2.02    DOOR CONSTRUCTION

A.  Curved Side Walls and Canopy: Shall have a standard outside diameter of 10'-0" or 12'-0" and be manufactured from six (6) extruded aluminum posts, six (6) 12" high one-piece extruded aluminum canopies and four (4) extruded aluminum bottom rails with a minimum thickness of 0.125".

B.  Door Wings: Three doors manufactured of 1 3/4" thick aluminum extrusions with minimum thickness of 0.125" and reinforced with internal aluminum door corners for strength. Door wings must utilize removable horsehair weather stripping on three sides. Door wings must be capable of folding forward or backward allowing for emergency egress.

C.  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: Overhead drive system with one 1/4 HP AC motor attached to the internal structural framing. The motor 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.      Constant regulation of rotation speed

3.      Adjustment of startup/run torque through a digital setting to minimize force required to stop door

4.      Adjustment of stopping distance through a digital setting

5.      Password-protected security over Frequency Control settings

B.  Braking Assembly: Positive braking and stopping shall be performed by electromagnetic brake assembly incorporated within the drive system. The brake unit is to remain unlocked at all times until locked by electric locking system.

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. Emergency Collapsing Mechanism: Precision-engineered door hangers and disks to allow the door wings to be collapsed, or folded and stored in a bookfold position. Hangers and disks are finished in black and provide tension to hold the door wings in position when the electric locking is released. The wings shall be capable of being collapsed outward under pressure on the outer stile not to exceed 180 pounds.

E.   Pivot: Floor mounted pivot under the center shaft to provide smooth rotation.

F.  Center Shaft: Extruded aluminum shaft with multi-point connections to the drive assembly and pivot.

G.  Electric Locking: A fail-safe electromagnetic shaft and wing lock mechanism with a (2) position post-mounted key switch to activate locking. When engaged, the electric locking will prevent rotation or collapsing of the door wings. Electric locking is disengaged by loss of power or signal from building/fire/smoke alarm (Requires a (5) wire system, 208V (3) Phase, 60Hz, 20A, service from above, by others).

H.  Surface Applied Slide Bolt Locks (Optional): Two (2) standard 1 3/4" x 5 5/8" surface-mounted deadbolt locks with removable keyed cylinders that lock into the ceiling or floor on the two interior door wings.

I.    Two-Point Recessed Locks (Optional): Two (2) standard concealed two point recessed locks with removable keyed cylinders that lock into the ceiling and floor on the two interior door wings.

J.   Anti-Entrapment Sensors (Optional): Sensors in the ceiling that detect an individual inside the revolving door compartments after the door has been locked electrically, and disengages the shaft locking mechanism for rotation of one additional segment to prevent entrapment. Required only when remote or timer control is used to engage optional electric locking.

K.  Lights: Provide (4) 5" diameter 50W Halogen lights to be recessed into ceiling (110V power service required from above by others.).

2.04    SENSOR SYSTEM

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.  T.R.S. Sensors: Active infrared sensors mounted to the top rail of each door wing that will detect presence in front of each door wing and stop the door immediately. Sensors must be adjustable for pattern size and distance from door wing.

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

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

E.  S.R.D. (Sensor Rail Doorwing): A multi-directional, closed-contact pressure sensitive switch contained within a black rubber profile mounted to the bottom rail of each door wing that will immediately stop the door's rotation if compressed.

F.   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.

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

H.  Key Switch: A two-position key switch mounted on the interior endpost that will turn the door on/off.

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.

C.   Aluminum Extrusions: Heavy-duty aluminum extrusions with minimum thickness of 0.125.

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

E.  Bumpers: rigid, rubber-tipped bumper on each door wing to prevent push bar from contacting the glass of the adjacent door

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

G.  Pivot: Floor mounted pivot under the center shaft to provide smooth rotation.

H.  Center Shaft: Extruded aluminum shaft with connections to the drive system and pivot.

2.06    FINISH

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

B.  Rotating Doors and Shaft: Anodized aluminum, kynar painted or powder-coated aluminum, stainless steel or architectural bronze (muntz metal) clad.

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