1. SMOKE DAMPER REQUIREMENTS AND APPLICATION
Smoke dampers are required to close and prevent
the passage of air and smoke through ducts or ventilation openings in smoke barriers. Smoke dampers are also applied in engineered smoke control systems to establish air pressure differentials and thereby prevent the spread of smoke. These dampers are designed to operate with blades running horizontally. Dampers can be vertically or horizontally installed at, in accordance with NFPA-90A, or adjacent to the point where the duct passes thru the smoke barrier.
2. LOCATION OF DAMPER IN DUCTWORK
Place the damper assembly in its proper position
relative to the barrier. The plane of the closed damper blades must be within 24 in. (610mm) of the rated smoke barrier and before any duct inlets or outlets.
3. ATTACHING DAMPER TO THE DUCT
The damper is flange mounted to the duct, sleeve,
or wall opening with using #10 sheet metal screws, 1
/4 in. (6mm) diameter bolts and nuts, tack or spot welds, or 3/16 in. (5mm) diameter steel pop rivets. Attachments must be made at each flange spaced a maximum of 6 in. (152mm) on centers and a maximum of 2 in. (51mm) from corners.
4. SEALING THE INSTALLATION
The following duct sealants may be used to seal
between the dampers flange and the mating surface: PA2084T duct sealant adhesive manufactured by Precision, DP1010 water base duct sealant manufactured by Design Polymetrics, Grey Pookie or Ductmate PROseal® in accordance with SMACNA recommendations.
5. ACTUATOR CONNECTIONS
Electrical and/or pneumatic connections to damper
actuators should be made in accordance with wiring and piping diagrams developed in compliance with applicable codes, ordinances and regulations.

FAN ISOLATION APPLICATION
For air handling equipment isolation, leakage rated dampers are designed to operate with blades running horizon-
tally. Dampers can be installed in a vertical or horizontal position. Sealants and damper seal materials meet the requirements of NFPA90A for smoke developed rating (<50) and flame spread index (<25) as tested per UL723/ ASTME84-91A/NFPA 255. Dampers can be attached to the fan system discharge or inlet without being 24 in. (610mm) of a smoke barrier when used as an air handling equipment isolation damper.
