ANSI Approved November, 16, 2005 AMERICAN NATIONAL STANDARDS INSTITUTE, INC. 2 AMERICAN NATIONAL STANDARD An American National Standard implies a consensus of those substantially concerned 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, 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 CAUTION NOTICE: This American National Standard is permitted to be revised or withdrawn at any time.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.

To recognize this diversity, a sectional classification system has been established. Interconnected Locks 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 is, therefore, a collection of sections, each covering a specific category of items. Performance tests and, where necessary, material and dimensional requirements have been established to insure 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. 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 Association plans to 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. The BHMA numbers which indicate functions of interconnected locks do not identify grade, finish, or design and are not intended to be used without necessary supplementary information. Individual manufacturer's catalogs are consulted. Users of this Standard consult applicable local building codes as to requirements affecting the functions of locks used on fire doors and doors within a mean of egress. Some communities require use of exterior door locks having a dead bolt with a 1 in. (25.4 mm) projection for the purpose of providing greater security. Only functions compatible with the requirements of the applicable building codes are used.

SCOPE 1.1 This Standard establishes performance requirements for Interconnected Locks and includes operational tests, strength tests, security tests, cycle tests, finish tests and dimensional criteria. 1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, door and frame construction, maintenance and environmental conditions. 1.3 When interconnected locks are used in fire door assemblies, they shall have been tested and listed for use in fire doors by a Nationally Recognized Independent Testing laboratory and shall be under an in- plant follow-up inspection service. 1.4 Grade Qualifications (Also See Appendix A.) Manufacturers shall indicate the Grade level of their locks. Locks shall meet all tests for their grade listing. A Grade 1 lock shall meet all Grade 1 criteria, a Grade 2 lock shall meet all Grade 2 criteria, and a Grade 3 lock shall meet all Grade 3 criteria in each classification. 2. DEFINITIONS 2.1 Backset The distance from the edge of the door measured at the centerline of the door thickness to the cross bore at the center. 2.2 Bolts 2.2.1 Dead Bolt A lock component having an end, which protrudes from, or is withdrawn into, the lock front by action of the lock mechanism. When the door is closed and the dead bolt thrown, it extends into a hole provided in the strike, locks the door, and does not retract with end pressure. 2.2.2 Latch Bolt A lock component having a beveled end which projects from the lock front in its extended position, but is forced back into the lock case by end pressure or drawn back by action of the lock mechanism. When the door is closed, the latch bolt projects into a hole provided in the strike, and holds the door in a closed position. 2.2.3 Dead Locking Latch Bolt A type latch bolt incorporating a plunger which, when depressed, automatically locks the projected latch bolt against return by end pressure. Also called dead latch. 2.2.4 Deadlocking Latchbolt Plunger A component of the latch bolt which, when actuated, automatically locks a projected latch bolt against return by end pressure. 2.3 Cylinders 2.3.1 Cylinder The subassembly of a lock containing a plug with a keyway and cylinder body with tumbler mechanism. 2.3.2 Cylinder Body The portion of a cylinder that surrounds the plug and contains the tumbler mechanism. 2.3.3 Cylinder Plug A component of the cylinder within the body which is actuated when the correct key is inserted. 2.3.4 Interchangeable Core Cylinder A cylinder that is removable from the lock with a designated key without disassembly of the lock. 2.3.5 Cylinder Guard That portion that surrounds the otherwise exposed portion of a cylinder to protect the cylinder from wrenching, cutting, pulling or prying. 2.3.6 Cylinder Housing The portion of a lock that surrounds and retains the cylinder body. It is often part of a lock case. -,-,- 6 2.4 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. A single operation retracts all bolts. 2.5 Key A properly combinated device specifically intended to operate a corresponding cylinder . 2.6 Locked Locked is when the dead locking latch bolt or dead bolt or both cannot be retracted by operating the outside lever or knob. 2.7 Lock Front A plate fastened to the edge of a door through which the bolt(s) pass. 2.8 Loiding Insertion of a piece of celluloid or other shim material between the door and the jamb at the latch bolt location to attempt forcible retraction of the latch bolt. 2.9 Recessed Cylinder A cylinder wherein the cylinder housing face is flush with, or recessed below, the outside surface of the trim to protect the cylinder from wrenching, cutting, pulling or prying. 2.10 Strike A mortised or surface mounted plate fastened to the door frame into which the bolts project. 2.11 Strike Box A housing used in back of a strike to enclose the bolt or bolt openings. 2.12 Tailpiece A bar projecting from the back of a rim, bored lock cylinder or a push button mechanism engaging the lock mechanism and when rotated by the key or turn either locks or unlocks the lock. 2.13 Turn The component that projects or retracts a dead bolt or latch bolt by turning. Sometimes called a turnpiece or thumbturn. 2.14 Thumbpiece A lever, projecting from a handle, pressed by the thumb to retract a latch bolt. 3. GENERAL 3.1 Cylinders Cylinders supplied or mated with interconnected locks shall meet the performance requirements for the appropriate cylinder types and grade level found in the ANSI/BHMA Standard A156.5-2001 for Auxiliary Locks and Associated Products for the lock to retain their grade listing. Assemblies take the grade level of the lowest graded component. Other mechanisms are permitted to be used in lieu of cylinders providing the performance and security criteria are equivalent to that of cylinders. 3.2 Tolerances All values which do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Linear dimensions shall be ± 1/16 in (1.6 mm). Pounds or pound force shall be ± 2%. Degrees shall be ± 2 degrees. Where only minus tolerances are given, the dimensions are permitted to be exceeded at the option of the manufacturers. 3.3 Door Preparation Interconnected locks and latches shall fit the door and frame preparation as specified by the individual lock manufacturer. Roses, escutcheons, knobs, levers, turns, cylinder guards shall cover all door preparation openings. (See appendix note A7 for more information.) 3.4 Operating Trim Where levers are referenced, knobs, or handlesets are permitted to be used except for tests which apply to specific trim. 7 3.5 Reference to Other Standards The following Standards are referenced within: ASTM F476 R1996, Security Tests for Swinging Door Assemblies; ANSI/BHMA Standard A156.5-2001 for Auxiliary Locks and Associated Products, ANSI/BHMA Standard A156.2-2003 for Bored Locks, ANSI/BHMA Standard A156.13-2001 for Mortise Locks, ANSI/BHMA Standard A156.18-2000 for Materials and Finishes.
