36、on 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 area 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/ex
37、it 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 requirements as they apply to the construction, performance and operation of such systems, equipment and/or computer equipment as wel
38、l as recommended characteristics to meet four levels of security performance with Level I (lowest level security equipment) to Level IV (highest level security equipment). 1.4 Where an access control equipment and/or system incorporates the features and functions of a burglar alarm control unit, the
39、 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 conjunction with the main control unit, is necessary to support the operation (granting (authorized) or denying (unauthorize
40、d) 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 single opens, earth ground faults or wire-to-wire shorts on the circuit connection from the computer to the access control sys

45、vered by this standard shall comply with the requirements for that component. See Appendix A for a list of Standards covering components generally used in the products covered by this standard. 2.2.2 A component is not required to comply with a specic requirement that: a) Involves a feature or chara
46、cteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.2.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.2.4 Specic components are incompl
47、ete in construction features or restricted in performance capabilities. 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. 2.3 Units of measurement 2.3.1 Values stated wi
48、thout parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.3.2 Unless otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 2.4 Undated references 2.4.1 Any undated reference to a code or standard ap
49、pearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 2.5 Terminology 2.5.1 The term product as used in this standard refers to all types of access control equipment or systems of equipment.
