2.2	ROUND COMBINATION FIRE SMOKE DAMPERS

A.	Model: FDR-500 and SSFDR-500 series true round static rated fire dampers.
B.	Ratings:

1.	Fire Resistance: 
************************************************************************************
Specifier Notes: UL 555 provides for classification of combination fire smoke dampers with fire resistance ratings of either 1 ½ or 3 hours.  NFPA 90A requires that HVAC penetrations through barriers with fire resistance ratings less than 3 hours be protected by 1 ½ hour rated dampers.  Penetrations through barriers with fire resistance ratings of 3 hours or more require 3 hour rated dampers.  NFPA 90A also requires that all combination fire smoke damper locations and their hourly rating requirements be shown on the project plans.  Specifier, select from the following:
************************************************************************************
•	Dampers shall have a UL 555 fire resistance rating of 1½ hours. 

2.	Fire Closure Temperature: 
Each combination fire smoke damper shall be equipped with a factory installed heat responsive device rated to close the damper when the temperature at the damper reaches:
************************************************************************************
Specifier Notes: NFPA 90A requires fire dampers to close by the action of a heat responsive device (usually a fusible link) when temperature at the damper reaches a certain temperature. The minimum temperature established by NFPA 90A is 165oF. Most damper manufacturers offer 165oF and 212oF. Some building codes may require 165oF, but if allowed by the applicable code, 212oF is the recommended choice. Be sure to verify availability of any temperature other than the following options. Specifier, select one of the following options. 
************************************************************************************
•	165F
•	212F

B.	Construction:
1.	Frame and Sleeve: 
•	The damper frame and sleeve shall be of one piece design, made with 20 ga. galvanized steel and a groove for added strength (FDR-500 series).
•	The damper frame and sleeve shall be of one piece design, made with 20 ga. 304 stainless steel and a groove for added strength (SSFDR-500 series).

2.	Blades: 
•	Single skin, minimum 20 ga. equivalent thickness, galvanized steel
(FDR-500 series).
•	Single skin, minimum 20 ga. equivalent thickness, 304 stainless steel (SSFDR -500 series).

3.	Axles: 
•	Minimum ½ inch dia. plated steel.

4.	Bearings: 
•	Axle bearings shall be bronze sleeve type (FDR-500 series).
•	Axle bearings shall be 304 stainless steel sleeve type (SSFDR-500 series).

5.	Fire Closure Device:
•	Dampers shall be supplied with fusible link.

6.	Mounting:
•	Vertical
•	Horizontal

7.	Retaining Plates:
************************************************************************************
Specifier Notes:  Single Retainer plate is required on either side of the wall/floor installation. Second retaining plate can be used but, not required. Specifier, select one of the following
************************************************************************************
•	Single 
•	Two

8.	Finish:
•	Galvanized steel (FDR-500 series)
•	304 stainless steel (SSFDR-500 series)

2.3	SOURCE QUALITY CONTROL

A.	Factory Tests: Factory cycle damper and actuator assemblies to assure proper operation.

PART 3   EXECUTION

3.1	EXAMINATION

A.	Examine areas to receive dampers.  Notify the Engineer of conditions that would adversely affect installation or subsequent utilization of dampers.  Do not proceed with installation until unsatisfactory conditions are corrected.

3.2	INSTALLATION

A.	Install dampers in accordance with manufacturer’s UL Installation Instructions.  Any damper installation that is not in accordance with the manufacturer’s UL Installation Instructions must be approved prior to installation. 

B.	Dampers must be accessible to allow inspection, adjustment, and replacement of components.  The sheet metal contractor shall furnish any access doors in ductwork or plenums required to provide this access.  The general contractor shall furnish any access doors required in walls, ceilings, or other general building construction.  

C.	Install dampers round and free from racking. 

D.	Do not compress or stretch the damper frame into the duct or opening.

E.	Handle dampers using the frame or sleeve.  Do not lift or move dampers using blades, actuator or jackshaft.

F.	Install connections to [electric, pneumatic] actuators as specified in section 230913.
