To recognize this diversity, a sectional classification system has been established. Closer Holder
9、Release Devices is one such 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 cate
10、gory of items. 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. The BHMA numbers which indicate type of hard
11、ware do not identify size, finish or design and are not intended to be used without necessary supplementary information. Users of this Standard who require a specific design for a product type describe it using generic terms or the manufacturers name and description desired. 3 Copyright Builders Har

15、ibed in this Standard are performed under laboratory conditions. In actual usage, results vary because of installation, maintenance and environmental conditions. 1.3 Instructions shall be included with the product requiring the end users to, (1) test the product after installation in accordance with
16、 the manufacturers criteria, (2) periodically test the products in conjunction with the fire alarm system and, (3) maintain the door closing system in working order. 2. DEFINITIONS 2.1 Adjustable Backcheck: A cushioning feature of a door closer becoming effective between 60 and 85 degrees of door op
17、ening. 2.2 Closer Holder Release Device: A floor, door or header mounted closing device connected with separate or integral releasing and fire or smoke detecting devices. 2.3 Electro-Magnetic or Electro-Mechanical Release Device: A wall, floor or door mounted appliance that releases doors from an op
18、en position for simultaneous closing upon signal from a smoke detector or other source. 3 Free Swinging Release: A function where the opening and closing control of a door closer is de-energized until a signal is received fi-om a smoke detector or other source when the closer then performs its norma
19、l function and closes the door. 2.5 Hold-Open: In this Standard, a device used in connection with a door closer holding the door in an open position against the closing force of the closer. 2.6 Multiple-Point Hold-Open: A hold-open device holding the door in more than one hold-open position without
20、manual adjustment. (Consult manufacturers catalogs for ranges of hold-open points available.) 2.7 Single-Point Hold-Open: A hold-open device holding the door open in one selective position. 3. GENERAL 3.1 These products shall allow swinging doors to close upon receiving a signal in fire or smoke eme
21、rgencies. 3.2 Upon activation by a signal to the hold-open or free swinging release device, the door shall become self- closing. 3.3 These products shall have been tested and listed for use on fire door assemblies by a Nationally Recognized Testing Laboratory (NRTL) and shall be under a follow-up in
22、-plant inspection service. 3.4 Electrical wiring of these products shall be in accordance with the National Electrical Code (ANSINFPA 70) for the appropriate class of circuit. 5 Values. Required values in this Standard are expressed in U.S. units. SI (metric) unit equivalents are 4 proximate. All va
23、lues which do not carry specific tolerances or are not marked maximum or minimum shall have the following tolerances: Linear dimension shall be h 1/16 in (1.6 mm). Pounds or pound force shall be f 2 percent. Degrees of opening shall be h 2 degrees. 5 Copyright Builders Hardware Manufacturers Associa
