Part 1 General
A. Fire doors excluding design, construction and preparation of opening; finish or field painting; access panels; electrical wiring, conduit, wire, fuses and disconnect switches
1.02 Quality Assurance
A. Certification: Fire doors are labeled or certified by Underwriters Laboratories, Warnock Hersey or Factory Mutual for the hourly rating, wall construction and size allowed by the listing. Fire doors not in compliance with listing requirements are certified by the manufacturer.
Part 2 Products
A. Manufacturing: R & S Manufacturing, model R ___
B. Mounting: Face of wall or between-jamb
C. Operation: Push-up to 8' wide and high and chain hoist on larger sizes is standard; awning crank, crank box or motor operation are optional.
D. Automatic closing: Thermally activated by 165° fusible links, with the closing speed regulated by a governor device operative only during automatic closing.
E. Curtain: Interlocking type ___ slats are roll formed from galvanized steel coil. Gage of slats is as required by the listing. Endlocks are riveted to slats to maintain curtain alignment. Bottom of curtain is reinforced by a double steel angle footpiece.
F. Guides: Steel channels or structural steel angles form curtain guides and are bolted to structural steel wall angles. Sizes of guides are as required by the listing.
G. Brackets: Steel plate brackets are bolted to wall angles to support curtain and barrel and provide mounting for hood.
H. 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 ar mounted on a continuous cold rolled steel shaft, adjustable by a tension wheel outside one bracket.
I. Hood: Formed from minimum 24 gage galvanized steel sheet, reinforced with top and bottom flanges to limit deflection. A thermally released integral flame baffle is provided when required by the listing.
J. Locking: Chain lock with chain operation and slide bolt locks with push-up or crank operation.
A. Slats and hoods are pre-finished with a baked on grey polyester primer before forming. Footpiece, guides and brackets receive one coat of rust inhibiting grey primer.
Part 3 Execution
A. Fire doors are to be installed by an R & S authorized representative in accordance with R & S installation instructions and NFPA 80.
A. Fire doors are to be drop tested and witnessed for proper operation and full closure after installation.
A. NFPA-80 and model code groups mandate annual inspection and testing of fire doors to check for proper operation and full closure.
Smoke Detectors: photoelectric (detects smoke and heat) require connection to a release device with compatible voltage
Release Devices: Electro-thermal and McCabe links (normally open circuits); electro-magnetic and time delay failsafe releases (normally closed circuits)
LiftMaster LM21XPBB Release Device: provides automatic closing and testing of motor operated counter fire doors upon activation by a detector or alarm; eliminates the need for mechanical release and reset unless there is a power loss; allows for a cycling sequence of the door in the event an obstruction is encountered upon closing. See - Fail Safe Devices below.
Perimeter Gasketing: brush seals factory applied to guides and footpiece, field installed on header, to aid in smoke and draft control
Vision Lites: single or multiple 4" wide cut-outs, glazed with clear wire glass (1 1/2 hour rating)
Powdercoat Finish: a durable and decorative finish for steel or aluminum surfaces. It provides longer life and requires less maintenance than a standard finish. Powder coating is available in a variety of colors for use on many products. Consult factory for color selection, applications and limitations.
VIBRATECH ® Viscous Speed Governor: available on R & S Manufacturing, Inc. fire doors for new construction and retro-fit. Viscous speed governor is a patented device allowing for a smooth and quiet descent of fire doors, replaces standard ductile iron governor, and recommended on larger certificate size fire doors, either manual or motorized operation. Viscous speed governor is U.L. listed and conforms to ASTM E152, CAN4-S104, NFPA 252, and UL 10B. Simple, maintenance-free design and construction, with a one year warranty
