PART II - PRODUCT
2.01 MANUFACTURER
Automatic bifolding door shall be (1) Series 4-4200 or (2) Series 4-7200
type(s) and size(s) as indicated on plans and, as manufactured by Horton
Automatics, a division of the Overhead Door Corporation and as supplied by Eastern Door
Service, Inc., Florence, NJ (800) 390-5521 http://www.EDSdoors.com.
2.02 EQUIPMENT
A. OPERATOR
Operator shall be (1) heavy duty, self-contained,
electromechanical Series 4000. The operator shall be powered open with a 1/8 HP DC
permanent magnet motor working through reduction gears to the output shaft. Closing force
shall be supplied by a field replaceable QuadraCoil™ spring (four independent
coil springs separated by Teflon™ discs and enclosed in an external spring
box).
The Series 4000 operator shall be shock-mounted and
concealed in a 6"x6" (152mm x 152mm) extruded aluminum side-load housing with a
removable faceplate, not less than 1/8" (3mm) thick. Housing shall extend the full
width of the door unit less the endcaps and jambs.
Shall be (2) low-force, self-contained, electromechanical Series
7000. The operator shall be powered open with a DC motor working through six reduction
gears. Closing shall be by spring force. When the door is in the closing mode or fully
closed, motor voltage shall not be required and will be off. The door can be manually
operated with power on or off without damage to the operator.
The Series 7000 operator shall be mounted and concealed in a
4"x6" (102mm x 152mm) extruded aluminum housing with a removable faceplate, not
less than 1/8" (3mm) thick. Housing shall extend the full width of the door unit less
the jambs.
The master control shall include the following variable adjustments:
Opening Speed— 80° of door travel to Open Check per 1.5 to 10
seconds.
Closing Speed— 80° of door travel to Close Check per 3 to 10
seconds.
Closing force (with door in stalled condition and measured from
full-open to within 2" (50mm) of full-closed) should not exceed 30 lbfs. (133 N) of
force to stop the door when operating in closing direction.
The control shall provide for immediate reversal of door motion
without undue strain on the drive train by supplying stepped voltage to the motor. The
door shall reverse when closing if an object stops the door. A locked-door, motor
protection circuit will be supplied that will shut-off current to the motor if it is
applied when the door is inadvertently locked or otherwise prevented from opening.
B. DOOR UNITS
Shall be: (1) Series 4-4200 or (2) Series 4-7200 and include
electric operator(s) and control(s), aluminum housing with removable faceplate,
breakout/track mechanism, top roller guide, top pivot, bottom pivot, folding (hinged) door
panels, threshold, jambs, and if applicable, transom and sidelites. All structural
aluminum sections shall be 6063-T5 Alloy with safety radius corners on all vertical rails.
When the doors are in the open position, they shall provide
a net opening of approximately 77-83 percent of the inside frame opening width.
The header shall be constructed to conceal the
operating mechanism while the breakout/track mechanism is secured to the underside of the
header. The folding action of the door panels is accomplished with a top roller guide
secured to the inactive door panel that slides in a track extruded as part of the breakout
system. Both the top roller guide and breakout mechanism are replaceable. One folding
panel closest to the jamb (active panel) shall be connected to the automatic swing
operator at the top pivot and set on a floor mounted bottom pivot assembly. No bottom
track shall be required.
All panels shall be equipped with a safety radius nosing that
incorporates an astragal with adjustable mohair weatherstripping. Joining vertical panel
rails shall have double weatherstripping of mohair type fabric. Hinge points are protected
with a 1" (25mm) Santoprene™ filler for both seal and safety. Door panel
construction shall be tongue and groove key fitting gussets with two tempered bolts in
each corner section to assure against racking failure.
In an emergency, the bifold door(s) shall swing-out (breakout) by
applying a pressure not to exceed 50 lbfs. (222 N) force measured at the lock stile. It
shall breakout from any position in the door's travel. Power to the operator shall be
disconnected when the door panels are in this emergency breakout position.
C. FINISH
OPTIONS: All exposed surfaces shall be (Select desired finish)
1) 204-R1 clear anodized aluminum.
2) 313-R1 dark bronze anodized aluminum.
3) Manufacturer's standard two coat Duranar finish. Color to be selected by architect from

four panels, with two panels folding to each side of opening.
E. HARDWARE
Folding panel shall have Adams Rite Maximum Security Lock.
OPTION: Automatic Electro-magnetic Locking
2.03 CONTROL SWITCHES
Provide a complete safety/activating system of the type specified
herein as shown on the drawings.
Safety System: A safety zone of a minimum
length 5" (127 mm) greater than the door width in the open position shall be provided
on the swing side of the door to either prevent the door from opening or hold the door in
the open position when the swing area of the door is occupied.
A. SAFETY SYSTEM
Provide BEA model BodyGuard active infra-red
presence sensor at folding side of door units.
The infra-red presence sensor shall provide presence detection
through the door's threshold area, when the door is in the open position.
B. ACTIVATING DEVICES
Provide BEA model Eagle
motion sensor with pattern suitable
for door opening size shall be installed on the approach side of the door.
C. GUIDE RAILS
Shall be furnished on the fold-side of door to protect cross-traffic.
2.04 REQUIREMENTS FOR ELECTRICAL WORK BY OTHERS
The Electrical Contractor shall furnish and install all wiring to operator.
Provide 120 VAC, 60 cycle, 1 phase, 15 amp service to each operator (header) on a separate
circuit breaker routed into header. Remote switches (if specified) shall be provided with
control wire and electrical boxes from switches to operators. Remote switches provided
under this section shall be installed by the electrical contractor.

operator.
PART III - EXECUTION
3.01 INSPECTION
Installer must examine the areas and conditions under which automatic doors are to be
installed and notify the Contractor in writing of conditions detrimental to the proper and
timely completion of work. Do not proceed with the work until all unsatisfactory
conditions have been corrected in a manner acceptable to the installer and in accordance
with approved shop drawings.
3.02 INSTALLATION
Comply with specifications and recommendations. Set track and operator plumb, level and
true to line, without warp or rack of doors. Anchor securely in place. Isolate aluminum
and other corrodible materials from sources of electrolytic action at points of contact.
Install complete door operator system in accordance with manufacturer's instructions,
including drive mechanism, controls, and control switches.
3.03 ADJUST AND CLEAN
Adjust operator and controls for optimum condition and safety. Lubricate operating
equipment. Clean surfaces promptly after installation, exercising care to avoid damage of
the protective coating (if any). Advise contractor of protective treatment and other
precautions required through the remainder of the construction period, to ensure that
doors will be without damage or deterioration (other than normal weathering) at the time
of acceptance.
