American National Standards are subject to periodic review and users are cautioned to obtain the latest editions. CAUTION NOTICE: This American National Standard

7、 -,-,- FOREWORD (This Foreword is not a part of ANSIBHMA Al 56.3) The general classification of builders hardware includes a wide variety of items which are divided into several categories. To recognize this diversity, a sectional classification system has been established. Exit devices is one such
8、section and this Standard is the result of the collective efforts of members of the Builders Hardware Manufacturers Association, Inc. who manufacture these products. The total Product Standards effort is therefore, a collection of sections, each covering a specific category of items. The BHMA recogn
9、ized 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 per
10、formance with Grade 1 being the highest rating. Some products described are suitable for use according to conditions and are not graded. Grade classifications indicate levels only within their own product category. Choice of grade and specific product should be made on the basis of utility, aestheti
11、cs, security objectives and end use desired. The BHMA numbers which indicate types and functions of hardware do not identi size, finish, material or design and are not intended to be used without necessary supplementary information. Users of this Standard are cautioned over the selection of exit dev
12、ices to be installed on fire doors. Only devices investigated for both fire and panic protection may be used. Labels employed by laboratories listing such devices bear the designation, “Fire Exit Hardware.“ Other devices, although suitable for many doors within a means of egress, may not be used wit
13、h fire door assemblies. The fire door must also bear a label containing the phrase, “Fire Door to be equipped with Fire Exit Hardware 3 -,-,- TABLE OF CONTENTS SCOPE . 5 1 . 2 . GENERAL 5 3 .

In actual usage, results vary because of installation, maintenance and environmental conditions. This standard establishes requirements for exit devices and trim, automatic and self-latchin
16、g flush bolts, 2. GENERAL 2.1 All exit devices shall be listed or labeled by a Nationally Recognized Testing Laboratory (NRTL) and be subject to periodic examination service. 2.2 Exit devices are available in Grades 1,2, and 3 with grade 1 being the highest grade. All are suitable for all classes of
17、 buildings and are based on the performance tests listed. A Grade 1 exit device shall be furnished with all Grade 1 trim and cylinders, when supplied, in order to retain an overall Grade 1 rating. A Grade 2 exit device shall be finished with grade 2, or higher, trim and cylinder in order to retain a
18、n overall Grade 2 rating; and similarly for Grade 3 rating. 2.3 Door coordinators Type 2 1 A are available in Grade 1 and 2. Door coordinators Type 2 1 B are available in Grade 2. Both Grades are suitable for all classes of buildings and are based on performance tests listed. 2.4 Carry-open bars are
19、 available in Grades 1 and 2. Both are suitable for all classes of buildings and are based on the performance test listed. When coordinators are installed with carry-open bars, the Grade of the combination is the lower Grade of either component. 2.5 The cycling requirements listed shall not be consi
20、dered as being in addition to those required by UL305 but comprise the total required. 2.6 All exit devices shall meet the requirements and performance tests found in Underwriters Laboratories, Inc.

27、sembly and is labeled by a NRTL and is subject to follow-up inspection service. provided in the edge of a door. Mortise exit devices can be either Panic or Fire Exit Hardware. Rim exit devices can be either Panic or Fire Exit Hardware. 2.8.4.3 2.8.4.4 Rim Exit Device An exit device with the latching
28、 mechanism applied to the face of a door.

40、 AUXILIARY ITEMS 5.1 Door Coordinator and Carry-open Bar 5.1.1 A door coordinator is used for pairs of doors opening in the same direction and having an overlapping astragal(s), rabetted meeting edges, or other devices where a prescribed sequence of closing is required. The coordinator holds open th
41、e active leaf of a pair of doors until the inactive leaf has preceded it ii the closing cycle. the inactive leaf of a pair of doors thereby preventing the inactive leaf to be opened first. The carry-open bar pushes the active door beyond the coordinator hold-open position. 5.1.3 Type 21A coordinator
42、 mechanisms shall have an internal override device to protect the active leaf of a pair of doors and its hinges or pivots from damage as a result of an abrupt or forced closing. The load to override is permitted to be preset at the factory, or adjusted or set in the field to compensate for various i
43、nstallation conditions. After an override, the mechanism shall automatically reset to normal operation the next time the active leaf is opened a minimum of 60 degrees. 5.1.2 Carry-open bars shall be provided except when automatic or self-latching flush bolts are used on 5.1.4 Marring of the doors by
44、 the coordinator or the carry-open bar shall be prevented. 5.1.5 Coordinators and carry-open bars shall be cycle tested. Coordinators with override mechanisms shall be function tested before, during, and after the cycle test. A coordinator is permitted to be tested independently or in combination wi
45、th a carry-open bar. 5.1.6 Coordinators and carry-open bars used in fire door assemblies shall have been tested and listed or labeled for use in fire doors by a nationally recognized independent testing laboratory and shall be under an in-plant follow-up inspection service. 5.2 Type 22: Removable Mu

A latch retractor mechanism shall hold bolts retracted when the door is open and a release shall permit aut
48、omatic latching when the door closes. Material and operational qualities shall be equal to the standards for exit devices. 5.3.2 Type 25: Automatic Extension Flush Bolt Set Closing the inactive leaf and then the active leaf of a pair of doors shall activate a top or top and bottom bolt, thus locking
49、 the inactive leaf. These bolts shall automatically unlatch upon opening the active leaf. Face plate size shall fit ANSI Standard Al 15.4. Type 27: Self-latching Extension Flush Bolt Set Closing the inactive leaf and then the active leaf of a pair of doors shall activate a top or a top and bottom bolt, thus locking the inactive leaf. Unlatching shall be accomplished manually. Face plate size shall fit ANSI Standard Al 15.4. 5.3.4 Bolts for labeled fire doors shall conform to all requirements l
