Service Doors Specifications and Options

Specifications

Part 1 General
1.01 Summary
A. Service doors excluding design, construction and preparation of openings; finish or field painting; access panels; electrical wiring, conduit, wire, fuses and disconnect switches

1.02 Performance
A. Windload: Service doors are designed to withstand a minimum 20 PSF windload. (1)
B. Usage: Service doors are designed to operate a minimum of 20,000 cycles. (2)

Part 2 Products
2.01 Materials
A. Manufacturer: R & S Manufacturing, model D___
B. Mounting: Interior or exterior face of wall or between-jamb
C. Operation: Chain hoist is standard; push-up (small sizes), awning crank, crank box or motor operation are optional.
D. Curtain: Interlocking type___ slats are roll formed from galvanized steel coil. Gage of slats is as required to meet windload. Endlocks are riveted to slats to maintain curtain alignment. Windlocks are riveted to slats when required to meet windload. Bottom of curtain is reinforced by an extruded aluminum or double steel angle footpiece with astragal.
E. Guides: Steel channels or structural steel angles form curtain guides and are bolted to structural steel wall angles. Sizes of guides are as required to retain curtain under windload. Windlock bars are provided when windlocks are required to meet windload.
F. Brackets: Steel plate brackets are bolted to wall angles to support curtain and barrel and provide mounting for hood.
G. Barrel: Minimum 6" diameter steel pipe houses torsion spring assembly and supports curtain with a maximum deflection of .03 inch per foot of width. Torsion springs are mounted on a continuous cold rolled steel shaft, adjustable by a tension wheel outside one bracket.
H. Hood: Formed from minimum 24 gage galvanized steel sheet, reinforced with top and bottom flanges to limit deflection. Intermediate support is provided when required.
I. Locking: Chain lock with chain operation and slidebolt locks with push-up or crank operation.

Part 3 Execution
3.01 Installation
A. Service doors are to be installed by an R & S authorized representative in accordance with R & S installation instructions.

Options

Increased Windload Capacity: curtain designs to withstand windloads exceeding 20PSF
High Cycle Construction: designs to provide up to 150,000 operating cycles or maximum possible in design
Perforated Slats: 3/64" diameter holes on 5/64" staggered centers in type 25 slats provide 30% open area for ventilation and visibility throughout the curtain
Vision Lites: single or multiple 3" wide cutouts, open for ventilation or covered with acrylic
Intermediate Grille: partial grille curtain connecting type 30 slats above and below
Sloped or Stepped Footpiece: for special sill conditions
Cylinder Locks: on footpiece or guide
Pass Door: 3'-0"x6'-8" hollow metal door in a steel frame for access through the curtain when closed; frame is hinged to guide and swings clear to allow use of entire door opening when curtain is raised; handicap option, custom sizes, windows and special hardware available
Galvanized Finish: on footpiece, guides, brackets and barrel
Special Accessories: See Special Accessories Page
Powdercoat Finish: on curtain, footpiece, and guides

(1) Standard design will allow the rolling door to be operable after having been subjected to a uniform constant load of 20 PSF. Curtain slat deformation may occur and there is no guarantee of operability while under load unless such a requirement is stated by the specifier. Windload forces acting on the rolling door slats may cause severe loadings at the jambs. The building door jamb construction (walls, steel structure, etc.) must be designed to withstand the anticipated loads.

(2) Frequency requirements must specify for the door operator and all components a fixed number of cycles for an expressed period of time and include a sealed counter device. A cycle is defined as an action on the door from fully closed, to the fully open, and returned to the fully closed position.
