1、ANSI/BHMA A156.37-2014 AMERICAN NATIONAL STANDARD FOR MULTIPOINT LOCKS SPONSOR BUILDERS HARDWARE MANUFACTURERS ASSOCIATION, INC. AMERICAN NATIONAL STANDARDS INSTITUTE Approved June 9, 2014 2 AMERICAN NATIONAL STANDARD An American National Standard implies a consensus of those substantially concerned
2、 with its scope and provisions. An American National Standard is intended as a guide to aid the manufacturer, the consumer and the general public. The existence of an American National Standard does not in any respect preclude anyone, whether he has approved the standard or not, from manufacturing,
3、marketing, purchasing, or using products, processes, or procedures not conforming to the standard. American National Standards are subject to periodic review and users are cautioned to obtain the latest editions. CAUTION NOTICE: This American National Standard is permitted to be revised or withdrawn
4、 at any time. The procedures of the American National Standards Institute require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of publication. Purchasers of American National Standards receive current information on all standards by calli
5、ng or writing the American National Standards Institute.

6、A Printed in the USA This Standard was approved by ANSI under the Canvass Method. BHMA was accredited on 21 March 1983 by ANSI as a sponsor using the Canvass Method. 3 FOREWORD (This Foreword is not a part of ANSI/BHMA A156.37) The general classification of builders hardware includes a wide variety
7、of items which are divided into several categories. 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 is, therefore, a collection of sections, each covering a specif
8、ic category of items. Performance tests and, where necessary, material and dimensional requirements have been established to ensure safety and stability to which the public is entitled. There are no restrictions on design except for those dimensional requirements imposed for reasons given above. Thi
9、s 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 Association plans t
10、o update, correct and revise these Standards on a regular basis. In most cases, products have been described in grade levels related to performance. Choice of grade and specific product are to be made on the basis of utility, aesthetics, security objectives and end use desired. Users of this Standar
11、d consult applicable local building codes as to requirements affecting the functions of locks used on fire doors and doors within a mean of egress. 4 TABLE OF CONTENTS TABLE OF CONTENTS 1.

In actual usage, results vary because of installation, door and frame construction, maintenance and environmental conditions. 1.3
14、Grade Qualifications (Also See Appendix A.) Manufacturers shall indicate the Grade level of their locks. Locks passing all tests within Sections 7, 8, 9 and 11 shall be assigned the respective Operational Grade; locks passing all the tests within Section 10 shall be assigned the respective Security
15、Grade. It is permissible to qualify a model to an Operational Grade only; models meeting both Operational and Security Grades shall indicate the Grade Level for each. 2. DEFINITIONS 2.1 Armored Strike A strike reinforced in such a way as to strengthen the frame to which it is applied. 2.2 Auxiliary

The cylinder body is sometimes called a cylinder shell. 2.15 Cylinder Guard That po
26、rtion that surrounds the otherwise exposed portion of a cylinder to protect the cylinder from wrenching, cutting, pulling or prying. 2.16 Cylinder Housing The portion of a mechanical lock that surrounds and retains the cylinder body. It is often part of a lock itself. 2.17 Cylinder Plug A component
27、of the cylinder within the body, which is actuated when the correct key is used. 2.18 Electrified Input Devices The electrified locks equivalent to a cylinder for reading a credential and transmitting the “key code” to the controlling device. Examples include card readers, keypads, contact memory ke
28、y readers, radio frequency (proximity) readers, optical readers, and biometric readers. 2.19 Handleset A handle with a thumbpiece. 2.20 Indicator Button The component of a hotel guest room lock which indicates on the outside that the dead bolt has been projected. 2.21 Input Devices Electrified input
29、 devices and push button mechanism. 2.22 Interconnected Lock A mechanically interconnected locking mechanism having a separate latch bolt or dead locking latch bolt and dead bolt designed for installation in round bored openings in the edge and face of a door.

33、 actuated enables entry from the outside. 2.27 Keypads Membrane or switch input readers decode digital pin codes mechanically entered. 7 2.28 Keyway The slot or hole in a cylinder plug within which a key is fully inserted to operate the cylinder. 2.29 Locked Locked is when the dead locking latch bol
34、t or dead bolt or both cannot be retracted by operating the outside lever or knob. 2.30 Lock Front A plate fastened to the edge of a door through which the bolts pass. 2.31 Loiding Insertion of a piece of celluloid or other shim material between the door and the jamb at the latch bolt location to at
35、tempt forcible retraction of the latch bolt. 2.32 Mechanical Pushbutton Mechanism Decodes the input and releases a control shaft to activate the lock drive mechanism. 2.33 Mortise Cylinder A threaded cylinder, regularly supplied with a cam to actuate the lock mechanism. 2.34 Mortise Lock or Latch A

37、der which first should be moved by the key into a predetermined position before the key or plug can release. Examples include components known as pins, side bars, discs, and the like. 2.36 Multipoint Lock A mechanical locking system which engages the door frame with bolts, latches or other fastening
38、 devices at two or more locations, and which is not an exit device (per A156.3), interconnected lock (per A156.12), or mortise lock (per A156.13). Multipoint Lock Primary Bolts Bolts which engage as a result of closing the door. Multipoint Lock Secondary Bolts Bolts which engage as a result of secon
39、dary action after the door is closed. 2.37 Narrow Stile An extruded, aluminum door where wood screws are specified a hardwood equivalent is acceptable. It may be modified to allow strike attachment simulating the manufacturers mounting instructions provided the cutaway feature is maintained subjecti
