Smoke Dampers. Installation Instructions

Transcription

1 Smoke Dampers Installation Instructions Installation Details 1. Dampers should be installed to provide proper operation and performance. They should be installed to permit them to maintain their shape and remain square. Do not compress or stretch damper frame. Damper should be installed as to prevent any racking. 2. The dampers should be attached to the duct (s), sleeve or wall opening using No. 10 sheet metal screws, 1 /4" dia. (6 mm) bolts and nuts, 1 /2" (13 mm) long welds, spot welds or 3 /16" (5 mm) dia. steel pop rivets, 12" (305 mm) on center with a minimum of three fasteners. As well, when dampers are installed as a multiple damper assembly, the damper frames should all be attached to each other as outlined above. 3. All joints where the damper frame meets the duct or sleeve should be sealed using a 1 /8" (3 mm) bead of sealant - CGE1200 Silicone Construction Sealant. As well, when dampers are installed as multiple damper assembly, all joints between the damper frames should be sealed as outlined above. Smoke dampers must be installed at or adjacent to the point where the duct passes through the smoke barrier in accordance with NFPA 90A. The maximum installation distance is 24" (610 mm) from the smoke barrier, however, the preferred location of leakage rated smoke dampers is in the smoke barrier. Duct air outlets, inlets or branches shall not be located between the smoke damper and the smoke barrier. Smoke dampers must not be installed in fibrous glass-lined ducts and fibrous glass ducts in a manner that will damage the material. Use a hat section standoff, lining interruption, metal sleeves or sections on externally insulated metal duct. Provide a duct hanger at a smoke damper location when the duct strength is inadequate for the damper and its operator. If the damper operator is located within the duct, an access door must be provided. Manufacturer s Recommendations All moving parts of the damper must be inspected and cycled at intervals not greater than every six months and in accordance with the latest edition of NFPA 90A, 92A, local codes and the actuator manufacturer. In addition, fuse links shall be removed and inspected for corrosion. Dry lubricants are recommended.

2 Accessories & Options Actuator and Jackshaft Dimensions NOTE: Dampers are intended to be selfsupporting only in the largest recommended single sections. Multiple assemblies may require additional bracing. PRICE Manufacturing recommends appropriate bracing on multiple assemblies at over 8' (2438mm) of width and height. JACKSHAFTING: STANDARD CONTRUCTION 1. Bearing support bracket. Located at either end of assembly and at each vertical mullion. 2. Lever arm attached directly to blade axle to maximize torque transfer. 3. Either 1 /2" (13 mm) diameter solid steel rod or rod + 3 /4" (19 mm) diameter steel pipe (depending on dampersize, static pressure, etc.) 4. Pivot arm of heavy gauge steel and attached to rotation bar (No. 3) with steel bolts. 5. Operator arm for connection to motor operator. (Required for internal motor mount.) 6. Ball bearings. Manufacturer s Recommendations All moving parts of the damper must be inspected and cycled at intervals not greater than every six months and in accordance with the latest edition of NFPA 90A, 92A, local codes and the actuator manufacturer. In addition, fuse links shall be removed and inspected for corrosion. Dry lubricants are recommended. Jul / SHEET 1 OF 1

4 Accessories & Options Damper Operators Both electric and pneumatic damper operators are available from PRICE Manufacturing and may be factory installed (see methods below) with either our SCD, SSD & FSD series control dampers, smoke dampers, and combination fire/smoke dampers. We are constantly expanding our Underwriters Laboratories listings and therefore recommend that you contact the factory for the appropriateness (i.e. size limitations, torque, and temperature) of a given fire/ smoke application. Control dampers may be shipped with factory installed motors provided we have the following information: 1. damper/duct size; 2. maximum velocity; 3. maximum static pressure; 4. application (shut-off, balancing, or modulating damper); 5. location of operator (internal or external); 6. pneumatic or electric system. Suggested Specification Manufacturer s Recommendations All moving parts of the damper must be inspected and cycled at intervals not greater than every six months and in accordance with the latest edition of NFPA 90A, 92A, local codes and the actuator manufacturer. In addition, fuse links shall be removed and inspected for corrosion. Dry lubricants are recommended. Typical Installation: Dampers may be furnished with-out an operator but with an extended shaft for on site attachment to motor. Dampers may be furnished with factory installed mounting plate (insert type: designation IT) either with operator or extended shaft for on site attachment. Operator mounted out of airstream. Dampers may be furnished with operators mounted inside duct with factory installed internal motor mount. Dampers may be furnished with factory installed sleeves and with operators mounted outside or inside air stream. Minimum sleeve depth 16" (406mm). Jul / SHEET 1 OF 1

5 Model M/S for Combination Fire/Smoke Dampers Micro Switch Package The M/S Switch Package provides the ability to remotely indicate the damper blade position. It is two integrally mounted micro switches for positive status indications. Electrical interface with a remote control on/ off fan station is also possible with the M/S package. The M/S Switch Package consists of the switch box, containing two damper position indicator switches (one closes when the damper is fully open and the other closes when the damper is fully closed), a switch box mounting bracket, a blade bracket, and hardware necessary to directly link the switch box to the blade.
