in fire rated wall or floor &
closes automatically to maintain the integrity of that partition.

•Combination Fire & Smoke Dampers combines the smoke sealing capabilities of a
standard smoke damper with the high temperature
capability of a fire damper. These dampers are tested in
accordance to UL555 and UL555S

• Smoke dampers are motorized
with either an electric or
pneumatic actuator. They are
controlled by smoke or heat
SMOKE DAMPERS
controlled by smoke or heat
detector signal, fire alarm or some
other building control system.

Fire Endurance / Hose Test• The damper is exposed to a prescribed and regulated
fire for either 1-1/2 or 3 hours to determine hose the hourly classification of the damper assembly. Immediately after the fire exposure, the damper is hose down with a heavy stream of water. This provides an extreme shock to the damper ensuring it will withstand the severity of all fire conditions.
