AUTOMATIC FIRE SAFETY AND
PROTECTION
Atlas Door Coiling Fire Doors are designed to close
automatically in the event of fire and stop its spread from one area to another for up to
a 4-hour period. Yet these fire-rated doors still can function as Coiling Service Doors.
In its emergency mode, the door's rate of descent is
controlled by a governor. The automatic closing mechanism may be activated by a fire alarm
system, smoke or heat detector, or a melting fuse link 165° F (74° C).
Choose from push-up, chain hoist, crank, or motor-operated.
Type C3 curved slat or type F3 flat slat are available to suit your application. (Refer to
page 6 for slat details.) For smaller applications, please see labeled counter shutters on
page 12.

lengths of painted galvanized steel interlocked to form curtain. Slats are F3 flat (see
pg.6).
***Use either A-Above or A-Below***
A Type: Atlas Door Model (T##GS)Insulated
Coiling Service Door.
1. Thermal Door Slats: assembled of
interlocking cold-formed painted galvanized steel front and back slats. Slats Type T3,
no less than 2-5/8'' (66.68mm) high x 7/8'' (22.23mm) thick, U-Value 0.16 (0.19 W/m2°K)
R-Value 6.25. Environmentally safe CFC-free polyurethane foam-injected to fill all
voids providing continuous insulation protection the full height of the slat.
Insulation self-bonding to the two interior galvanized steel surfaces.
B. Endlocks: each end of alternate slats
fitted with malleable iron endlocks to act as a wearing surface in the guides and to
maintain slat alignment and to prevent flame passage.
C. Gauge: thickness of slat material to
satisfy Underwriters' Laboratories requirements.
D. Galvanizing: zinc-coated in accordance
with ASTM A-653.
E. Bottom Bar: curtain reinforced with a
bottom bare consisting of two steel angles, with lift handles provided on both sides of
door.
2.03 Operation
A. (manual push-up) (chain hoist)
(waist-high crank hoist) (awning crank) (motor -operated).
2.04 Mounting
A. (interior face mounted on a prepared
opening).
***Use either A-Above or A-Below***
A. (interior mounted between jambs and
under lintel in a prepared opening).
2.05 Approval
A. Doors tested and approved by
Underwriters' Laboratories, Inc. (ULI).
B. Label: Doors up to 139
ft (12.9m2) in area and up to 12'-11'' (3937mm)
in width of 12'-0'' (3658mm) in height furnished with ULI Class A (3 -
hour) rating. Doors over these dimensions but less than 1200 ft. (111.5m2)
in area and up to 40'-0'' (12.2m) in width or 30'-0'' (9.1m) in height:
supplied with ULI Oversized Label upon request.
2.06 Automatic Closing
A. Triggering of automatic closing
mechanism by melting of fusible link at 165°F (74°C)
2.07 Spring Counterbalance
A. Counterbalance: housed in a steel pipe
of diameter and wall thickness to restrict maximum deflection to 0.03'' per foot
(2.5mm/m) of door width.
B. Springs: helical torsion type designed
to include an overload factor of 25% and for optimum ease of operation. Springs
grease-packed and mounted on a cold rolled steel inner shaft.
C. Spring Tension: adjustable
from outside of end bracket plate. Upon emergency operation, internal
shaft kicker shall initiate downward travel of door curtain. Spring tension
partially released to induce continued downward travel, door shall retain
sufficient counterbalance to provide assistance with emergency egress.
D. Ball Bearing: sealed, to minimize wear
of pipe shaft rotation around inner shaft.
2.08 Bracket Plates
A. Bracket Plates carrying pipe
counterbalancing shaft no less than 1/4'' (6.35mm) thickness and are to house ends of door
coil. Shape of bracket to be square.
B. Drive End Bracket Plate: fitted with a
sealed ball bearing.
C. Governor: door equipped with a viscous
governor (as required) to control rate of descent.
D. Thru Wall Fusible Link: provide fusible
links on both sides of wall.
2.09 Guide And Wall Angle Assembly
A.Guides/ Wall Angles:structural steel
angles of 3/16'' (4.76mm) minimum thickness.
B. Depth of Guide: shall provide adequate
slat penetration to satisfy Underwriters' Laboratories requirements.
2.10 Hood
A. Hood: to house coil shall
be fabricated of #24 U.S. Gauge galvanized steel. Shape of hood: round.
B. Reinforcing: laterally reinforced to
prevent sag.
C. Intermediate Hood Supports: provide
where door width exceeds 12'-0'' (3658mm).
2.11 Locking
A. (Slide Bolts: on bottom bar for manual
push-up ) (Hand Chain Lock: locking bracket, mounted on guide angle (Locking
Disc: on crank box of crank hoist). (Integral Gearing: of motor
operator)shall provide locking for door.
2.12 Finish
A. Unglavanized Surfaces: shall consists
of a shop coat of rust-inhibiting metallic primer (gray)(brown)on exposed ferrous
surfaces, except bearings. |
