Specifications
ROLLING security CLOSURE SYSTEM:
A. Rolling Security Closure System: Shall be Rolling Grill Debonaire model.
B. Curtain: Constructed of 2-1/2” high on center horizontal sections of full width,
concealed 5/16” diameter rods spaced with 9” wide, horizontally interlocking
extruded aluminum panels arranged in a checkerboard pattern.
C. Support Structure: 3” x 3” or 4” x 4” steel structural tubes with 14 gauge or greater
wall for between jamb site conditions or 2” x 3” steel angles for face-of-wall site
conditions are to be provided.
D. End Plates: Furnish steel plates not less than 3/16” thick (with dimensions
appropriate to coil size) to support the ends of the barrel assembly with sealed, selfaligning
shaft bearings. End plates bolted to support tubes.
A. Barrel: Minimum 6-5/8” diameter x 0.156” wall steel pipe barrel will be designed to
carry curtain load with a maximum allowable deflection of 0.03” per foot of closure
width. Barrel to house a torsion spring counter-balance assembly to counter-balance
the curtain.
Counter Balance: Oil tempered, helical torsion spring(s) pre-lubricated and
secured around a continuous, solid, cold rolled steel inner shaft will act as
counter balance within barrel. Shaft will bear on self aligning, permanently
lubricated ball bearing assemblies. Counterbalance assembly to be designed
for a minimum life of 20,000 cycles. Spring to be site tensioned by attached,
accessible charging wheel.
B. Manually Operated: Standard closure to be manually operated push up, pull down
with removable retrieval rod as standard. The effort to raise or lower the grille shall
not exceed 15 pounds force. Optional hand chain hoist, hand crank (with removable
crank handle) or electric motor operation is available. Closures over 16 feet wide will
be electrically operated.
C. Electric Motor Operator: Motor operator shall be industrial duty, jackshaft hoist type.
Primary reduction shall be heavy-duty belt drive with chain-and-sprocket secondary
reduction. Mechanism is to be self-locking when torque is applied to output shaft.
Operator shall have an adjustable, torque limiting friction clutch.
1. Motor: Shall be a continuous-duty, high starting torque motor with instant
reverse and current sensing or thermal type overloads Protection. Standard
motor shall require 115 VAC., single phase, 60 Hz. Motor controller shall be a
heavy duty, full voltage, across-the-line, magnetic reversing contactor that is
mechanically and electrically interlocked. Electrical components shall be
installed in NEMA 1 enclosure integral to the operator. A transformer shall
provide 24 VAC. secondary power to the control station (s).. Positive chain
drive, rotary type limit switches shall be provided to limit full open and close
travel of the door. A manual hand chain is provided to enable the grille to
opened and closed in case of power outage. The operator shall be capable of
right or left hand mounting.
2. Built-in Interlock: The motor operator shall have a built-in interlock that will
prevent the grille from being damaged if operated electrically when in the
locked position.
3. Electric Key Switch: Control station (when applicable) shall be two position,
open/close, constant pressure type for flush mounting, housed in a tamperproof
enclosure.
4. Emergency Egress Device: If required, supply a manually activated
emergency egress device to facilitate egress from the space.
D. Guides: Vertical curtain guides are to be of extruded aluminum 1 3/4” wide x 2-1/2”
deep.
E. Bottom Bar: Heavy duty extruded aluminum section, bell-shaped to provide
reinforcement. Bottom bar to house lock mechanism. Underside of bottom bar shall
be removable to allow service or replacement of lock mechanism.
F. Locking: Center lock mechanism to be Adams-Rite 2-point deadlock which activates
3/8” steel lock bars at each end. Standard mortise cylinders operable from both
sides, mall side only, or tenant side only. Removal of bottom bar not necessary to
change the cylinders.
G. Cylinders: Locking bottom bar (when applicable) to be equipped with standard 1”, 5
pin mortise cylinder.
H. Aluminum Extrusion Finish: Standard anodized finish shall be clear natural
anodized. Special anodized and painted finishes are available upon request. Consult
manufacturer for pricing and lead times.
I. Aluminum Extrusion Material: 6063-T5
EXECUTION
INSPECTION:
A. Verify that the rolling security closure system will not disrupt other trades. The
installer shall verify that the installation area is dry, clean, and free of foreign matter.
Verify that the opening dimensions are as shown on Dynaflair’s shop drawing(s)
prior to proceeding with the installation. Check condition of pre-installed vertical grille
guides for damage or pinching by recessing materials or other trade’s fasteners
driven into guide extrusions.
INSTALLATION OF ROLLING SECURITY CLOSURE SYSTEM:
A. Installation shall be by an installer approved and trained by the manufacturer in strict
accordance with installation guide.
B. Explain and review the correct locking, operation and maintenance of the rolling
security closure system.
C. Installation of any motor operators, control switches and related wiring shall be by a
locally certified electrician and shall be in strict accordance with local building codes.
