2.02 AUTOMATIC OVERHEAD CONCEALED SYSTEM

A.        GT Model 300 SWING UNIT as indicated on door schedule and details.

B.        Mode of operation: Spring Close. Gyro-Swing operator shall open door by energizing motor and shall stop door by electrically reducing voltage and stalling motor against mechanical stop. Door shall close by means of spring energy, and closing force shall be controlled by gear system and motor being used a dynamic brake without power. System shall operate as a manual door control in event of power failure. Manual operation shall require less than 50lbs. force applied to door stile. Opening and closing speeds shall be adjustable. Door operation shall not require any fluids or gases under pressure to be used in opening and closing of door.

C.             Components:

1. Operator Housing

2. Gyro-Swing Power Operator

3. Electronic Control

4. Connecting Hardware

5. Breakaway Door Stop

1a)       Operator Housing: GYRO TECH Housing shall be 5-1/2" (139.7mm) wide by 5" (127.0mm) high aluminum extrusions with enclosed end caps for application to 4" (102.6mm) and larger frame systems. All structural section shall have a minimum thickness of 0.146" (3.7mm) and shall be fabricated of 6063-T5 aluminum alloy.

1b)       Finish: Aluminum shall have a standard finish of AA-M12-C22-A31 (204R1, clear) or AA-M12-C22-A42 (dark bronze). Black and special finishes available upon request.

2)         Gyro-Swing Power Operator: Completely assembled and sealed unit which shall include helical gear-driven transmission, mechanical spring and bearings, all located in cast aluminum housing and filled with special lubricant for extreme temperature conditions. Attached to transmission system shall be a DC shunt wound permanent magnet motor with sealed ball bearings. Motor shall operate from 115-volt supply and require less than 5 amps at full power stall. Complete unit shall be resilient mounted with provisions for easy replacement, without removing door from pivots or frame.

3a)       Electrical Control: (Choose option) Shall be a microprocessor unit. To facilitate service and continuing operations, the unit supplied with the swinger shall also be able to operate other doors supplied for the project including slide or folding types. The microprocessor control shall allow the opening speed, closing speed, back check and latch check speed each to be adjusted separately and independently from each other to meet specific site conditions. The door shall be set to be held closed with the motor. The control system shall also be set up to provide a count of the number of operations of the doors for maintenance purposes. Adjustable opening and closing speeds shall be set in accordance with ANSI 156.10. All adjustments shall be specific and reproducible. Settings with rotary switches are not allowed.

3b)       Electrical Control: (Choose option) Self-contained unit including necessary transformer, relays, rectifiers, and other electronic components for proper operation and switching of Gyro-Swing power operator. Relays shall be plug-in type for individual replacement. All connecting harnesses shall have interlocking plugs. Controls shall also include time delay for normal cycle. Control shall include safe-swing circuit as optional switching which automatically limits power and slows door when approached from passive side.

3c)       Soft Start: Energy limiter shall be a modular electronic current control for the purpose of controlling torque to limit stress on entire entrance package.

4)         Connecting Hardware: Connect overhead (OHC)-type power operator drive arm to door with a pin linkage rotating in a self lubricated bearing, within a self adjusting slide block, traveling in an steel track and top pivot assembly. The (OHC) unit will independently support the door on heavy-duty steel top and bottom door pivots. Door shall not pivot on the shaft of operator.

5)         Emergency breakaway doorstop shall mount directly to the underside of operator housing. It shall function as a stop on all center pivoted in-swinging doors. A force of not more than 50 LBF applied at the lock stile shall cause the breakaway stop to rotate, disconnecting the power and allowing the door to swing open 180 degrees opposite its normal travel. Swinging the door into the normal mode of operation resets the breakaway door stop and power for normal automated operation.

2.03 ACTIVATING DEVICES

A.        Sensor Devices - Approach side. The Acusensor as manufactured by NABCO ENTRANCES, INC. shall be used. Sensing shall be provided in a rectangular shaped pattern with sensing immediately next to the door system. To provide optimum coverage to meet specific site conditions the sensing pattern shall be adjustable both width and depth while remaining at a full power setting.

B.        1)         Sensor Devices - Swing Side (Choose one) The Acusensor Rail system shall be provided which includes the Acusensor mounted on the header plus guide rails with a holding beam. Header mounted sensor shall be set up to provide rectangular shaped coverage with sensing immediately next to the door system. To provide optimum coverage to meet specific site conditions the sensing pattern shall be adjustable both in width and depth of coverage while remaining at full power setting.

2)            Sensor Devices - Swing Side (Choose one) The Acuswing system shall be provided which includes two sensors mounted near the top of the door to provide continuous sensing coverage on both sides of the door panel including during the opening and closing operations. Coverage shall provide a minimum of 5" beyond the leading edge of the door.

C.      Additional Specification Options for consideration - See product catalogue.

PART 3- EXECUTION

3.01 INSTALLATION

A.        Automatic door equipment shall be installed by factory-trained installers in compliance with manufacturer’s recommendations and approved shop drawings.

3.01 CLEANING AND PROTECTION

A.        After installation, clean framing members as recommended by the manufacturer. Aluminum surfaces in contact with masonry, concrete or steel shall be protected by use of neoprene gaskets, where indicated, or a coat of bituminous paint to prevent galvanic or corrosive action. Advise general contractor to protect unit from damage during subsequent construction activities.
