2、NAL 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
3、 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 ed
4、itions. CAUTION NOTICE: This American National Standard is permitted to be revised or withdrawn at any time.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.

7、 hardware includes a wide variety of items which are divided into several categories. To recognize this diversity, a sectional classification system has been established. The Electrified Locking Devices Standard is a result of the collective efforts of members of several sections of the Builders Har
8、dware 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. Performance tests and, where necessary, material and dimensional requirements have been established to insure
9、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
10、 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 this Standard on a regular basis. In most cases, products have been described in grade levels related t
11、o performance. Choice of grade and specific product are to be made on the basis of utility, aesthetics, security objectives and end use described. -,-,- 4 TABLE OF CONTENTS 1. SCOPE . 5 2.

SCOPE 1.1 Electrified locking systems are usually comprised of four functional components: locking devices, input devices, controlling devices, and power supplies. This standard establishes requirement
13、s for the locking devices, whose mechanical aspects are described in the applicable BHMA product standards; in addition, where the input or controlling device or both are an integral part of the locking device, they shall also be tested with the locking device covered by this standard. This standard
14、 includes requirements for cyclical, security, operational, strength, and environmental tests for these products. 1.2 Tests described in this Standard are performed under laboratory conditions. In actual usage, results may vary because of installation, maintenance, and environmental conditions. 2. D
15、EFINITIONS 2.1 Accessory Equipment Pieces of equipment attached to or added to a product and are of such size that they are capable of being marked for identification by a catalog number or equivalent. Accessory equipment usually is dependent upon a basic part of a system for mechanical support, ele
16、ctrical input, or both; and may or may not, by itself, perform a complete function. 2.2 Controlling Device A device that processes the input signal and gives instructions to the locking device to perform certain functions. 2.3 Duty Cycle A figure of merit applied to devices designed to operate only
17、intermittently. It requires two numbers to specify: the maximum percentage of time the device may be activated and the maximum continuous activation time. 2.4 Electrical Fast Transient (EFT) “Transient“ is a term applied to either parameter (Current or voltage). It describes either parameter (curren
18、t or voltage) as a function of time during the period of adjustment (the transient period) when in a steady-state-circuit a switch is activated which changes the circuit and the parameters are adjusting to their new steady-state values. “Fast“ is an arbitrary term, which describes the time between s
19、witch activation and the parameter becoming asymptotic to its new value. For the purposes of this Standard, a transient period of a millisecond or less is regarded as a “fast transient“ or EFT. 2.5 Electrified Locking Device An electrically powered device which enables a door to be locked or unlocke
20、d in response to an electric signal. 2.6 Environmental Types 2.6.1 Full Outdoor Type An electrified device which, when installed as intended by the manufacturer, has the entire electrified locking device fully exposed to an outdoor environment. 2.6.2 Full Indoor Type An electrified locking device wh
21、ich, when installed as intended by the manufacturer, has the entire electrified locking device fully exposed to an indoor environment. 2.6.3 Locked Outdoor Type An electrified locking device which, when installed as intended by the manufacturer, has its locked side exposed to the outdoor environment
22、 and an indoor environment on the other side. 2.6.4 Locked Indoor Type An electrified locking device which, when installed as intended by the manufacturer, has its unlocked side exposed to the outdoor environment and an indoor environment on the other side. 2.7 Externally Powered Lock A lock that re
23、lies on a wired connection to an external power source for maintaining normal operation. -,-,- 6 2.8 ESD (Electro-Static Discharge) A transfer of electric charge between bodies of different electrostatic potential in proximity or through direct contact. 2.9 Fail Maintained A locking device to which
24、the removal of power does not change the locked or unlocked mode. 2.10 Fail Safe Locking a locking device with the application of power and having the device unlock when the power is removed. 2.11 Fail Secure Unlocking a locking device with the application of power and having the device lock when th
25、e power is removed. 2.12 Frame Mounted Actuator A frame mounted mechanism, which manipulates the lock or unlock function of a cooperating locking mechanism in a door in response to signals from an input or controlling device. 2.13 High Voltage Wired Lock Any locking device that operates using voltag
26、es equal to, or exceeding 30VAC RMS or 42.4VDC or AC peak and connects to external wiring for power or control. 2.14 Indoor Environment The aggregate of climate controlled conditions found within a building. 2.15 Integral Part of the Locking Device A component essential for operation that is joined
27、with the other components of the locking device assembly 2.16 Input Device The device that activates or communicates with a controlling device or the output device. 2.17 Low Voltage Wired Lock Any locking device that operates using voltages of less than 30VAC RMS or 42.4VDC or AC peak, and connects
28、to external wiring for power or control. 2.18 Low Voltage Stand Alone Lock Any locking device that operates using voltages of less than 30VAC RMS or 42.4VDC or AC peak, that does not rely on external wiring for power or control to perform its intended operation. 2.19 Outdoor Environment The aggregat
29、e of climate conditions found in the surrounding unsheltered open air. 2.20 Power Supply A source of electrical energy. 2.21 RF (Radio Frequency) Energy Electromagnetic energy at any frequency in the radio spectrum between 9 kHz and 300 gHz. 2.22 Self-Powered Lock A locking device that uses an inter
30、nal means to generate or harvest power to operate the lock without relying on a wired external connection for normal operation. 3.
