Preface
This standard is a revision of GB12663--1990 "General Technical Conditions for Anti-theft Alarm Controllers". This standard refers to the British LPS120o "Controland indicating equipment for intruder and hold-up alarms (Controland indicating equipment for intruder and hold-up alarms) January 1994 first edition". Compared with the previous version, this standard has the following important technical content changes: 1. This standard has greatly expanded the product functions, introduced the most advanced international requirements, expanded the coverage of the standard, and divided the products into three levels.
2. This standard quotes the latest version of the national electromagnetic compatibility standard that is equivalent to international standards, and selects appropriate severity levels to be in line with international standards;
3. This standard sets out product safety requirements Expanded; 4. The requirements for product marking are higher and more specific, which is conducive to product standardization. This standard will replace GB12663-1990 from the date of implementation. Appendix A and Appendix B of this standard are appendices to the standard. This standard is proposed by the Ministry of Public Security of the People's Republic of China. This standard is under the jurisdiction of the National Security Alarm System Standardization Technical Committee. This standard is drafted by the Safety and Police Electronic Product Quality Inspection Center of the Ministry of Public Security. The main drafters of this standard: Liu Yeqing and Li Xiulin.
