6、 Not to be reproduced without specific authorization from BHMA Printed in the USA 3FOREWORD (This Foreword is not a part of ANSI/BHMA A156.27) The general classification of builders hardware includes a wide variety of items which are divided into several categories. To recognize this diversity, a s
7、ectional classification system has been established. Section P, Power Doors and Components is one such section and this Standard is a result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacture this product. The total Product Standards effort
8、is, therefore, a collection of sections, each covering a specific category of items. Performance tests and, where necessary, dimensional requirements have been established to ensure a degree of safety. There are no restrictions on design except for those dimensional requirements imposed for reasons
9、of safety. This Standard is not intended to obstruct but rather to encourage the development of improved products, methods and materials. The BHMA recognizes that errors will be found, items will become obsolete, and new products, methods and materials will be developed. With this in mind, the Assoc
10、iation plans to update, correct and revise these Standards on a regular basis. It shall also be the responsibility of manufacturers to request such appropriate revisions. 4TABLE of CONTENTS 1.

SCOPE 1.1 Requirements in this standard apply to power operated revolving type doors which rotate automatically when approached by pedestrians, some small vehicular use, and manual revolving type doors for pedestrians. Included are provisions to reduce the chance of user
14、 injury and entrapment. Revolving doors for industrial or trained traffic are not covered in this Standard. 1.2 Where this standard contains specifications relating to maximum and minimum dimensions of various components of revolving doors for pedestrian use and some small vehicular traffic, such di
15、mensions are included to provide user protection for what are in the industry, standard application conditions. This standard does not attempt to assess any factors that exist with respect to custom installations. 1.3 Enclosure sizes shown in the charts shown are considered by the industry to be sta
16、ndard and practical to meet the majority of the market needs and are shown as a guide and convenience to owners and architects that are selecting a revolving door and as a convenience to installers and service persons adjusting the door and owners making periodic inspection. Deviation from enclosure
17、 sizes shown does not constitute non-compliance if the door complies with all requirements in the standard. 2.

(305 mm)
22、 or less in diameter, of revolving doors to which the wings are attached. 62.10 Clearance The minimum gap around the wing to the ceiling, enclosure, and floor, not including the weather stripping, at any point in its rotation. 2.11 Control A unit containing electrical components for automatic contro
23、l of door operation and overload protection. 2.12 Control Mat A presence sensing device that detects pressure from people or objects to give an activating signal to the automatic revolving door. 2.13 Core The rotating central portion, greater than 12 in. (305 mm) in diameter, of a large diameter rev
24、olving door to which the wings are attached. 2.14 Enclosure The walls in which the wings operate. Also known as Drum. 2.15 Entry Point Sensor A presence sensor designed to detect a person in the area between the outer leading edge of the enclosure wall and the approaching outer leading edge of the w
25、ing. 2.16 Fascia The vertical surface(s) of the canopy. 2.17 Home Position The desired at-rest position for a revolving door. Home Position “X” position (4 wing) stops in the (X) position with all four wings in contact with the entrance wall posts.; Home Position “+” position (4 wing) stops in the (
26、+) position with two wings in contact with the wall center mullions and two wings in the middle of the throat opening; Home Position “Y” position (3 wing) stops in the Y position with two wings in contact with the entrance wall posts and one wing in contact with the wall center mullion. 2.18 Knowing
27、 Act Consciously activating a switch with the knowledge of what will happen such as starting, slowing or stopping a revolving door. Switching devices may include wall or jamb-mounted contact switches such as push plates; fixed non-contact switches; and controlled access devices such as keypads, card
28、 readers, and keyswitches. 2.19 Manual Operation The capability of rotating the revolving door by a person applying a force to a door wing. 2.20 Manual Speed Control . A device used to regulate manual revolving door speed by making it difficult to push the door beyond the maximum allowed RPM. 2.21 M
29、otion Sensor A sensor designed to detect the movement of a person or equivalent at the point of entry to the door that gives an activating signal to the power operated door. 2.22 Obstruction Force The maximum static force the door is allowed to apply to a person or object measured at the outside edg
30、e of the rotating wing. 2.23 Power Operated Door A (revolving) door with a power operated mechanism that is attached to it for the purpose of mechanically opening the door upon the receipt of an activating signal. (Also called Automatic Door.) 2.24 Peripheral Speed The rotating speed of a revolving
31、door measured at the outer edge of the wing. 2.25 Presence Sensor A sensor designed to detect the presence of a stationary person in the vicinity of the doorway and give a signal to the power operated door. 2.26 Push Bar A bar attached to the wing upon which pressure is applied to set a manual revol
32、ving door in motion. A push bar is not required on automatic revolving doors. 72.27 Push to Slow Device A knowing act switch used to create an activating signal to cause the reduction of speed of the revolving door. 2.28 Safety Glass Comprised of either fully tempered or laminated glass or other saf
