2.02    DOOR CONSTRUCTION

A.     Curved Side Walls and Canopy: Shall be manufactured from six (6) heavy-duty aluminum posts with minimum thickness of 0.3125", three (3) 12" high one-piece extruded aluminum canopy/track with minimum thickness of 0.3125" and an extruded aluminum bottom rail with minimum thickness of 0.125".

B.     Door Wings: Two doors shall be 2 1/4" (not 1 3/4") thick aluminum extrusions with minimum thickness of 0.125" and reinforced in the corners with solid aluminum machined bar stock for strength. Door wings must utilize removable horsehair weather stripping on all four sides. Double-acting doors are held in position with non-jamming electromagnetic locks. Upon release by door controls, or building/fire/smoke alarm, door must be capable of folding forward or backward to allow for emergency egress.

C.     Door Wings (Optional): A pair of bi-parting automatic sliding doors constructed as in Section 2.02.B.

D.     Ceiling: Shall be fabricated of formed aluminum sheet in a pie-shaped configuration. Each section must be secured in position and removable only by authorized personnel.

2.03   EQUIPMENT

A.     Drive System: Perimeter-mounted drive system consisting of two (2)1/2 HP asynchronous AC motors attached to 6" wheels mounted to the internal rotating ring. The motors shall be powered by a 208-230 VAC, 3-phase service. The motor shall utilize an internal angle encoder for constant monitoring of door position and a Frequency Controller to provide for the following characteristics:

1.    Adjustment of rotation speed through a digital setting.

2.    Adjustment of slow rotation speed through a digital setting.

3.    Constant monitoring and regulation of rotation speed.

4.      Independent adjustment of startup and run torque through digital settings to minimize force required to stop door.

5.      Adjustment of stopping distance through a digital setting.

6.       Removable remote control programmer for security over Frequency Control settings A UPS battery backup system is available to provide 4 hours of use upon power failure. The drive system shall allow for manual rotation in case of power failure.

B.     Braking Assembly: Positive braking and stopping shall be performed by DC braking incorporated within the drive system. Other auxiliary disc brakes are not considered to be equal.

C.     Controls: Microprocessor-based electronics utilizing a 2000-step Programmable Logic Controller (PLC) with the following characteristics:

1.    RAM & ROM memory

2.    Lithium battery backup

3.    Self-diagnostics for quick detection of problem source

4.    Visual display of problem source

D.     Automatic Sliding Doors (Optional): A pair of bi-parting automatic sliding doors in lieu of the two manual swing doors. Sliding doors are to be driven by an independent belt drive DC motor attached to a structural header recessed in the revolving door ceiling. Upon turning a post-mounted key switch from revolving mode to sliding mode the revolving door will stop and the sliding doors will open upon actuation of the two MMS microwave motion detectors. Upon loss of power or signal from the building/fire/smoke alarm system the sliding doors will automatically open and remain open.

E.     Lights: Eight (8) 5" diameter SOW Halogen lights to be recessed into the rotating ceiling.

2.04   SENSOR/SWITCH/BUTTON SYSTEMS

A.     M.M.S. Microwave Motion Detectors: Two (2) microwave motion detectors mounted to the canopy on each side of the door that will start the rotation of the door upon actuation. Detection pattern must be adjustable directly or by remote control.

B.     V.R.S. Sensors: Active infrared sensors mounted vertically on the inside leading edge of the rotating display cases that will detect presence in front of the door wings and display cases and stop the rotation of the door immediately.

C.     E.B.S. Sensors: Two (2) active infrared sensors mounted vertically in front of the fixed curved side walls that will detect presence in front of the curved side walls and stop the rotation of the door immediately. The EBS sensors should be capable of switching on as each door wing approaches the endpost of the side wall and off as each door wing departs the endpost of each side wall. The turning on and off of the EBS is controlled by the angle encoder within the drive system.

D.     Rotating E.B.S. Sensors: Two (2) active infrared sensors mounted vertically in front of the curved rotating side walls that will detect presence and stop the rotation of the door immediately.

E.     S.R.B. (Sensor Rail Bentwall): Two (2) multi-directional, closed-contact pressure sensitive switches contained within a black rubber profile mounted to the edge of each inbound endpost that will immediately stop the door's rotation immediately if compressed.

F.      Rotating S.R.B.: Two (2) multi-directional, closed-contact pressure sensitive switches contained within a black rubber profile mounted to the lead edge of each rotating wall that will immediately stop the door's rotation if compressed.

G.     Handicap Button: Two (2) Handicap "Push to Slow" Buttons mounted on the inbound endposts that will reduce the rotating speed of the revolving door to approximately 1/2 the regular speed for approximately one revolution.

H.   Emergency Stop Button: Two (2) Emergency Stop Buttons mounted on the inbound endposts that will immediately stop the door when pressed.

I.       Key-Switch: Provide a post-mounted key switch that will allow for the following options:

1.    On/Off

2.    Lock the door in winter position

3.    Start the door from summer/winter position

4.    Turn the revolving door off and the sliding doors on (Requires the optional sliding door package)

2.05   HARDWARE/MATERIALS

   A.     Tempered Glass: All flat glass in door wings shall be 1/4" clear tempered safety glass, all curved glass

shall be 1/4" clear bent tempered safety glass.

B.     Laminated Glass (Optional): 7/16" clear curved laminated safety glass is available as an option in the fixed side walls.

C.     Weather Stripping: Genuine horsehair weather stripping on all required edges of door wings.

D.     Rubber Seal: Rubber profiles to seal glazing, ceiling ring, and/or any other joints or gaps requiring weather-resistant seal.

2.06    FINISH

A.     Enclosure Walls: Anodized aluminum, kynar painted or powder-coated aluminum, stainless steel or architectural bronze (muntz metal) clad.
