2.02MATERIALS
A. Circular Enclosure Walls and Canopy shall have a nominal diameter of 12'0" for UniTurn-12, 14’0” for UniTurn-14, 16’ for UniTurn-16, or 18’ for UniTurn-18, manufactured from slim-line straight and bent aluminum extrusion and with minimum thickness of .125 (metal-wrapped wood substrate or other metal-wrapped material substrates shall not be allowed). All internal structural support shall be I-beam construction. Segmented walls and canopy shall not be allowed.
B.Rotating Wings shall be slim-line aluminum extrusion, 2-wing configuration, finish as directed by architect.
C.Ceiling shall be white-coated laminate; center panels must be removable and serve as access hatches.
D.Ceiling Lights - provide ten (10) for UniTurn-12, twelve (12) for UniTurn-14, twelve for UniTurn-16 12volt, Quartz Halogen flush mounted ceiling light fixtures with activation control via the program selection switch or optional remote location. (203-220VAC, AC light fixtures shall not be acceptable.)
E.Glass - shall be 1/4" clear tempered in rotating section and double acting swing doors, 7/16" clear bent laminated in curved walls and curved rotating doors to assure proper weather seal throughout enclosure. Flat glass and flat segmented glass shall not be accepted in the enclosure walls. Butt Glazing shall not be acceptable. (Lexan, Marguard, Plexiglass or any other types of plastic glazing material shall not be acceptable.)
2.03OPERATION
A.Controls - must be microprocessor based "plug-in type" electronics ("hard wired" systems are not acceptable) with self-diagnostics and digital display status indicator. Digital display status indicator must be located on the interior left of the curved outside wall system. System must be capable of providing information indicating "go or no go” status, source or probable cause plus remedy.
B.Drive Assembly - must be perimeter-drive assembly with two 1/4 HP DC motors firmly attached to the internal rotating structural framing system. Motor drive wheels shall rotate on a fixed ring, and move ceiling and rotating wing assembly uniformly. Positive braking and stopping shall be performed by magnetic disc brake and wheel assemblies. (Doors with center shaft or centrally AC motor driven gear/chain/belt mechanisms will not be allowed).
C.Doors - rotating section shall include (1) pair of double acting swing doors across the center of the opening and when collapsed must provide a minimum clear exit width of 5'10" for UniTurn-12, 6'10" for UniTurn-14, 7'10" for UniTurn-16, or 8’10-1/4” for UniTurn-18. Door wings shall be electro-mechanically locked in position and released upon fire alarm input or loss of power (see Safety). Auxiliary locking devices shall not be required for proper operation of door.
D.Power Requirements - to each unit shall require (1) 208-230VAC, 60HZ lines. (Doors requiring 208-230 volts 3 phase shall not be considered equal.)
2.04SAFETY
A.Provide a minimum of five (5) primary and/or secondary safety devices located vertically on the outer edge of the rotating wing, horizontally on the wing panels, vertically at the entrances. Devices shall include touchless, single and double field, Capacitance Field Detection (CFD), zone supervised Photocell Direct Reflection (PDR) and compressible safety switches. All devices shall be incorporated as follows:
1. Vertical Safety Sensors
- Two (2) no-touch PDR sensors covering the area immediately adjacent to the enclosure wall leading edges and must include zone-supervision. Activation of the PDR within the programmed safety zone shall cause the door to stop.
- Two (2) no-touch CFD sensors placed on the leading edges of the rotating wings. Activation shall cause the door to stop.
- Two (2) compressible safety switches on the leading edges of the rotating wings. Activation shall cause the door to stop.
2. Horizontal Safety Sensors
- Two (2) no-touch CFD sensors placed on the wing panels mid-rail and must include dual-field detection. "Field 1" shall cause the door to slow when an object is detected at approximately 10" in front of the wing panel and will cause the door to resume normal speed when the object moves out of the sensor range. "Field 2" shall cause the door to stop rotation when an object is detected within 3 - 4 inches in front of the wing panel. Door will resume normal speed when the object is removed.
- Four (4) compressible safety switches shall be placed on the bottom edge of the wing panels. Activation shall cause the door to stop. Supervision of all systems must be performed by the Micro-processor Control Unit (MCU) by conducting "self-monitoring" every 3 minutes. Malfunction of any device shall cause the door to stop and the error code shall be indicated on the diagnostic display of the MCU. (Doors without the "self monitoring function" will be considered unsafe and will not be considered.)
B.Emergency Escape Doors
The center double swing door panels shall be fitted with friction bar stabilizer system and power cut-off safety switches. Door panels shall be held in place by electro-mechanical locking device and released upon fire alarm input or loss of power. The door can then be manually broken out to provide a clear and unimpeded evacuation path. Loss of power and/or fire alarm input shall be monitored by the MCU and its emergency battery unit. Activation of the emergency battery unit shall cause the door to rotate to the emergency position. (Doors that do not rotate to the emergency position during a power failure will not be considered.)
C.Emergency Stop
The door shall include an emergency stop push button on each side of the curved enclosure and close to the door opening. When the button is pressed, the rotation shall stop.
2.05HARDWARE
A.Locking System
The door will automatically cycle and rest in the full closed and lock position when the selector switch is placed in position #1. This locking system utilizes the magnetic brakes and motor drive units and is controlled by the (MCU) master control unit.
An optional electro mechanical lock is available. Device shall set a hardened 1/2 diameter dead bolt between the fixed wall structure and the rotating door sections of the revolving door. This optional lock must be completely automatic and must be controlled by the MCU through the selector switch.
B.Activation Units
Door shall be activated by manufacturer's standard flush-mounted concealed motion sensors. Activation units shall be solid state technology and work on the Doppler principle. Frequency change shall activate the revolving door. Activation units shall be concealed in the fixed ceiling area directly above throat opening. Two activation units per throat opening. (Surface mounted motion detectors are unacceptable.)
C.Program Control Device (PCD)
Provide one (1) program control device on the interior left vertical jamb of the curved wall. PCD shall provide eight (8) function capability including locked in closed position, entry/exit with start from closed position, entry/exit with start from open position, continuous rotation, exit only with start from open position, exit only with start from closed position, manual operation/forward, manual operation/reverse and summer position.
The PCD utilizes entry code access and does not require key operation during normal use of the door system.
The PCD incorporates a circular buffer memory that records the last 600 operational events of the door system and uses visual displays to notify the user when planned maintenance should be performed, if the real time clock and climate control systems are activated and if manual key lockout is in effect.
The real time clock is programmable for 3 different day schedules, 10 different operation modes per day schedule, weekly schedules and up to 16 exceptions for holidays.
The PCD can also accommodate remote diagnostics via an optional modem and client supplied telephone/data line.
2.06FINISH
A.Curved Enclosure - curved walls and canopy shall be Clear Anodized Aluminum Finish (Custom colors or finishes available).
B. Rotating Section - rotating wings and double swing doors shall be Clear Anodized Aluminum Finish (Custom colors or finishes available).
C.Ceiling - shall be white-coated laminate material.
