PART II - PRODUCT

2.01 MANUFACTURER
Revolving door shall be of types and sizes as indicated on plans, and as manufactured by Horton Automatics, and as supplied by Eastern Door Service, Inc. (800) 390-5521 http://www.EDSDoors.com.

2.02 EQUIPMENT

A. DOOR TYPE
Manual Revolving Door in three or four wing construction

Option: Return-to-Quarterpoint feature.
Option: Electronic Speed Regulator (in lieu of standard mechanical)

B. SPEED CONTROL
The factory set overhead mechanical speed regulator shall be concealed with in the door's canopy.  Floor mounted speed controls are subject to corrosion and damage from water and salt and will not be acceptable.  The mechanical speed control shall prevent the door from operating beyond 12 RPM or the maximum allowable speed as allowed by local codes.

Option: Electronic Speed Regulator
A solid state electronic speed control located overhead shall provide "friction free" rotation up to 2 RPM lower than the governed speed (12 RPM max). An optical sensing circuit shall monitor door speed and apply resistance to door rotation in 3 levels according to door speed. Centrifugal mechanical systems shall not be considered equal. Speed adjusting shall be by simple "volume control" potentiometer speed adjustment not requiring removal or resealing of the speed control mechanism.

C. RETURN-TO-QUARTERPOINT OPTION
Regardless of release position, the door will return to the normal quarterpoint position at a slow speed (1 RPM) and stop. The mechanism shall also assist in the mechanical resistance caused by normal friction surfaces (weatherstrip, door weight). Optional wall safety edges can also be included to stop assisted operation when activated. This feature will not be considered an automatic operator. Door speeds will be kept less than 1 1/2 RPM.

2.03 FINISH
Specify: Anodized or painted aluminum, stainless steel or bronze cladding.

2.04 ENCLOSURE
The enclosure shall be constructed so that proper clearance shall be maintained and weather seal assured.

2.05 DOOR CONSTRUCTION
The 1 3/4" (45 mm) wide, Narrow stile - 2 3/8" (60 mm) or Medium stile - 3 3/4" (95 mm) door wings to be constructed of aluminum extrusions of 6063T5 alloy to ensure frame rigidity and high impact resistance. Horizontal rails on door wings shall have sloped stops. An intermediate muntin bar or pushbar is to be furnished on each wing for safety and division of glass.

2.06 CANOPY
Provide canopy to match contour of the enclosure. (Optional round canopy on segmented enclosure). Canopy sides to be furnished in aluminum panel. Provide aluminum clad plywood .060"/.75" - (1.5/19 mm) for interior ceiling. Optional: Exterior roof fabricated from .090" - (2 mm) anodized aluminum.

2.07 HARDWARE/WEATHERSTRIPPING
Door wings shall be provided with manufacturer's standard muntins or pushbars. Provide locks with five pin cylinders and concealed bolts. A sweep shall be affixed to each wing to provide adequate weatherstripping and ensure weatherseal. Lower shaft bearing shall be surface mounted not requiring excavation beneath the floor line.

2.08 CEILING LIGHTS (OPTIONAL)
Furnish two ceiling lights with energy efficient lighting systems with flush lens.

2.09 GLASS

A. ROUND DOOR:
Wings: 1/4" (6 mm) tempered
Walls: 7/16" (12 mm) laminated safety glass

B. SEGMENTED DOOR:
Wings: 1/4" (6 mm) tempered
Walls: 1/4" (6 mm) tempered

Segmented walls and wing system can accommodate up to 1" (25 mm) glazing.

2.10 REQUIREMENTS FOR ELECTRICAL WORK BY OTHERS
The Electrical Contractor shall furnish and install all wiring to speed control. Provide 120 VAC, 60 cycle, 1 phase, 15 amp service to each speed control (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.

NOTE: Maximum current draw is 5 amps per speed control protected by internal circuit breaker in speed control.

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.
