A Curtain Design:Rolling Grill-PP “Perforated Panel”
1. Constructed of 3” on center extruded aluminum sections. Each section
framed with continuous, double “C” hinge with 2-1/2” wide 16 gauge
perforated metal panels at 16” horizontal intervals.
B. Support Structure:
1. Supports: 3 inch X 3 inch or 4 inch X 4 inch structural tubes with 0.120 wall
thickness furnished by us to be pre-drilled and tapped for guides and
endplates. Tubes to be attached to the floor slab and joists above. Attachment
at top is for lateral support only. Provide 2 inch X 3 inch steel angles for face
of wall installations.
C. 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, self-aligning shaft
bearings. End plates bolted to support tubes.
D. 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.
E. 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.
F. 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.
G. 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 tamper-proof
enclosure.
4. Emergency Egress Device: If required, supply a manually activated emergency
egress device to facilitate egress from the space.
H. Guides: Vertical curtain guides are to be of extruded aluminum 1 3/4” wide x 2-1/2”
deep.
I. 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.
J. 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.
K. Cylinders: Locking bottom bar (when applicable) to be equipped with standard 1”, 5
pin mortise cylinder.
L. 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.
M. 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 preinstalled
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.
