36、BUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements apply to the construction, performance, and operation of physical access control equipment and/or systems intended to regulate or control: a) Entry into and/or exit from a controlled area, protected area or a restricted ar
37、ea or b) Access to or the use of a device(s) by electrical, electronic or mechanical means. 1.2 The extent of control of entry/exit may include the reporting and recording of related activity. The accuracy of the logged data is not evaluated by this standard. 1.3 This standard denes the minimum requ
38、irements as they apply to the construction, performance and operation of such systems, equipment and/or computer equipment as well as tiered characteristics to meet four levels of security performance with Level I (lowest level security equipment) to Level IV (highest level security equipment). 1.4
39、Where an access control equipment and/or system incorporates the features and functions of a burglar alarm control unit, the requirements of the Standard for Proprietary Burglar Alarm Units and Systems, UL 1076, shall also apply. 1.5 These requirements apply to computer equipment that, when used in
40、conjunction with the main control unit, is necessary to support the operation (granting (authorized) or denying (unauthorized) access) of the access control system. This Standard does not apply to supplementary computer equipment that is not necessary for operation of the access control system if si
41、ngle opens, earth ground faults or wire-to-wire shorts on the circuit connection from the computer to the access control system does not inhibit intended operation. 2 General information 2.1 For equipment utilizing power over communications cables, refer to 34.7, Power over communications cable equi
42、pment. Compliance with IEEE 802.3 (at or af) specications shall not be veried as part of these requirements. 2.2 Biometric equipment parameters such as False Accept Rates, False Reject Rates, Failure to Enroll, Failure to Acquire, etc. are not specically evaluated as part of this standard. See Secti
43、on 67, Biometric Test. 2.3 Access control systems that include duress signaling features are additionally evaluated per the Standard for Hold Up Units and Alarm Systems, UL 636. 2.4 Products intended for use in air-handling spaces in Accordance with Section 300.22, (C) of the National Electrical Cod
44、e, NFPA 70, are additionally investigated to the Standard for Fire Test for Heat and Visible Smoke Release for Discrete Products and Their Accessories Installed in Air-Handling Spaces, UL 2043.

45、REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.5 Products that utilize initiating, annunciating, and remote control devices that are not interconnected by a solid medium, such as cable, optical ber, or the like, but provide signaling by means of low power radio frequency (RF) dened by the
46、 Code of Federal Regulations (CFR), Title 47, Part 15, shall comply with Sections 81 96 of the Standard for Central-Station Burglar-Alarm Units, UL 1610, as applicable. 3 Components 3.1 Except as indicated in 3.2, a component of a product covered by this standard shall comply with the requirements f
47、or that component. See Appendix A for a list of Standards covering components generally used in the products covered by this standard. 3.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in
48、 the product covered by this standard, or b) Is superseded by a requirement in this standard. 3.3 A component shall be used in accordance with its rating established for the intended conditions of use. 3.4 Specic components are incomplete in construction features or restricted in performance capabil
49、ities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 4 Units of Measurement 4.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 4.2 Unless otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 5 Undated References 5.1 Any undated refe
