本标准详细说明了用于安全系统布局的计算机辅助绘图（CAD）符号库。这一套提供了标准化的、易于识别的图标，代表设备的形式或功能，并通过为安装样式和技术或设备类型开发具有单字符属性的通用图标，减少了符号的数量。本标准基于美国材料与试验协会（ASTM）F967《安全工程师符号（手动起草符号）标准实施规程》，随后进行了更新，包括安全系统设计和实施所需的符号。 本标准旨在为物理安全系统的设计和布局提供统一性，使CAD生成的施工图更易于安全管理、设计专业和施工行业的所有人员阅读和理解。本标准适用于建筑师、建筑承包商、系统集成商、电气承包商和安全管理人员，他们使用CAD绘制施工图、施工图和安装/竣工图，以及涉及物理安全系统布局的所有其他实体。 它的目的是作为一个模型，用于对用于安全系统设计和布局或安全系统的其他地理显示的计算机产品进行细化和整合。本标准由SIA和国际专业安全顾问协会（IAPSC）共同发起。

This standard details a Computer Aided Drafting (CAD) symbol library for security system layout. This set provides standardized, easily recognizable icons representing the form or function of the device and a reduced number of symbols through the development of generic icons with single-character attributes for the mount style and technology or device type.This standard was based on the American Society for Testing and Materials (ASTM) F967 Standard Practice for Security Engineer Symbols (manually drafted symbols) and subsequently updated to include symbols required for security system design and implementation.This standard is intended to provide uniformity in the design and layout of physical security systems, making CAD-generated construction drawings more easily read and understood by all in security management, design disciplines and construction trades.This standard is intended for implementation by architects, building contractors, system integrators, electrical contractors and security managers who use CAD to produce construction drawings, shop drawings and installation/as-built drawings, as well as all other entities that are involved with physical security system layouts. It is meant to serve as a model for elaboration and incorporation into computer products used either for security systems design and layout or other geographical displays of security systems.This standard is cosponsored by SIA and the International Association of Professional Security Consultants (IAPSC).
